Using surface code for error-correction introduces enormous overhead requirements for systems at scale – millions of physical qubits are needed to collectively act as the thousands of logical qubits ...

“We’re excited to share these milestone results which have moved the goalposts for useful quantum computing 20 times closer.” Photonic said the codes have been stress tested to demonstrate that the ...

That’s why the field is racing to develop and implement quantum error-correction (QEC) schemes to alleviate the technology’s inherent unreliability. These approaches involve building ...

1. The infrastructure battle Quantum computing requires an entirely new infrastructure – something only a handful of companies, such as IBM, Google, and Rigetti, are actively developing.

A quantum computer, compared with traditional, familiar computers, pack magnitudes more computing power to be able to solve complex problems. To compute, traditional computers store information in ...

Quantum Circuits, Inc., announced highly efficient, scalable hardware that rounds out its full-stack quantum computing system, accelerating the path to fault tolerance and commercial readiness ...

PsiQuantum Announces Breakthrough in Architectures for Error-Corrected Quantum Computing Estimated 50X improvement in run-time efficiency would deliver impact across a broad range of applications ...

Error-corrected qubits spread individual bits of quantum information across several hardware qubits and connect these with additional qubits that allow identification and correction of errors.
