量子态约化的高效模拟

Efficient Simulation of Quantum State Reduction

Dorje C. Brody, Lane P. Hughston

摘要:

薛定谔方程的基于能量的随机延拓是Hilbert空间上一个相当特殊的非线性随机微分方程,它只包含一个自由参数,对于模拟量子态约化现象非常有用.在这里,我们构造了一个一般的封闭形式的解决方案,对于任何给定的初始条件,在一个随机变量表示的终端值的能量和一个独立的布朗运动。该解本质上是代数性质的,不涉及积分,因此适合作为复杂系统中状态约简的有效仿真研究的基础。

英文摘要:

The energy-based stochastic extension of the Schrodinger equation is a rather special nonlinear stochastic differential equation on Hilbert space, involving a single free parameter, that has been shown to be very useful for modelling the phenomenon of quantum state reduction. Here we construct a general closed form solution to this equation, for any given initial condition, in terms of a random variable representing the terminal value of the energy and an independent Brownian motion. The solution is essentially algebraic in character, involving no integration, and is thus suitable as a basis for efficient simulation studies of state reduction in complex systems.
