Quantum Chaos
... What are the appropriate quantum observables to detect the regular or chaotic classical behaviour of the system? More precisely, how does the regular or chaotic classical behaviour translate in the energy levels and eigenstates of the (bound) system? For an open system, in the decay rates, in the ...

Efficient generation of a maximally entangled state by
... characterized by a success probability strictly less than 1. The primary motivation of the present work is to pursue a scheme that would allow one to reach the target state with probability 1, or at least with probability arbitrarily close to 1, independently of the initial conditions. We have been ...

Quantum State Transfer via Noisy Photonic and Phononic Waveguides
... i.e., the operator of the first cavity mode at initial time ti is mapped to the second cavity mode at final time tf , with no admixture from bR ðtÞ [26]. In other words, an arbitrary photon superposition state prepared initially in the first cavity can be faithfully transferred to the second distant ...

The upcoming radical technological shift towards quantum computers promises efficient processing of certain computational tasks which are intractable with classical computer technology. One obstacle hindering the widespread use of ...
Mathematical structure of magnons in quantum

The result is that the magnon canonical variables are nothing but fluctuation operators, whose mathematical structure is developed in [9, 10]. We rigorously perform the infinite spin limit, and p ...

We begin our study of tunneling by investigating as to why tunneling is exclusively a quantum phenomena and does not have a classical counterpart. .[1] ...
