Quantum computers promise significantly shorter computing times for complex problems. But there are still only a few quantum computers worldwide with a limited number of so-called qubits. However, ...

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 ...

Researchers have identified a “nightmare scenario” calculation related to exotic types of quantum matter that would be impossible to solve, even for a very efficient quantum computer. Without the ...

A quantum computer made of charged atoms can catch its own errors when performing any operation – a meaningful step towards more reliable and practical quantum computers. Conventional computers ...

An international research team has placed quantum light emitters onto silicon chips with roughly 90% success by using tiny triangles made of folded DNA, a result that exceeds the efficiency ceiling ...
