This defect is the cause of “spurious dots” within the qubit layer, and is a major source of yield loss in QD arrays. This means that it causes many defects.

If the exciton is confined to a quantum dot, however, as in this new work, it is impossible to add a second identical exciton to the same quantum dot, explains Deng. To do this, a higher energy photon ...

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.

In their technique, they made a quantum chip hosting a 16-quantum-dot system in a 4×4 chessboard-like array. “The quantum dots of the array are addressed collectively using a few shared control ...

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).

(Nanowerk News) A new path toward sending and receiving information with single photons of light has been discovered by an international team of researchers led by the University of Michigan. Their ...

Quantum dot arrays require monodisperse components in order to prevent anomalous properties from occurring, but many vary in their structure. The ability to control the width of electronic barriers is ...

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.

Dot Hill is first to market in delivering 8Gb Fibre Channel/1Gb iSCSI hybrid arrays in a compact, entry level 2U form factor (3930 for large form factor 3.5-inch disks, and 3920 for small form factor ...
