A new quantum computing benchmark has revealed the strengths and weaknesses of several quantum processing units (QPUs). The benchmarking tests, led by a team at the Jülich Research Centre in Germany, ...

Having good neighbors can be very valuable—even in the atomic world. A team of Amsterdam physicists was able to determine an ...

A recent study conducted by the Jülich research center in Germany compared 19 quantum processors from five manufacturers. The tests measured the stability and reliability of these systems for ...

A new benchmark performed on chips from five different vendors has indicated how we can measure QPU performance as quantum computers become more advanced and useful. A new quantum computing benchmark ...

Light is fast, but travels in long wavelengths and interacts weakly with itself. The particles that make up matter are tiny and interact strongly with each other, but move slowly. Together, the two ...

Scientists at UBC have devised a chip-based device that acts as a "universal translator" for quantum computers, converting delicate microwave signals to optical ones and back with minimal loss and ...

Japanese research institute Riken has collaborated with NTT and Fixstars Amplify to launch what they claim to be the world’s first general-purpose optical quantum computer. Developed by a joint ...

Quantum scientists in Innsbruck have taken a major leap toward building the internet of the future. Using a string of calcium ions and finely tuned lasers, they created quantum nodes capable of ...

Coherence is the degree to which waves are in phase with each other and thus have the potential to interfere predictably. It underpins coherent quantum communications, in which interference between ...
