University of Sussex researchers say their method allows microchips to be fitted together as jigsaw puzzle pieces to create more powerful quantum computers.

British researchers claim to have solved a major problem by creating more powerful quantum computers by successfully transferring data between quantum microchips.

There have been various advances in quantum research in recent years, raising hopes that we can use these powerful machines to solve complex problems.

However, even the most powerful quantum computers today only work with hundreds of qubits or quantum bits. While these machines are powerful, it will likely take many more qubits before these machines really shine.

One of the implementation challenges is knowing how many qubits a computer chip can hold. To solve this problem, researchers at the University of Sussex have demonstrated a method to transfer qubits between microchips with precision.

In a study published in the journal Nature, scientists used electric field coupling to allow qubits to move from one quantum computer chip to another.

The team dubbed the method UQ Connect and said it essentially allows chips to be fitted together as puzzle pieces that could then work together to create a more powerful quantum computer.

Researchers claimed they could transmit qubits with near 100 percent success rate and faster connection speeds. They also claim that these numbers are world records, orders of magnitude better than previous methods.

Professor Winfried Hensinger of the University of Sussex said the team knew a "modular approach" was key to building quantum computers that could solve more complex problems, as these machines would eventually be limited by the size of microchips.

"By showing that we can connect two quantum computer chips together – much like a jigsaw puzzle – and more importantly that it works so well, we open up the potential for scaling by connecting hundreds, if not thousands, of quantum computer microchips." ' he says to Hensinger. .

Hensinger is co-founder of Universal Quantum, which participated in the study. This organization received 67 million euros from the German Aerospace Center to build two quantum computers using this new method.

Last month, physicists from University College Dublin and Stanford University developed a new type of analog computer with quantum components to solve some of physics' toughest problems.

(Bloomberg) — More than 2,100 computers worldwide are managed by VMware Inc. They were affected over the weekend, researchers and cyber security officials said. The created server software was infected with ransomware that used a two-year gap

Most read by Bloomberg.

The infected machines may have targeted more than 66,000 Internet-connected computers, said Patrice Offret, founder and CEO of a French cybersecurity firm that scans the Internet for fingerprints of attackers' code. Wild cyber security agencies in France, Italy, Canada and other countries issued messages condemning the attack and urging organizations using vulnerable software to avoid the attack.

© Bloomberg Danbury, UK, Thursday 7 January 2021 A man types on a backlit keyboard. Hackers were able to inject malicious code into SolarWinds Corp this spring. With the customer list of the software product of the specified IT vendor. It includes 300,000 businesses.

"What's surprising is how quickly they attack machines," Offret wrote in an email.

Hackers began infecting more than 2,000 vulnerable computers within 24 hours, Offre said. It is not yet known which victims were raped during the murder.

“The timing was smart. Sysadmins and security teams don't work much on weekends, he said. The authors probably wanted to finish their dirty work on the weekend to get a high score.

They are the latest example of hackers exploiting old vulnerabilities in widely used software. In this case, they used the VMware ESXi "hypervisor" code for servers to extort money from organizations that have not implemented the necessary maintenance for a long time. In 2021, the company released software for this problem.

Security experts say that ever since a software company released a patch revealing a security flaw in one of its products, hackers have been scouring public data to determine whether an attack is imminent. It's a decades-long race between hackers trying to plug holes in corporate technology and security professionals trying to fix problems. Patch Tuesday, Microsoft Corp.'s monthly review of corporate technology flaws, often creates a rush to fix those flaws.

"The target vulnerability is two years old and should have been fixed, but it is clear that many servers are still unprotected," Stefano Zaneiro, professor of cyber security at the Politecnico di Milano, said in an interview.

According to Alexander Leslie, an analyst at Record Futures Inc., only one of the 426 crypto wallets affected by the hack showed a balance of around $11,700, a sign of the limited impact of the weekend hack.

"At this point, the scale of destruction and failure may outweigh any material gain for the attacker," Leslie tweeted.

"CESA is working with government and private sector partners to assess the impact of reported incidents and provide necessary assistance," said a spokesperson for the US Cybersecurity and Infrastructure Security Agency.

It is unclear whether the latest campaign is linked to last week's ransomware attack on ION Trading UK, security experts said. The breach was caused by the notorious ransomware group Lockbit, which the US Department of Justice says has been active since January 2020, hacking up to 1,000 victims worldwide and extorting at least $100 million from these organizations.

Lockbit, the group behind last week's attack on ION Trading UK that hacked derivatives trading, says it has accepted the ransom and opened its files. The company described the attack as "involving VMWare servers," but it was unclear whether the incident was related to a two-year security campaign. ION declined to comment on whether a ransom had been paid.

Physicists have discovered a new type of analog quantum computer that can solve complex physics problems that the most powerful digital supercomputers can't solve.

A new study published in the journal Nature Physics by scientists from Stanford University in the US and University College Dublin (UCD) in Ireland has shown that a new type of highly specialized analog computer with quantum elements in its circuits can solve advanced tasks. . . of quantum physics, which did not exist before. If upgraded, such devices could shed light on some of the most important unsolved problems in physics.

For example, scientists and engineers have long wanted to better understand superconductivity because existing superconducting materials, such as those used in MRI machines, bullet trains and energy-saving long-distance networks, currently only work at very low temperatures. , limiting widespread use. The holy grail of materials science is finding materials that have superconductivity at room temperature, which will revolutionize their use in many technologies.

Dr Andrew Mitchell is a theoretical physicist at the UCD Center for Quantum Engineering, Science and Technology (C-QuEST), UCD School of Physics, and co-author of the paper.

He said: "Some problems are too complex for even the fastest digital classical computers to solve. An important example is the detailed modeling of complex quantum materials such as high-temperature superconductors; such calculations are beyond our current capabilities. Realistic models are required to simulate properties. "Exponential Computing Time and Memory Requirements”.

“However, technological and engineering advances that have led to the digital revolution have resulted in an unprecedented ability to control matter at the nanoscale. This has allowed us to build specialized analog computers called "quantum simulators" that solve precise models in quantum physics. , exploiting the properties of quantum mechanics inherent in its nanoscale components, has developed analog devices with quantum components that can solve some of the problems of quantum physics."

The architecture of these new quantum devices consists of a metal-semiconductor hybrid embedded in a nanoelectronic circuit developed by researchers at Stanford, UCD and the Department of Energy's SLAC National Accelerator Laboratory (Stanford). Stanford's Experimental Nanotechnology, led by Professor David Goldhaber-Gordon, built and operated the device, while UCD's Dr Mitchell did the theory and modelling.

Professor Goldhaber-Gordon, a researcher at Stanford's Institute for Materials and Energy Science, said: "We always create mathematical models that we hope will capture the essence of the phenomenon we are interested in, but if we think so, it is correct.", often within a reasonable time. cannot be resolved."

With the quantum simulator, 'we have a handle that we've never had before,' says Professor Goldhaber-Gordon.

Why analog?

According to Goldhaber-Gordon, the basic idea behind these analog devices is to create some kind of hardware analog of the problem you want to solve, rather than writing computer code for a programmable digital computer. For example, suppose you want to predict the motions of planets in the night sky and the timing of eclipses. You can do this by building a mechanical model of the solar system, where one turns a knob and interlocking spinning gears represent the motions of the moon and planets.

In fact, this process was found in an ancient shipwreck near a Greek island that is over 2,000 years old. This device can be considered as one of the first analog computers.

Until it exploded, the analog machine of the 20th century. They were used until the late 20th century for mathematical calculations that were too complex for the most advanced digital computers of the time.

But to solve the problems of quantum physics, the device must have quantum components. The new quantum simulator architecture consists of electronic circuits with nanoscale components whose properties are governed by the laws of quantum mechanics. It is important to note that many of these components can be created, each of which functions essentially the same as the others.

This is crucial for analog simulations of quantum matter, where each electronic component of the circuit is a substitute for a simulated atom and "behaves like an artificial atom". Just as different atoms of the same type in a substance behave in the same way, so the different electronic components of an analog computer must behave in the same way.

The new design therefore offers a unique way to scale the technology from single devices to large networks capable of simulating quantum matter. The researchers also showed that new microscopic quantum interactions could be implemented in such devices. The work is a step toward developing a new generation of scalable solid-state analog quantum computers.

The first quanta

To demonstrate the power of analog quantum computing with their new quantum simulator platform, the researchers first analyzed a simple circuit with two quantum elements connected to each other.

The device simulates a model of two atoms connected by a special quantum interaction. By controlling the electrical energy, the researchers were able to create a new state of matter where the electrons appear to have only 1/3 of their normal electrical charge, the so-called 'Z3 parafermion'. These elusive states have been proposed as the basis for future topological quantum computing, but have never been created in electronic devices in the laboratory.

'By scaling the two-material quantum simulator to the nanoscale, we hope to be able to simulate much more complex systems that modern computers cannot handle,' said Dr. Mitchell. "This could be the first step towards finally solving the most amazing mystery of our quantum universe."

An online auction in the San Benito School District has sold thousands of computers and tablets, some containing personal information of employees and students, a computer store owner said Wednesday.

David Avila, co-owner of Brownsville-based RDA Technologies, said records from South Texas Auction show the district sold more than 2,000 computers and 1,500 tablets during an online auction on July 23.

Avila said she purchased about 700 computers in the district before finding at least 11 hard drives containing district data, including staff and student names, phone numbers and addresses, student grades and some bank account information.

He said that of the 11 computers on which he found personal information, one was destroyed.

He's now offering to sell his unchecked District 10 and 503 for $99,579.04, depending on the make and model of the computer.

"They asked me to sell them the team," he said. "They insist on making an offer. If they want to buy our shares, they can buy them. We don't sue, you ask the price."

But he said about 200 of the computers he upgraded after inspections found that district information had not been sold to districts, adding that because school districts hire your company to clean the hard drives on your computers, administrators can rely on their own inspections. to destroy it.

"We have a good reputation and that speaks for itself," Avila said. "Why do people trust us to destroy data?"

Corporate offers

During talks with the district that lasted about three months, Avila said officials offered him $138,619 to buy a computer that he bought for $29,000, a dispute between district officials.

For his part, Avila said he turned down the offer because he did not want to sign the confidentiality clause that was part of the deal.

"We sell only if there is no non-disclosure agreement," he said. "We don't want to get involved in hiding the truth."

computer buyer

Meanwhile, a Utah woman said her husband also bought the district's computers at auction, before discovering that the district had failed to erase at least one computer hard drive.

"So far we can only see one of the computers and the hard drive has not been erased," she said in a private message on Facebook.

On-site inspection

Earlier this month, the Valley Morning Star checked a computer in Avila's office, chosen by Avila, and found the teacher's bank account number; bank account numbers for some teachers; List teachers by name, username, and email; Student name, registration number, and grade. List of failing students, including names; List of immigrant students, including name, student identification number, and grade level; and the IP and MAC numbers of copiers and printers in the area.

Discuss the contract proposal

On Friday, Inspector Teresa Cervillon posted a statement on the district's website saying Avila offered to sign a contract saying she would erase the computer's hard drive while signing a non-disclosure agreement.

On Wednesday, Avila turned down an offer to sign such a deal.

Avila said that during an Oct. 31 meeting with Servellon and District Technology Director Todd English, the terms of that agreement were "mentioned."

"It was mentioned," he said. "We mention the types of services we offer, but we never offer them as a solution."

Area data request

Last month, district officials issued a statement for the first time to update the public on PC sales.

“The San Benito CISD Center publicly announced that a local electronics recycling company, RDA Technologies, has purchased area computers that may contain historical data for the area,” Cervillon said Friday. “Once the district became aware of this, it contacted RDA Technologies to reset the affected device and determine what information, if any, was on the device.”

“Over several weeks, Mr. Avila has repeatedly refused to provide the district with further details about the information allegedly contained in the device purchased, after which the district attempts to recover the laptop and CPU to perform its own analysis,” he said.

"Despite numerous attempts to reach a reasonable settlement with RDA Technologies, the District has been unable to substantiate the allegation of sensitive personal information on this device," it said.

“Unless the District is able to perform a comprehensive analysis of equipment purchased from RDA Technologies and to be able to identify specific individuals whose sensitive personal information may be affected in order to provide appropriate services to those individuals, any public display of District Personal Equipment information is required if it is an “employee or A sensitive student, he's misguided and irresponsible," Cervillon said.

The county also reported the matter, along with RDA Technologies management, to the Consumer Protection Division of the Texas Attorney General's Office.

Avila: The company offers check-ups

Meanwhile, Avila said he has given county officials the ability to search computers.

He said English checked a computer in the company's office on Oct. 28.

“At that time, RDA Technologies only allowed district personnel to briefly scan two devices, neither of which contained sensitive personal information,” Cervillon said. Furthermore, Mr. Avila's personal data contains no indication of sensitive personal information contained in the device purchased.

Avila said he gave officers the opportunity to check the computers on January 11.
