... Is it impossible to understand anything about this machine so long as we do not take it to pieces? Surely not, and the principle of the conservation of energy suffices to deduce the most interesting point. Suppose we learn that the final wheel turns ten times less quickly than the initial wheel; we ...

Integration via a Quantum Information Processor
... Quantum computers are devices made up of two level quantum systems or qubits that can process information in a way that preserves quantum coherence. Unlike a classical bit, a qubit can be in a superposition of states 0 and 1 at the same time. In addition, quantum bits may become entangled, that is, ...

but quantum computing is in its infancy.
... It turns out that classical computers are not very good at factoring large numbers, a weakness that has long been exploited by cryptographers to safeguard data on the Internet. It is easy to multiply two prime numbers in order to produce a much larger number, but it turns out to be horrendously dif ...

An Invitation to Quantum Complexity Theory
... Contrary to almost every popular article ever written on the subject, most of us think the answer is no For “generic” combinatorial optimization problems, the situation seems similar to that of black-box model—where you only get the quadratic speedup of Grover’s algorithm, not an exponential speedup ...
