... the best known upper bound for k-SAT (see below). Schöning’s algorithm was derandomized in [6]. In Schöning’s algorithm, there are N ∼ (2 − 2/k)n results of different runs of S, and we look for a result in which √ the input formula F is satisfied. Grover’s algorithm enables us to find this result ...

We have shown the most general case of Alice sending a qubit to the Bobs, but a special case would be where Alice could be a factory of pure states. MRAP could be used to send these ...

... that any information (which-path or both-path) one can infer from photon 2 must be at least 7.7 ns later than the registration of photon 1. Compared to the 1 ns response time of the detectors, a 2.3 m delay is thus sufficient for the “delayed erasure.” Although there is an arbitrariness in the time ...
