Breakthrough proof clears path for quantum AI

Convolutional neural networks running on quantum computers have generated significant buzz for their potential to analyze quantum data better than classical computers can. While a fundamental solvability problem known as ...

Cooling radio waves to their quantum ground state

Researchers at Delft University of Technology have found a new way to cool radio waves all the way down to their quantum ground state. To do so, they used circuits that employ an analog of the so-called laser cooling technique ...

Implementing a 46-node quantum metropolitan area network

Quantum key distribution (QKD) is a method used for secure or secret key exchanges between two remote users. Using secure communication, cyberscientists ultimately aim to establish a global quantum network. Existing field ...

Optical chip protects quantum technology from errors

In today's digital infrastructure, the data-bits we use to send and process information can either be 0 or 1. Being able to correct possible errors that may occur in computations using these bits is a vital part of information ...

A 15-user quantum secure direct communication network

Quantum secure direct communication (QSDC) based on entanglement can directly transmit confidential information. Scientist in China explored a QSDC network based on time-energy entanglement and sum-frequency generation. The ...

Can we see quantum correlations at the macroscopic scale?

One of the most fundamental features of quantum physics is Bell nonlocality: the fact that the predictions of quantum mechanics cannot be explained by any local (classical) theory. This has remarkable conceptual consequences ...
