Physicists have succeeded in coupling two Andreev qubits coherently over a macroscopic distance for the first time. They achieved this with the help of microwave photons generated in a narrow ...

Researchers have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating millions of ...

In order to scale quantum computers, more qubits must be added and interconnected. However, prior attempts to do this have ...

“Our demonstration was on a two-qubit system and using a particular type of defect”, says Tim Taminiau who supervised the research. “A key challenge is to maintain and further improve the gate quality ...

Quantum physicists have found a way to let a single qubit experience several different “journeys” through time at once, ...

Physicists at the University of Oxford have taken a significant step toward solving one of the most daunting challenges in quantum computing: how to connect multiple quantum processors to work ...

Performing complex algorithms on quantum computers will eventually require access to tens of thousands of hardware qubits. For most of the technologies being developed, this creates a problem: It’s ...
