Quantum entanglement makes quantum communication even more secure
Bell tests proved that quantum mechanics really is “spooky.” Now they’ve made quantum communication even more hacker-proof.

Aliens could send quantum messages to Earth, calculations suggest
Scientists are developing quantum communications networks on Earth. Aliens, if they exist, could be going further.

Quantum physics exponentially improves some types of machine learning
It wasn’t entirely clear if quantum computers could improve machine learning in practice, but new experiments and theoretical proofs show that it can.

A new gravity sensor used atoms’ weird quantum behavior to peer underground
Quantum sensors promise to be more accurate and stable in the long run than other gravity probes.

‘From Data to Quanta’ defends Niels Bohr’s view of quantum mechanics
In his new book, philosopher Slobodan Perović corrects misconceptions about physicist Niels Bohr’s work.

The quantum ‘boomerang’ effect has been seen for the first time
Jostled particles return to their starting points in certain materials, an experiment reveals, confirming theoretical predictions.

Quantum particles can feel the influence of gravitational fields they never touch
A quantum phenomenon predicted in 1959, the Aharonov-Bohm effect, also applies to gravity.

A century of quantum mechanics questions the fundamental nature of reality
A century after the quantum revolution, a lot of uncertainty remains.

Quantum physics requires imaginary numbers to explain reality
Quantum theory based only on real numbers fails to explain the results of two new experiments.

Physicists have coaxed ultracold atoms into an elusive form of quantum matter
Quantum spin liquids could be used to help protect fragile information in quantum computers.

Scientists finally detected a quantum effect that blocks atoms from scattering light
When all available quantum states are full, atoms can’t scatter light, thanks to the Pauli exclusion principle, new experiments show.

Scientists are one step closer to error-correcting quantum computers
In a quantum computer made with trapped ions, multiple quantum bits were combined into one to detect mistakes.
