... Shor’s algorithm (and Grover’s, searching an unstructured data base of size N with ~√N operations rather than ~ N/2) is rather specialized. Would a quantum computer also be useful for more general problems, such as optimization problems, i.e. minimizing a function of N variables with constraints? Of ...

A violation of the uncertainty principle implies a violation of the
... We would like to emphasize that thermodynamical cycles have been useful before to examine foundational questions and our cycle is indeed similar to the ones given in refs 25–28. Our contribution lies in the insight that a violation of uncertainty relation allows for the construction of a similar (bu ...

The Power of Quantum Advice
... Suppose a finite automaton M is trying to decide whether a coin has p=½ or p=½+. Then even if it can flip the coin an unlimited number of times, M needs (1/) states to succeed with probability (say) 2/3. This result seems to imply PSPACE/coinPSPACE/poly, since we could take the first poly(n) bit ...

A Quantum Algorithm for Finding a Hamilton Circuit
... Hamilton circuit which we gave in Sec. 2. If it satises the properties, then D is a Hamilton circuit of G, otherwise it is not. Obviously this step can be completed in polynomial steps. The p mtotal number of steps is the order of (11mn ; 3m) 2 if we use Grover's algorithm in searching the solution ...
