Study of photons in quantum computing reveals that when photons collide, they create vortices

Vortices are a common physical phenomenon. You find them in the structure of galaxies, tornadoes and hurricanes, as well as in a cup of tea, or water as it drains from the bathtub.

Saturday Citations: Listening to bird dreams, securing qubits, imagining impossible billiards

It's Saturday, which means that in a universe where the arrow of time moves backward, people have to go to work tomorrow. In such a hypothetical universe, Garfield hates Fridays—tough to imagine. This week, we looked at ...

Nonvolatile quantum memory: Discovery points path to flash-like memory for storing qubits

Rice University physicists have discovered a phase-changing quantum material—and a method for finding more like it—that could potentially be used to create flash-like memory capable of storing quantum bits of information, ...
