متن کاملPhase-space characterization of complexity in quantum many-body dynamics.
We propose a phase-space Wigner harmonics entropy measure for many-body quantum dynamical complexity. This measure, which reduces to the well-known measure of complexity in classical systems and which is valid for both pure and mixed states in single-particle and many-body systems, takes into account the combined role of chaos and entanglement in the realm of quantum mechanics. The effectivenes...
متن کاملQuantum Computation, Complexity, and Many-body Physics
By taking advantage of the laws of physics it is possible to revolutionize the way we communicate (transmit), process or even store information. It is now known that quantum computers, or computers built from quantum mechanical elements, provide new resources to solve certain problems and perform certain tasks more efficiently than today’s conventional computers. However, on the road to a compl...

متن کاملMany-body quantum dynamics of polarization squeezing in optical fibers.
We report new experiments that test quantum dynamical predictions of polarization squeezing for ultrashort photonic pulses in a birefringent fiber, including all relevant dissipative effects. This exponentially complex many-body problem is solved by means of a stochastic phase-space method. The squeezing is calculated and compared to experimental data, resulting in excellent quantitative agreem...
