Quantum Technology  

In General > s.a. microscopes; technology [molecular devices].
@ Books and reviews: Bardeen PT(90)dec [macroscopic quantum phenomena]; Perkowitz ThSc(95)jan; Milburn 97; Dowling & Milburn qp/02; Pavicic 06 [computation and communication].

Quantum Dots
* Idea: Structures in which electrons are confined in all three dim's, so that energies are quantized (like the square well!). Luminescence from single, nm-sized InAs dots excited by a He-Ne laser has been observed.
* Production: Can be made litographically, by etching with e beams, or by "growing".
* Applications: Read and write data with bursts of laser light.

Quantum Wires
* Idea: Electrons restricted to 1D motion.

Quantum Wells
* 1996: Already at work in devices.
* Idea: Semiconductor sandwiches where e's are confined to a plane.

Quantum Cryptography > s.a. [Cryptography]; formulations of quantum mechanics.
* 2000: Three groups show use of entangled photons to create secret codes.

Teleportation
* Idea: Transporting the quantum state of a system between 2 locations without moving in the intervening space; From quantum 'no-cloning' theorem, possible only if the original is destroyed; Entanglement is a central concept.
* History: 1993, Proposed, Bennett et al; 1997–1998, Partial implementations, Bouwmeester et al & Boschi et al; 2005, Over the last few years, researchers have successfully teleported beams of light across a laboratory bench and the quantum state of a trapped Ca ion to another Ca ion has been teleported in a controlled way.
