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 ...

Classical public-key cryptography derives its security from integer factorisation. Diagram by Venus Kolhi. Quantum computers bring exponential computing power, ultrafast calculations, advanced ...

The race to build the first truly useful quantum computer just got more exciting. A quantum computer made from extremely cold atoms has now passed some of the most important milestones towards ...

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 ...
