Researchers aiming to create a secure quantum version of the internet need a device called a quantum repeater, which doesn't yet exist - but now two teams say they are well on the way to building one
A quantum bit inspired by Schrödinger’s cat can resist making errors for an unprecedentedly long time, which makes it a candidate for building less error-prone quantum computers
A recent paper of Kra, Moreira, Richter, and Robertson established the following theorem, resolving a question of Erdös. Given a discrete amenable group , and a subset of , we define the Banach density of to be the quantity where the supremum is over all Følner sequences of . Given a set in , we […]
Quantum computers are Blue versions of classical computers [1] [2] [3][4] Blue or grey abstract patterns [1] [2][3][4][5][6] A bunch of connectors [1][2] Blurred out chips [1] What goes inside the dilution fridge [1][2][3] Closed dilution fridges [1] Part of a flag [1] A button near the enter key [1] Icy cold really big atoms … Continue reading "Quantum Computers Are…"
The first progress prize competition for the AI Mathematical Olympiad has now launched. (Disclosure: I am on the advisory committee for the prize.) This is a competition in which contestants submit an AI model which, after the submissions deadline on June 27, will be tested (on a fixed computational resource, without internet access) on a […]
