The central technical result is a quantum error-correcting code built on the Face-Centered Cubic (FCC) lattice — the densest possible packing of spheres in three dimensions, the arrangement at the ...

On Tuesday, Microsoft made a series of announcements related to its Azure Quantum Cloud service. Among them was a demonstration of logical operations using the largest number of error-corrected qubits ...

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

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 ...

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 in ...

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 ...

These novel error-correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields ...
