Live Science on MSNSmall, room-temperature quantum computers that use light on the horizon after breakthrough, scientists sayScientists 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.
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 ...
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.
The trouble is that most current error-correction techniques are either difficult to scale, resource-intensive, or both. The more physical qubits required to provide fault tolerance for a quantum ...

From spin glasses to quantum codes: Researchers develop optimal error correction algorithmScientists 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 ...
Researchers have been able to demonstrate a quantum exponential scaling advantage, using two 127-qubit IBM Quantum Eagle processor-powered quantum computers, over the cloud. The paper ...
Timing error detection and correction (EDAC) in resilient circuits helps eliminate excess timing margins. However, it faces misdetection risks when critical pat ...
