Unruh效应对量子存储下熵不确定关系的影响
The effect of Unruh effect for quantum-memory-assisted entropic uncertainty relation
摘要
Abstract
Uncertainty relations provide constraints on how well the outcomes of incompatible measurements can be predicted and fundamental to our understanding of quantum theory.They have practical applications in cryptography and witnessing entanglement.Here,the authors explored how Unruh effect would affect quantum-memory-assisted entropic uncertainty relation (QMA-EUR) for a pair of maximally entangled Unruh-Dewitt detectors when one of them was accelerated and coupled to a massless scalar field.The result showed that while the amount of uncertainty was increased in low accelerations,it was reduced in higher accelerations and had a nontrivial behavior acquiring its maximum value at a certain acceleration.The mechanism of these phenomena were explored by using two dissimilar methods.关键词
