Towards quantum states of sound

Researchers make key steps towards generating quantum states of sound inside a microscopic device using laser light and single-photon measurements.

Researchers propose a simpler design for quantum computers

Today's quantum computers are complicated to build, difficult to scale up, and require temperatures colder than interstellar space to operate. These challenges have led researchers to explore the possibility of building quantum ...

A nanoantenna for long-distance, ultra-secure communication

Information storage and transfer in the manner of simple ones and zeros—as in today's classical computer technologies—is insufficient for quantum technologies under development. Now, researchers from Japan have fabricated ...

A superconducting silicon-photonic chip for quantum communication

Integrated quantum photonics (IQP) is a promising platform for realizing scalable and practical quantum information processing. Up to now, most of the demonstrations with IQP focus on improving the stability, quality, and ...

Generating entangled photons with nonlinear metasurfaces

Quantum nanophotonics is an active research field with emerging applications that range from quantum computing to imaging and telecommunications. This has motivated scientists and engineers to develop sources for entangled ...

New quantum 'stopwatch' can improve imaging technologies

Researchers at the University of Colorado Boulder have designed one of the most precise stopwatches yet—not for timing Olympic sprinters and swimmers, but for counting single photons, or the tiny packets of energy that ...

Non-line-of-sight imaging with picosecond temporal resolution

Usually, the traditional optical imaging strategies can only image the target objects within the field of camera. However, through the non-line-of-sight (NLOS) which can record the time-of-flight information about single-photon, ...
