Quantum Optics VII Conference Program
... Fifty years ago, John Bell laid down the foundation of the employment of many of us at this conference. His theorem not only made a testable prediction for quantum mechanics, but also provided a horizon which delineated quantum from post-quantum theories. In this talk I will shine some light on an o ...

Decoherence and open quantum systems
... In practice, any realistic physical system has to be regarded as a system coupled to an uncontrollable environment which influences it in a nonnegligible way. Therefore the theory of open quantum systems plays an important role in many different applications in the field of quantum mechanics, where ...

... 2 Trjρ − τj. For one-qubit states ρ, the trace distance of coherence equals (half) the l1 norm of coherence [48,53], but this equivalence is not valid for higher dimensional systems, and it is still unknown whether CTr obeys requirement (ii b) in general. Frozen coherence: One qubit.—We now analyze ...

For the approximation of the wave function of the electronic structure of an atomic or molecular system, any method chosen will have to compromise between the demanded accuracy on the one hand and the high computational complexity of the task on the other. While density functional theory (DFT)[1] an ...
