Quantum timekeeping is supposed to be the ultimate in efficiency, with tiny devices that tick using the rules of quantum mechanics instead of swinging pendulums or vibrating quartz. Yet new work on a ...
A specially tweaked classical computer system has just solved a physics problem so complex it was thought to be impossible without a quantum computer. The problem is the simulation of what are called ...

Physicists in Japan just built a way to instantly read one of the strangest quantum states — a shortcut toward faster quantum networks and teleportation
A team at Nihon University has figured out how to read entangled quantum states across an entire many-body system without ...
Quantum technologies—devices that operate according to quantum mechanical principles—promise to bring users some groundbreaking innovations in whichever context they appear. Ironically, the same ...
Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...
What use is a quantum computer? Perhaps both more and less than you think, according to quantum computing expert Shayan Majidy ...
Chalmers engineers built a pulse-driven qubit amplifier that’s ten times more efficient, stays cool, and safeguards quantum states—key for bigger, better quantum machines. Researchers at Chalmers ...
The steady tick of a clock usually feels simple and dependable. Something swings or vibrates in a controlled rhythm and marks the passing of each moment. What you rarely notice is the hidden cost ...
Graphic illustrating the difference in energy between running a quantum clock (left: a single electron hopping between two nanoscale regions) and reading the ticks of the clock (right). The energy ...
