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 ...

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

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 ...

What is it about quantum computers that makes them more powerful than conventional machines? A new experiment shows that the property of “quantum contextuality” may be a key ingredient. Quantum ...

Quantum computers are gaining a reputation among chemists and material scientists as promising tools that can tackle problems ...

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic communications to quantum sensors, the manipulation of photons underpins ...

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.

PALO ALTO, Calif.--(BUSINESS WIRE)--PsiQuantum today announced it has raised $1 billion in funding for its Series E round to build the world’s first commercially useful, fault-tolerant quantum ...
