Computer Science Proof Unveils Unexpected Form of Entanglement
Three computer scientists have posted a proof of the NLTS conjecture, showing that systems of entangled particles can remain difficult to analyze even away from extremes.
Cryptographers Achieve Perfect Secrecy With Imperfect Devices
For the first time, experiments demonstrate the possibility of sharing secrets with perfect privacy — even when the devices used to share them cannot be trusted.
Computer Scientists Eliminate Pesky Quantum Computations
For years, intermediate measurements made it hard to quantify the complexity of quantum algorithms. New work establishes that those measurements aren’t necessary after all.
Euler’s 243-Year-Old ‘Impossible’ Puzzle Gets a Quantum Solution
A surprising new solution to Leonhard Euler’s famous “36 officers puzzle” offers a novel way of encoding quantum information.
Quantum Simulators Create a Totally New Phase of Matter
One of the first goals of quantum computing has been to recreate bizarre quantum systems that can’t be studied in an ordinary computer. A dark-horse quantum simulator has now done just that.
