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.
A New Theory for Systems That Defy Newton’s Third Law
In nonreciprocal systems, where Newton’s third law falls apart, “exceptional points” are helping researchers understand phase transitions and possibly other phenomena.
Major Quantum Computing Strategy Suffers Serious Setbacks
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.
Physicists Create a Bizarre ‘Wigner Crystal’ Made Purely of Electrons
The unambiguous discovery of a Wigner crystal relied on a novel technique for probing the insides of complex materials.
The ‘Weirdest’ Matter, Made of Partial Particles, Defies Description
Theorists are in a frenzy over “fractons,” bizarre, but potentially useful, hypothetical particles that can only move in combination with one another.
‘Milestone’ Evidence for Anyons, a Third Kingdom of Particles
Anyons don’t fit into either of the two known particle kingdoms. To find them, physicists had to erase the third dimension.
