Two companies that are racing to develop a photonic quantum computer using photonic qubits are PsiQuantum, based in Palo Alto ...

Quantum physicists at the Australian National University (ANU) have achieved a major milestone by directly observing atoms ...

In a laboratory at Oxford University, scientists have achieved something that once seemed science fiction: they made two separate quantum computers work together as one. Instead of being connected by ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

A breakthrough experiment led by a team from the University of Stuttgart in Germany brings a quantum internet a step closer, with physicists teleporting a quantum state between photons produced by ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

The concept of entanglement links far-flung particles. That relationship can prove that someone is in the location they claim ...

EPFL researchers have built a device that detects individual microwave photons with up to 70 percent efficiency, operating continuously and without complex reset steps.

A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

Netherlands company’s demonstration of a production-ready method to reduce errors in a quantum computer is a first for ...
