There’s widespread agreement that most useful quantum computing will have to wait for the development of error-corrected qubits. Error correction involves ...

A research team has now introduced a new method, called RE² (Retrieving Examples with similar Explanation), to address a long-standing challenge: finding reference examples that truly help models ...

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 ...

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 ...

Carbon code is different, says Svore. “We do not consider the Carbon code to be an LDPC code,” she says. Technically, Carbon code is a stabilizer code of the Calderbank-Shor-Steane variety, which is a ...

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 ...
