Physicists Observe ‘Unobservable’ Quantum Phase Transition
Measurement and entanglement both have a “spooky” nonlocal flavor to them. Now physicists are harnessing that nonlocality to probe the spread of quantum information and control it.
New Calculations Show How to Escape Hawking’s Black Hole Paradox
Inside of a black hole, the two theoretical pillars of 20th-century physics appear to clash. Now a group of young physicists think they have resolved the conflict by appealing to the central pillar of the new century — the physics of quantum information.
In New Paradox, Black Holes Appear to Evade Heat Death
The puzzling behavior of black hole interiors has led researchers to propose a new physical law: the second law of quantum complexity.
Physicists Create Elusive Particles That Remember Their Pasts
In two landmark experiments, researchers used quantum processors to engineer exotic particles that have captivated physicists for decades. The work is a step toward crash-proof quantum computers.
Black Holes Will Eventually Destroy All Quantum States, Researchers Argue
New calculations suggest that the event horizons around black holes will ‘decohere’ quantum possibilities — even those that are far away.
Physicists Use Quantum Mechanics to Pull Energy out of Nothing
The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works.
Physicists Create a Holographic Wormhole Using a Quantum Computer
The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.
