The QuTech researchers, led by Menno Veldhorst, adopted a “shared-control” approach inspired by classical random-access computing architectures in which millions of transistors are operated with a ...

These semiconducting sheets form an egg-carton-like array in which the “pockets” are quantum dots that can be controlled using light, and they could be used to make ultralow-energy switches. Led by ...

Ordered arrays of charge-controllable quantum dots can find application in computing memory as well as light-emitting devices (eg, low-energy TV or smartphone screens).

"We were initially trying to tune up and calibrate the exchange interaction between all the neighboring spins in a 4x2 quantum dot array, loaded with one spin per dot," Lieven Vandersypen, senior ...

But typical quantum dots are only a few atoms across—they aren't on a usable scale. As a solution, Deng's team created an array of quantum dots that contribute to the nonlinearity all at once.
