Ah! it always comes down to cyber-money ;-)

Some of them can be failed, but only in theory. Well, the last time I readon on this, but the filed is exploding. I guess that *classical* teleportation will needs quantum encryption too, if you want avoid to be reconstituted by some Eve (by some Eavesdroppers). I would not say "yes" to a "doctor" without some guaranties my "Gödel number" is enough secure. I predict that the amount of digital communication used in encryption will ever go up. Already bitcoin is very demanding, and virtual money might become a danger for the climate. Some estimates that the Internet is responsible already of 15% of the mundial pollution, ... Now, Quantum computations will have many applications different from encryption. To make the MW valid (original goal of Deutsch), to "find a needle in a stack", to factorize big numbers (with other goal than encryption (say), etc. but the main non-encryption goal will be to simulated nature's phenomena, from protein foldings to black hole, to big-bang(s), etc. Bruno On 01 Dec 2017, at 01:05, spudboy100 via Everything List wrote: Any potential for this technology to go beyond Bitcoin or encryption applications, JC? Specifically, the impact upon technological innovation. Or do you feel, this is a pipe-dream, a bridge, too far? -----Original Message----- From: John Clark <johnkcl...@gmail.com> To: everything-list <everything-list@googlegroups.com> Sent: Thu, Nov 30, 2017 10:20 am Subject: Quantum Supremacy For the first time a Quantum Computer has solved a problem that a conventional computer can not, actually 2 different Quantum Computers did and there is a paper from each team in the issue of the journal Nature that came out yesterday: https://www.nature.com/articles/nature24654.epdf?referrer_access_token=d5OIRgRXjhov_Y7aUYicHdRgN0jAjWel9jnR3ZoTv0O2y_BZ5CPS-KH0aejio0CrBO8pCtA0Hw4GFFcyLIGq_9sLyItmGlAGgcpoZyLC8y6KSXTgCvy7v1QisLsYnG7vqi0w-vnf5I6-odil-i4Ggo4QUUcQBWJIcfy58N7x-D6YsD_nU4U1ytVuVTPC_9DiOvGaqFmBfRv224xNWopYo0YSPYwYmZ6NRvXUvTz9IjU%3D&tracking_referrer=www.livescience.com /www.nature.com/articles/nature24622.epdf?referrer_access_token=dgXGNTysT8EwhOOZ9lOtQtRgN0jAjWel9jnR3ZoTv0MQ8a6_YgG4UfcW2SwV0yyUTLJhfJnff5uaj_no78zD6rP8nmDWU7noJKpPvMWclA9w0aheS0c6M6vehI9x_Y8JbfCt86YmnfvcXZxYxSOKVlOHn9Fb-nJl6gLqSwV3gVD4ALGMk31HzU-p36zd4sOlyMHyN2g8I9iV1b0Z70zl6VRmdR2KbTP55RsXB2mA2cQ%3D&tracking_referrer=www.livescience.com They used their computers to simulate a quantum system, the particular problem they solved is not very useful but the implications are enormous, it proves once and for all that a practical quantum computer that you can actually build can solve problems that a conventional computer can't. If I place 20 magnetized atoms in a lattice and then move one of those atoms how will the entire array move in response? A good home computer could solve that problem but the difficulty increases exponentially as the number of atoms increases, when you get to about 50 atoms even the largest supercomputer on Earth starts to beg for mercy, but in the new reports one quantum computer solved the 51 atom problem and the other solved 53. The mechanical details of the 2 machines are different, one used very tightly focused LASER beams and rubidium atoms and the other used electrically charged ytterbium ions, but they both got the job done. None of this is a threat to bitcoin....YET. But the clock is ticking. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
