Dissipative decoherence in the Grover algorithm
... by the random matrix theory [10]. The two former classes are related to unitary errors. However, there is also the third class which corresponds to the case of nonunitary errors typical to the case of dissipative decoherence. This type of errors has been studied recently for the quantum baker map [1 ...

Quantum phase transitions in atomic gases and
... For smaller J, there can be a confinementdeconfinement transition at which the S=1/2 spinons are liberated: these are neutral, S=1/2 quasiparticles The gap to all excitations with non-zero S remains finite across this transition, but the gap to spin singlet excitations vanishes. There is no local or ...
