AI method determines quantum advantage for advanced computing

Creating quantum computers is costly and time-consuming, and the resulting devices are not guaranteed to exhibit any quantum advantage—that is, they often do not operate faster than a conventional computer. So researchers ...

On the way to quantum networks

Physicists at LMU, together with colleagues at Saarland University, have successfully demonstrated the transport of an entangled state between an atom and a photon via an optic fiber over a distance of up to 20 km—thus ...

How to verify that quantum chips are computing correctly

In a step toward practical quantum computing, researchers from MIT, Google, and elsewhere have designed a system that can verify when quantum chips have accurately performed complex computations that classical computers can't.

A neural network as an anchor point

Quantum mechanics is a well-established theory, but at a macroscopic level it leads to intractable contradictions. Now ETH physicists are proposing to resolve the problem with the aid of neural networks.

Quantum physics: Ménage à trois photon-style

Entanglement is one of the properties specific to quantum particles. When two photons become entangled, for instance, the quantum state of the first will correlate perfectly with the quantum state of the second, even if they ...
