It is widely repeated in the popular literature and elsewhere that the singularity at the center of a black hole is a point. It is not true. Two observers who free-fall into a spherical black hole along two different angular trajectories at the same time…

Use of TLS 1.3, which fixes some known deficiencies in TLS 1.2, is growing. This document specifies that no changes will be approved for TLS 1.2 outside of urgent security fixes (as determined by TLS Working Group consensus), new TLS Exporter Labels, and…

Sometimes when you build software, you shave a yak so deeply that you end up with a surprisingly nice sweater (while the yak, presumably, wonders why it is suddenly rather drafty).…

Caltech's Garnet Chan and colleagues computed the ground-state energy of nitrogenase's FeMo-co cluster to chemical accuracy using only classical methods.…

Let’s Encrypt is committed to a post-quantum-safe Web PKI. The path we’re planning to take is Merkle Tree Certificates (“MTCs”), a new approach that adds post-quantum authentication to the web without sacrificing the speed and reliability that have made…

Quantum computing remains in a superposition of "viable" and "not viable," but this game is intriguing either way.

Microsoft’s Majorana 2 chip uses a new material stack that promises quantum computing much sooner.

Honeywell International Inc.-backed quantum computing company Quantinuum Inc. is considering increasing the size of its initial public offering, according to a person familiar with the matter.

IBM will invest more than $10 billion over five years to build a fault-tolerant quantum computer by 2029. The ambitious plan combines heavy R&D spending, new manufacturing ventures and government support. Success could reshape multiple industries.

Particles of light cannot be divided into smaller particles, but if you try to snip off the end of one, instead of shortening it multiplies

The most advanced lithography system, crucial for future advanced memory and computer chips, will play a key role in scaling up quantum technology.

A new room-temperature quantum device uses twisted light to entangle photons and electrons, overcoming one of the biggest hurdles in quantum technology.…

Apple says testing missed flaws in new encryption designed to protect against future attacks from quantum computers, so it turned to mathematical proofs to make sure the code works correctly before wider rollout.

Quantum acoustics devices may have applications in quantum computers and biophysics.

When running an AI model through a quantum computer, scientists have increased accuracy by only adding a relatively small number of parameters.
