The quantum low-density parity check (QLDPC) codes, the “holy grail” of quantum error correction research and development for 30 years, have a breakthrough ...

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 ...

In 2022, USTC researchers led by quantum physicist Pan Jianwei demonstrated the proof of principle by achieving a minimal-error-correcting unit: a distance-3 surface code logical qubit. The next year, ...

New QLDPC code family unlocks highly efficient quantum operations with lower physical qubit requirements VANCOUVER, British Columbia--(BUSINESS WIRE)--In an industry first, Photonic Inc. has ...

Quantum computers, systems that process information leveraging quantum mechanical effects, could soon outperform classical computers on some complex computational problems. These computers rely on ...

RIKEN scientists tap into AI to find a smarter method for fixing quantum errors, cutting resource demands for stable quantum machines. Theoretical physicists at RIKEN have made a key advance in ...

Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be ...

Nov. 10, 2024 — The University of Sydney has announced that quantum researchers Dominic Williamson and Nouédyn Baspin have developed what the university called “a transformative new architecture for ...

The company said it is able to reduce error rates in its quantum computing capabilities by 1,000-fold thanks to four-dimensional geometric codes. Quantum Computing ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...
