Quantum Physics
New quantum computers can operate at higher temperatures
Silicon chips operate at higher temperatures than many others, raising hopes for building quantum integrated circuits.

Quantum Physics
Quantum mechanics means some black hole orbits are impossible to predict
Computer simulations reveal that foreseeing the paths of three orbiting objects sometimes requires precision better than the quantum limit.

Quantum Physics
Scientists entangled quantum memories linked over long distances
The entanglement of quantum ‘hard drives’ is a crucial step toward creating a quantum internet.

Physics
Scientists cooled a nanoparticle to the quantum limit
Physicists decreased a nanoparticle’s motion to the lowest level allowed by quantum mechanics.

Physics
A quantum strategy could verify the solutions to unsolvable problems — in theory
A quantum technique for verifying solutions to difficult problems could apply to an “unbelievably huge” class of puzzles.

Quantum Physics
Google claimed quantum supremacy in 2019 — and sparked controversy
Google’s quantum computer outperformed the most powerful supercomputer on a task, the company reported. But some scientists aren’t fully convinced.

Quantum Physics
Quantum jitter lets heat travel across a vacuum
In a first, scientists observed tiny, vibrating membranes exchanging heat due to quantum fluctuations.

Quantum Physics
A new, theoretical type of time crystal could run without outside help
The idea tiptoes closer to the original concept of time crystals, first proposed in 2012.

Quantum Physics
Google officially lays claim to quantum supremacy
The quantum computer Sycamore reportedly performed a calculation that even the most powerful supercomputers available can’t reproduce.

Physics
Monika SchleierSmith leads elaborate quantum conversations
Monika SchleierSmith forces atoms to interact in ways that could offer insights into quantum computing, precision timekeeping and perhaps black holes.

Quantum Physics
Sean Carroll’s new book argues quantum physics leads to many worlds
‘Something Deeply Hidden’ offers a defense of The Many Worlds Interpretation of quantum mechanics.

Quantum Physics
Rumors hint that Google has accomplished quantum supremacy
Reports suggest a quantum computer has bested standard computers on one type of calculation, but practical applications are still a distant goal.
