A device smaller than a grain of dust is emerging as a surprisingly powerful candidate to reshape how quantum computers are built and scaled. Instead of relying on room-filling optics and fragile lab ...

Researchers at Harvard have created a groundbreaking metasurface that can replace bulky and complex optical components used in quantum computing with a single, ultra-thin, nanostructured layer. This ...

A vital ingredient for making quantum computers truly useful just might be conventional computers. That was the message from a gathering of researchers this month, which explained that classical ...

Quantum computers can compare molecules that are much larger than the ones classical computers can compute, Accenture said on its website. “The big hope is that a quantum computer can simulate any ...

Japan has switched on the first quantum computer that has been designed and built with components from the country. The system is now ready to take on workloads from its base at the University of ...

For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive. That’s ...

Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical ...

Paris-based quantum computing startup Alice & Bob has announced a stunning breakthrough in quantum computing: its qubits can now resist bit-flip errors for more than an hour. That’s four times longer ...
