Scientists say they’ve cracked a key challenge in scalable quantum hardware after generating an error-correcting, light-based qubit on a chip for the first time.

“While the industry is making massive investments in quantum computing infrastructure and scaling the number of qubits, our ...

Qedma specializes in error mitigation software. Its main piece of software, QESEM, analyzes noise patterns to suppress some ...

A multinational team has cracked a long-standing barrier to reliable quantum computing by inventing an algorithm that lets ordinary computers faithfully mimic a fault-tolerant quantum circuit built on ...

A research team has achieved the holy grail of quantum computing: an exponential speedup that’s unconditional. By using clever error correction and IBM’s powerful 127-qubit processors, they tackled a ...

Quantum computers have the potential to speed up computation, help design new medicines, break codes, and discover exotic new materials—but that's only when they are truly functional.

Based on the findings, the new 4D code family could represent the second breakthrough in quantum error-correction in as many weeks. On June 10, IBM made a similar statement when it announced that ...

Scientists have developed an exact approach to a key quantum error correction problem once believed to be unsolvable, and have shown that what appeared to be hardware ...

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 ...

In this paper, a novel signal injection method is proposed to correct the position error under sensorless control, with the help of two sets of windings in a du ...
