Quantum Physics
Enter the quantum realm with Live Science, where the regular rules of physics don't apply and objective reality doesn't exist. Quantum physics is a field of science in which researchers study energy and matter at their most fundamental level.
At Live Science, our expert writers and editors break down the most important and stunning quantum experiments, explain quantum cognition — the physics theory that could predict human behavior — and discover how physicists are making light move simultaneously forwards and backwards in time. So, if you're ready to explore the weird world of quantum mechanics, check out the latest news, features and articles about quantum physics.
Latest about Quantum Physics
World's largest gravitational wave observatory squeezes light beyond the 'quantum limit'
By Ben Turner published
Researchers at the LIGO gravitational wave observatory used a new technique called frequency-dependent squeezing to boost weak signals above quantum noise.
Quantum 'yin-yang' shows two photons being entangled in real-time
By Ben Turner published
The stunning experiment, which reconstructs the properties of entangled photons from a 2D interference pattern, could be used to design faster quantum computers.
'The most magical equation in physics': How Paul Dirac accidentally revealed the strange world of antimatter
By Marcus Chown published
In this extract from the book 'The One Thing You Need to Know', author Marcus Chown explains how the Dirac Equation came to be.
Distortions in space-time could put Einstein's theory of relativity to the ultimate test
By Robert Lea published
Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy.
World's heaviest Schrödinger's cat made in quantum crystal visible to the naked eye
By Ben Turner published
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.
There may have been a second Big Bang, new research suggests
By Paul Sutter published
Within a month of the Big Bang, a second cosmic explosion may have given the universe its invisible dark matter, new research suggests.
Does reality exist when we're not looking?
By Paul Sutter published
In quantum physics, particles exist in many states at once until you measure them. Can reality really work that way?
Do quantum universes really exist?
By Paul Sutter published
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.
