Quantum Technology  

In General > s.a. microscopes; technology [molecular devices].
* Idea: 2019, "The second quantum revolution is in full swing and promises to revolutionize areas such as computation, communication, metrology, and imaging".
@ Books and reviews: Bardeen PT(90)dec [macroscopic quantum phenomena]; Perkowitz ThSc(95)jan; Milburn 97; Dowling & Milburn qp/02; Erhard et al a1911 [technological developments with entangled photonic systems].
@ Related topics: Hogg & Chase qp/96-proc [smart matter]; Benioff PRA(98)qp [robots]; Boto et al PRL(00)qp/99 [etching, entangled gammas]; Blencowe PRP(04) [quantum electromechanical systems]; Hillmer & Kwiat SA(07)may [quantum eraser]; Hillery & Buzek CP(09) [quantum machines]; Yang et al PRS-a1804 [quantum stopwatch]; Siddiqi et al Phys(20) [quantum literacy]; Hull et al a2012 [quantum computing and quantum money, for economists]; Laucht et al a2101-in [quantum nanotechnologies, roadmap]; > s.a. macroscopic quantum systems.

Quantum Dots
* Idea: Structures in which electrons are confined in all three dimensions, so that energies are quantized (like the square well!); Essentially tiny pools of electrons in semiconductors that act as artificial atoms; Luminescence from single, nm-sized InAs dots excited by a He-Ne laser has been observed.
* Production: They can be made litographically, by etching with electron beams, or by "growing".
* Applications: Read and write data with bursts of laser light; > s.a. technology [solar].

Other Quantum Technology > s.a. quantum communication [including teleportation]; quantum computers; quantum information.
* Quantum cloning: 1982, Wootters-Zurek 'no-cloning' theorem, stating that it is possible only with some error.
* Quantum wells: Semiconductor sandwiches where electrons are confined to a plane; 1996, Already at work in devices.
* Quantum wires: Electrons restricted to 1D motion.
