Unlike binary bits of information in ordinary computers, “qubits” consist of quantum particles that have some probability of being in each of two states, designated |0 and |1 , at the same time. When ...

Following up on Microsoft’s announcement of a qubit based on completely new physics, Amazon is publishing a paper describing a very different take on quantum computing hardware. The system mixes two ...

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 ...

There’s a strong consensus that tackling most useful problems with a quantum computer will require that the computer be capable of error correction. There is ...

Surface code: illustration of how error correction works for bit and phase flips. The measure qubits on light blue backgrounds check for phase flip errors while the ...

Low-density parity-check (LDPC) codes are a type of error-correction code increasingly used in applications requiring highly efficient information transfer over channels with the presence of ...

The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness. Unlike binary bits of information in ordinary computers, “qubits” consist ...
