The second law of thermodynamics is among the most sacred in all of science, but it has always rested on 19th century arguments about probability. New arguments trace its true source to the flows of quantum information.
So-called topological quantum computing would avoid many of the problems that stand in the way of full-scale quantum computers. But high-profile missteps have led some experts to question whether the field is fooling itself.
The molecular signaling systems of complex cells are nothing like simple electronic circuits. The logic governing their operation is riotously complex — but it has advantages.
By showing that even large objects can exhibit bizarre quantum behaviors, physicists hope to illuminate the mystery of quantum collapse, identify the quantum nature of gravity, and perhaps even make Schrödinger’s cat a reality.
A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.
Three experiments have vetted quantum Darwinism, a theory that explains how quantum possibilities can give rise to objective, classical reality.
A recent test has confirmed the predictions of quantum trajectory theory.
