Chinese team is first outside the US to cross key threshold that determines whether practical quantum computers can work ...

In 2022, USTC researchers led by quantum physicist Pan Jianwei demonstrated the proof of principle by achieving a ...

Quantum error‐correcting codes (QECCs) have emerged as a crucial instrument in the quest to realise reliable quantum information processing. These codes utilise sophisticated mathematical frameworks ...

Just like any machine, quantum computers are prone to make errors. These errors can cause the qubits to lose their quantum states, leading to inaccurate computations. To address this problem, quantum ...

Brookhaven Lab scientists with expertise in computational modeling and nuclear physics theory developed simulations to track quantum entanglement among secondary jets of particles emitted from ...

Two-dimensional projection of a quantum spherical code composed of two copies (black and red) of the four complex dimensional Witting polytope. This code can correct up to five photon losses of any ...

To overcome this problem, high-rate quantum codes, such as quantum low-density parity-check codes, have been considered. With this approach, the logical gates, which make calculations possible, have ...

How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called ...

Computer scientist Peter Gutmann tells The Reg why it's 'bollocks' The US National Institute for Standards and Technology (NIST) has been pushing for the development of post-quantum cryptographic ...
