Quantum mechanics is an extraordinarily successful scientific theory, on which much of our technology-obsessed lifestyles depend. It is also bewildering. Although the theory works, it leaves physicists chasing probabilities instead of certainties and breaks the link between cause and effect. It gives us particles that are waves and waves that are particles, cats that seem … Read more
One-minute review A high-end wireless gaming headset designed for Xbox, the JBL Quantum 910X falls just short of earning a place among the best Xbox Series X headsets. That’s not to say that it isn’t still a formidable option, however, as it offers an excellent level of comfort that’s backed up by rich audio; it’s … Read more
Unlike traditional computing that uses binary bits, quantum computing uses quantum bits or ‘qubits’, enabling simultaneous processing of vast amounts of data, potentially solving complex problems much faster than conventional computers. In a major step forward for quantum computing, Microsoft and Quantinuum have unveiled the most reliable logical qubits to date, boasting an error rate … Read more
The dream of quantum computing has always been exciting: What if we could build a machine working at the quantum level that could tackle complex calculations exponentially faster than a computer limited by classical physics? But despite seeing IBM, Google and others announce iterative quantum computing hardware, they’re still not being used for any practical … Read more
To experimentally realize a curved spacetime such as a black hole requires a specific relative motion between the excitations and the background medium. One-dimensional supersonic flow, the archetypal example of an acoustic black hole, provides a platform for observations of Hawking radiation in both classical20,21 and quantum fluids9,10,22. More complex phenomena such as Penrose superradiance … Read more
In hindsight, it seems prophetic that the title of a Nature paper published on 1 March 1974 ended with a question mark: “Black hole explosions?” Stephen Hawking’s landmark idea about what is now known as Hawking radiation1 has just turned 50. The more physicists have tried to test his theory over the past half-century, the … Read more
Trapped atomic ions are among the most advanced technologies for realizing quantum computation and quantum simulation, based on a combination of high-fidelity quantum gates1,2,3 and long coherence times7. These have been used to realize small-scale quantum algorithms and quantum error correction protocols. However, scaling the system size to support orders-of-magnitude more qubits8,9 seems highly challenging10,11,12,13. … Read more

In a significant move for the field of quantum computing, NVIDIA has joined forces with Australia’s Pawsey Supercomputing Centre. This collaboration is poised to make a substantial impact on research by combining NVIDIA’s cutting-edge CUDA Quantum platform with the deployment of the powerful Grace Hopper Superchips. These advancements are expected to propel computational capabilities at … Read more
IBM has teamed up with Korea Quantum Computing (KQC) in a strategic partnership that’s set to advance on some computing. This alliance is not just a handshake between two companies; it’s a fusion of IBM’s trailblazing AI software and quantum computing services with KQC’s ambition to push the boundaries of technology. “We are excited to … Read more
