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 ...

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 ...

Computing Error-corrected qubits 800 times more reliable after breakthrough, paving the way for 'next level' of quantum computing News By Keumars Afifi-Sabet published 4 April 2024 ...

This creates a notable problem. Like many other qubit technologies, quantum dots need to be kept below 1 Kelvin in order to keep the environment from interfering with the qubit. And, as anyone who ...

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 ...

Christian Weedbrook, Xanadu’s founder and chief executive officer, said the development means it is possible to envision a quantum-computing system operating at the scale of a data centre, with ...

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.

Photonic Inc: Connectivity diagrams of surface (left) and SHYPS (right) codes in practice. In a full implementation of SHYPS codes and comparably scaled implementation of surface codes, SHYPS ...
