For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...

For quantum computers to go from research curiosities to practically useful devices, researchers need to get their errors under control. New research from Microsoft and Quantinuum has now taken a ...

Astronaut John Glenn was wary about trusting a computer. It was 1962, early in the computer age, and a room-sized machine had calculated the flight path for his upcoming orbit of Earth — the first for ...

In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert space ...

Computer scientists say they’ve cracked the science behind error-correction in quantum computers thanks to new "4D codes." Developed by Microsoft, the new codes were revealed in a blog post published ...

Microsoft and Quantinuum today announced a major breakthrough in quantum error correction. Using Quantinuum’s ion-trap hardware and Microsoft’s new qubit ...

There’s widespread agreement that most useful quantum computing will have to wait for the development of error-corrected qubits. Error correction involves ...

Google has shown that its Sycamore quantum computer can detect and fix computational errors, an essential step for large-scale quantum computing, but its current system generates more errors than it ...

Useful quantum computers are one step closer, thanks to the latest demonstration of a technique designed to stop them making mistakes. Quantum computers store information as quantum bits, or qubits.

Theoretical physicists at RIKEN have achieved a significant improvement in the efficiency of a method for fixing errors in quantum computers. This advancement could be crucial for developing larger, ...

Reliable quantum information processing in the face of errors is a major fundamental and technological challenge. Quantum error correction protects quantum states by ...
