Bright background light can do more than clutter a quantum experiment. It can wash out the very features that make quantum ...

Artist's impression of a platform for linear mechanical quantum computing (LMQC). The central transparent element is a phonon beam splitter. Blue and red marbles represent individual phonons, which ...

Physicists have developed a spectral-filtering technique that strips away unwanted extra photons from quantum light sources, ...

Researchers at Harvard have created a groundbreaking metasurface that can replace bulky and complex optical components used in quantum computing with a single, ultra-thin, nanostructured layer. This ...

Optical quantum computers are gaining attention as a next-generation computing technology with high speed and scalability. However, accurately characterizing complex optical processes, where multiple ...

For all the hype surrounding quantum computers, the technology can sometimes appear to be a solution in search of a problem. Scientifically impressive, but not yet obviously useful in the real world.
