基于量子相干的波粒二象性关系及其验证方案

Wave-Particle Duality Relation Based on Quantum Coherence and Its Test Scheme

提出了一个验证基于量子相干的波粒二象性关系的方案。通过φ→π→π/2脉冲序列,构造出原子干涉仪。对于初始处于基态的原子,经过原子干涉仪的作用,可以计算出量化波动性的量子相干C和量化粒子性的路径可预测度P,研究发现C和P满足波粒二象性关系C2+P2=1。因此,在原子干涉仪中验证了基于量子相干的波粒二象性关系。

A scheme for testing wave-particle duality relation based on quantum coherence is proposed. An atomic interferometer is constructed through φ→π→π/2 pulse sequence. Assuming an atom is initially in the ground state,after the atomic interferometer,its quantum coherence C quantized wave’s property and path predictability P quantized particle’s property can be calculated. It can be found that C and P satisfy wave-particle duality relation. Therefore,wave-particle duality relation based on quantum coherence is verified in atomic interferometers.
