Alphabet is seeing some solid results from its Willow chip. Nvidia ties traditional and quantum computing together. IonQ is the quantum computing accuracy leader. Quantum computing has taken a step ...

IonQ and D-Wave Quantum are taking different approaches to quantum computing. Their risks of failure are much higher than their chances of success. Quantum computing is an emerging industry that is ...

The unveiling by IBM of two new quantum supercomputers and Denmark's plans to develop "the world's most powerful commercial quantum computer" mark just two of the latest developments in quantum ...

Senior Research Leader and Deputy Director, Science and Emerging Technology, RAND Europe The unveiling by IBM of two new quantum supercomputers and Denmark’s plans to develop “the world’s most ...

Inside a warehouse turned laboratory in suburban Maryland, a team of theoretical physicists and engineers is racing to build a quantum processor powerful enough to surpass the most advanced computers ...

The low-noise, high-gain properties needed for high-performance quantum computing can be realized in a microwave photonic circuit device called a Josephson traveling-wave parametric amplifier (JTWPA), ...

Computer science, at its most fundamental, is all about inputs and outputs. Consider the simple case of multiplying two numbers on a pocket calculator. You punch in some inputs — the specific numbers ...

Physicists at Heidelberg University have developed a new theory that finally unites two long-standing and seemingly incompatible views of how exotic particles behave inside quantum matter. In some ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...
