Chaos and Lyapunov exponents in classical and quantal distribution dynamics
We analytically establish the role of a spectrum of Lyapunov exponents in the evolution of phase-space distributions r(p ,q). Of particular interest is l2 , an exponent that quantifies the rate at which chaotically evolving distributions acquire structure at increasingly smaller scales and is generally larger than the maximal Lyapunov exponent l for trajectories. The approach is trajectory inde...
متن کاملQuantum-locked key distribution at nearly the classical capacity rate.
Quantum data locking is a protocol that allows for a small secret key to (un)lock an exponentially larger amount of information, hence yielding the strongest violation of the classical one-time pad encryption in the quantum setting. This violation mirrors a large gap existing between two security criteria for quantum cryptography quantified by two entropic quantities: the Holevo information and...
متن کاملClassical bifurcation at the transition from Rabi to Josephson dynamics.
We report on the experimental demonstration of the internal bosonic Josephson effect in a rubidium spinor Bose-Einstein condensate. The measurement of the full time dynamics in phase space allows the characterization of the theoretically predicted π-phase modes and quantitatively confirms analytical predictions, revealing a classical bifurcation. Our results suggest that this system is a model ...
متن کاملFrom classical to quantum dynamics at Rokhsar-Kivelson points
For any classical statistical-mechanics model with a discrete state space, and endowed with a dynamics satisfying detailed balance, it is possible to generalize the Rokhsar-Kivelson point for the quantum dimer model. That is, a quantum Hamiltonian can be constructed (on the same state space), such that the ground state wavefunction coincides with the classical equilibrium distribution. Furtherm...
متن کاملA New Modification in the Classical Laplace Distribution
‎Several modifications of the Laplace distribution have been introduced and applied in various fields up to this day‎. ‎In this paper‎, ‎we introduce a modified symmetric version of the classical Laplace distribution‎. ‎We provide a comprehensive theoretical description of this distribution‎. ‎In particular‎, ‎we derive the formulas for th...
