In an important step forward in the quest to build a quantum computer using silicon-based hardware, researchers have succeeded in making possible the exchange of information between two qubits located relatively far apart – about the length of a grain of rice, which is a considerable distance on a computer chip. Connecting two silicon qubits across this distance makes possible new and more complex silicon-based quantum computer circuits.

Imagine a world where people could only talk to their next-door ne...

Active galactic nuclei (AGN) are supermassive black holes at the centers of galaxies that are accreting material. These AGN emit jets of charged particles that move at speeds close to that of light, transporting huge amounts of energy away from the central black hole region and radiating across the electromagnetic spectrum...

Scientists at Tokyo Institute of Technology (Tokyo Tech) explore a new material combination that sets the stage for magnetic random access memories, which rely on spin – an intrinsic property of electrons – and could outperform current storage devices...

Grizzly bears spend many months in hibernation, but their muscles do not suffer from the lack of movement. In the journal Scientific Reports, a team led by Michael Gotthardt reports on how they manage to do this. The grizzly bears’ strategy could help prevent muscle atrophy in humans as well.

A grizzly bear only knows three seasons during the year. Its time of activity starts between March and May. Around September the bear begins to eat large quantities of food. And sometime between November and January, it falls into hibernation...
