Quantum Computers Can Search Rapidly by Using Almost
... Since all quantum mechanical operations are unitary, this means that almost any quantum mechanical system can be used—all that is needed is a valid quantum mechanical operation and a way of selectively inverting the phase of states. Meaningful computation can hence be carried out on the basis of uni ...

... The second approach is the one in which the leads (long, but finite) are already coupled with the sample, and at t = −∞ the full system is in a Gibbs equilibrium state at a given temperature and chemical potential. Then we adiabatically turn on a potential bias between the leads, modeling in this w ...

Algorithmic complexity of quantum states
... Classical algorithmic complexity [3] was first introduced to give an answer to the question: “is the classical string ω N = ωi1 ωi2 ωiN random?”. The definition is based on the concept of algorithmic reproducibility of a sequence: The algorithmic complexity KCl of a string ω N is the length of the s ...
