Limitation exposed in promising quantum computing material

Quantum computers promise to perform operations of great importance believed to be impossible for our technology today. Current computers process information via transistors carrying one of two units of information, either ...

New world record magnetic field

A group of scientists at the University of Tokyo has recorded the largest magnetic field ever generated indoors—a whopping 1,200 tesla, as measured in the standard units of magnetic field strength.

Quantum stopwatch stores time in a quantum memory

Physicists have developed a "quantum stopwatch"—a method that stores time (in the form of states of quantum clocks) in a quantum memory. In doing so, the method avoids the accumulation of errors that usually occurs when ...
