The linking of two distant qubits will help to develop larger, more complex quantum computers based on silicon quantum dots In a demonstration that promises to help scale up quantum computers based on ...

“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 ...

Researchers at the Russian state Atomic Energy Corporation Rosatom and Lomonosov Moscow State University have developed a ...

Quantum computers based on ions or atoms have one major advantage: The qubits themselves aren’t manufactured, and there’s no device-to-device variability among atoms. Every atom is the same and should ...

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 ...

Quantum computers require extreme cooling to perform reliable calculations. One of the challenges preventing quantum computers from entering society is the difficulty of freezing the qubits to ...
