Quantum speedup of classical mixing processes ∗
It is known that repeated measurements performed at uniformly random times enable the continuous-time quantum walk on a finite set S (using a stochastic transition matrix P as the time-independent Hamiltonian) to sample almost uniformly from S provided that P does. Here we show that the same phenomenon holds for other (discrete-time) walk variants and more general measurements types, then focus...

متن کاملMixing Quantum and Classical Mechanics
Using a group theoretical approach we derive an equation of motion for a mixed quantum-classical system. The quantum-classical bracket entering the equation preserves the Lie algebra structure of quantum and classical mechanics: The bracket is antisymmetric and satisfies the Jacobi identity, and, therefore, leads to a natural description of interaction between quantum and classical degrees of f...
متن کاملAbsence of classical and quantum mixing.
Brief Reports are accounts of completed research which do not warrant regular articles or the priority handling given to Rapid Communications; however, the same standards of scientific quality apply. (Addenda are included in Brief Reports.) A Brief Report may be no longer than four printed pages and must be accompanied by an abstract. The same publication schedule as for regular articles is fol...
متن کاملImpediments to mixing classical and quantum dynamics
The dynamics of systems composed of a classical sector plus a quantum sector is studied. We show that, even in the simplest cases, ~i! the existence of a consistent canonical description for such mixed systems is incompatible with very basic requirements related to the time evolution of the two sectors when they are decoupled, ~ii! the classical sector cannot inherit quantum fluctuations from t...
