Quantum physics news, features and articles

A four-atom molecule has broken the record for coldest large molecule.

Physicists created a 'quantum vortex,' which flows with 500 times less viscosity than water and could be used to study the space-time warping caused by black holes.

Researchers at the LIGO gravitational wave observatory used a new technique called frequency-dependent squeezing to boost weak signals above quantum noise.

The stunning experiment, which reconstructs the properties of entangled photons from a 2D interference pattern, could be used to design faster quantum computers.

In this extract from the book 'The One Thing You Need to Know', author Marcus Chown explains how the Dirac Equation came to be.

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy.

Physicists have placed part of a sapphire crystal into a quantum superposition, making it the heaviest object to show quantum effects, in a new take on Erwin Schrödinger's famous cat experiment.

Within a month of the Big Bang, a second cosmic explosion may have given the universe its invisible dark matter, new research suggests.

In quantum physics, particles exist in many states at once until you measure them. Can reality really work that way?

In some interpretations of quantum mechanics, such as the Many-Worlds interpretation or the Pilot Wave Theory, parallel universes may form every time a subatomic particle goes through any interaction.
