A multitude of experiments have shown the mysterious phenomena of quantum mechanics to be how the universe functions. The scientists behind these experiments won the 2022 Nobel Prize in physics.
Two particles are said to be entangled when one cannot be perfectly described without information about the other being included.

So far researchers have only been able to control a handful of qubits — the basic units of information in a quantum computer. A new approach could help them control millions at a time.
Entangled photons have been used for the first time to encode information in a hologram, which could lead to improved medical diagnosis and speed up the advance of quantum technologies.

We usually think of quantum entanglement in the realm of atomic systems, but now it’s been scaled up to relatively massive objects. This opens the door to new kinds of technology.

As companies make quantum computers available through their cloud services, take a look at what it means for computing to move beyond classical mechanics and into quantum physics.
When black holes collide, gravitational waves are created in space itself (image is a computer simulation).

Einstein called entanglement “spooky action at a distance”. But now it’s been used to design an incredibly sensitive detection method for gravitational waves.
As hackers get more sophisticated in their cyber crime efforts we need to look to new technology to make our systems more secure, and potentially unhackable. So how can quantum physics help?
