The quantum-confined Stark effect (QCSE) describes the effect of an external electric field upon the light absorption spectrum or emission spectrum of a quantum well (QW). In the absence of an external electric field, electrons and holes within the quantum well may only occupy states within a discrete set of energy subbands.
The current state of quantum computing [1] is referred to as the noisy intermediate-scale quantum (NISQ) era, [2] [3] characterized by quantum processors containing up to 1,000 qubits which are not advanced enough yet for fault-tolerance or large enough to achieve quantum advantage.
This list contains quantum processors, also known as quantum processing units (QPUs).Some devices listed below have only been announced at press conferences so far, with no actual demonstrations or scientific publications characterizing the performance.

A quality control system (QCS) refers to a system used to measure and control the quality of moving sheet processes on-line as in the paper produced by a paper machine. . Generally, a control system is concerned with measurement and control of one or multiple properties in time in a single dimen
Rigetti Computing was founded in 2013 by Chad Rigetti, a physicist with a background in quantum computers from IBM, and studied under Michel Devoret. [2] [3] The company emerged from startup incubator Y Combinator in 2014 as a so-called "spaceshot" company.
Here are some examples of one-dimensional cluster states (d=1), for =,,, where is the number of qubits.We take = for all , which means the cluster state is the unique simultaneous eigenstate that has corresponding eigenvalue 1 under all correlation operators.
Perfluoro(2-methyl-3-pentanone) is a fluorinated ketone with the structural formula CF 3 CF 2 C(=O)CF(CF 3) 2, a fully-fluorinated analog of ethyl isopropyl ketone. It is used as an electronics coolant liquid and fire protection fluid sold commercially by 3M under brand names such as Novec 1230 , Novec 649 , and FK-5-1-12 .
