Approach to ergodicity in quantum wave functions
... In the semiclassical limit, quantum wavefunctions (or their corresponding phase space counterparts, such as the associated Wigner functions) are supported by classically invariant structures [1,2]. In integrable systems they are concentrated on tori [3,4] and in chaotic systems they tend to spread o ...

Continuous Time Quantum Monte Carlo method for fermions
... the non-Hamiltonian systems we also did not observe any indications of the divergence. The crucial point of the proof is the finiteness of the number of states in the system. This is a particular peculiarity of fermions. For bosons, on other hand, one deals with a Hilbert space of an infinite dimens ...

Adiabatic Quantum Computation is Equivalent to Standard Quantum Computation Dorit Aharonov
... is polynomially equivalent to the standard model of quantum computation. This shows that universal quantum computation can be fully studied and implemented in the adiabatic framework, and so adiabatic computation can be thought of as an alternative model to quantum computation. We also show that a s ...
