- Quantum technology
Quantum technology is a new field of physics and engineering, which transitions some of the stranger features of
quantum mechanics, especially quantum entanglement, into practical applications such as quantum computing, quantum cryptography, quantum metrology, quantum sensing, and quantum imaging.
The field of quantum technology was first outlined in a
1997book by Gerard J. Milburn, [ [http://www.physics.uq.edu.au/people/milburn/books/Schr_Mach.html "Schrödinger's Machines"] , G.J.Milburn, W H Freeman & Co. (1997)] which was then followed by a 2003article by Jonathan P. Dowlingand Gerard J. Milburn, [" [http://journals.royalsociety.org/content/bdm1frlb9tfmr3ar/ Quantum Technology: The Second Quantum Revolution] ,"J.P.Dowling and G.J.Milburn, Phil. Trans. R. Soc. A 361, 3655 (2003)] [" [http://arxiv.org/abs/quant-ph/0206091 Quantum Technology: The Second Quantum Revolution] ," J.P.Dowling and G.J.Milburn, arXiv:quant-ph/0206091v1] as well as a 2003article by David Deutsch. [" [http://www.qubit.org/people/david/structure/Documents/Research%20Papers/PPQT.pdf Physics, Philosophy, and Quantum Technology] ," D.Deutsch in the Proceedings of the Sixth International Conference on Quantum Communication, Measurement and Computing, Shapiro, J.H. and Hirota, O., Eds. (Rinton Press, Princeton, NJ. 2003)] The field of quantum technology has benefited immensely from the influx of new ideas from the field of quantum information processing, particularly quantum computing. Disparate areas of quantum physics, such as quantum optics, atom optics, quantum electronics, and quantum nanomechanical devices, have been unified under the search for a quantum computerand given a common language, that of quantum informationtheory.
In concise terms, a
quantum computerwill someday be a giant quantum interferometerconsisting of millions of quantum entangledparticles, which will solve mathematical problems not solvable on any classical computer. This feat itself is to be one of the crowning jewels of quantum technology. However, once such a machine exists, it will be put to work on other tasks related to imaging, sensing, clock synchronization, and precision measurement.
