Realisation of a programmable two-qubit quantum processor
... Computers are useful because they are versatile. Changing the problem to be solved amounts to reconfiguring inputs to the processor, that is, to reprogramming it. In a classical computer, a program is ultimately decomposed into sequences of operations implemented with logic gates. The explosion of i ...

Each path would be assigned a complex amplitude (basically some product of r, t), and by adding all the relevant paths together, we would get ...

Inequivalence of pure state ensembles for open quantum systems
... such ensembles are not physically realizable (PR). However, there are other stationary ensembles that are PR. The existence, for a given system, of two non-empty classes of stationary ensembles, those that are PR and those that are not, constitutes a preferred ensemble fact (PE-fact). Note that this ...
