4-12-96. Science: "Error-Correcting Codes Keeps Quantum Computers on Track" Commentary by Barry Cipra on Peter Shor's error-correction scheme for quantum systems (published last year in Phys Rev A) and his subsequent work with Rob Calderbank at AT&T Research on "quantum analogs of other more powerful codes that can correct multiple errors in long strings of bits." And cites work of others who are following Shor's lead -- Seth Lloyd at MIT, IBM, LANL, Oxford: "Quantum computers may be getting closer to reality." ERR_not
