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 ...

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 ...

"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

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

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 ...

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 ...

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 is smart. The progression toward embryonic quantum computing services represents a shift (you know what kind) in terms of the amount of intelligence we can apply to computing, data analytics ...

Quantum error correction (QEC) and fault-tolerant computation provide the critical framework for realising reliable quantum processors in the presence of inevitable ...

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 ...
