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

However, GKP codes rely on squeezed states—quantum states that are difficult to generate and control. Consequently, GKP codes have been challenging to implement in practical experiments ...

Quantum computers can one day be vastly more powerful than the most powerful supercomputers on the planet — but only if scientists find ways to fix the extremely high error rate in qubits.

In its effort to achieve fault tolerant quantum computing, Microsoft on Thursday unveiled its new error-correcting code, which uses four-dimensional geometric codes to help reliably transmit ...

Why repetition codes matter The focus on repetition codes isn't arbitrary. While other quantum error-correcting codes, like surface codes, have only achieved small distances and relatively high ...

Paris – March 11, 2025 – Fault-tolerant quantum computing company Alice & Bob today announced what they said is a significant advancement in cat qubit technology to reduce errors in quantum computers.

The researchers have proven PLANAR's effectiveness on surface codes under particular noise conditions and plan to adapt it for non-planar graphs with finite genus, opening the door to broader use ...
