All the big-brain mathematicians/cryptographers I know are extremely skeptical about quantum computing ever becoming a reality. The problems of stability are also exponential, and so getting from a few dozen/hundred qbits to something big enough to be reasonable may be essentially impossible.
Of course some breakthrough could happen; so could room-temperature superconductors, anti-gravity, or a cure for cancer. Tomorrow-or never. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
