EXPONENTIAL SEPARATION OF QUANTUM AND CLASSICAL
... input. By the birthday paradox, with high probability, Bob can recover the value of at least one of his matching pairs from Alice’s message. Remarkably, this problem remains easy for quantum one-way communication. Alice only needs to send a uniform superposition of her string x, hence communicating ...

... many-body origin of Ramsey fringe decay. In the following, we argue that unambiguous signatures of the multimode decoherence are found in the full distribution function of the Ramsey fringe amplitudes. Such distribution functions should be accessible in experiments with 1D quasicondensates realized ...

Spin Transverse Force on Spin Current in an Electric Field
... This is the quantum mechanical analogue of Newton’s second law. Of course we should notice that this is just an operator equation. The uncertainty relationship tells us that the position and momentum cannot be measured simultaneously, and there is no concept of force in quantum mechanics. To see the ...

A crucial property of the NP problem class is that there exist problem types which can be reduced to any other problem type in NP (i.e. we can restate any problem in NP as an ex ...
