When two-dimensional electron systems are subjected to magnetic fields at low temperatures, they can exhibit interesting ...

In the fractional quantum Hall effect, these steps become even more peculiar, increasing by only fractional amounts—carrying ...

This "fractional quantum Hall effect" is a counterintuitive quirk of quantum mechanics, Stormer explained in his Nobel Lecture: "It implies that many electrons, acting in concert, can create new ...

By 2019, the team achieved 18-kilometre quantum entanglement distribution, followed by hundred-plus kilometre links a few years later. Today, their entanglement testbed runs from Long Island to ...
