如何保护波函数的解释不受保护性测量的影响

How to protect the interpretation of the wave function against protective measurements

Jos Uffink

摘要:

Aharonov、Anandan和Vaidman提出了一种称为保护措施的新型程序。这些作者认为,保护性测量允许确定单个量子系统的任意可观测量,并声称这有利于对量子态的现实解释。本文证明了只有与系统哈密顿量对易的观测量才能被保护性地测量。有人认为,这种限制保存的连贯性的替代解释。

英文摘要:

A new type of procedures, called protective measurements, has been proposed by Aharonov, Anandan and Vaidman. These authors argue that a protective measurement allows the determination of arbitrary observables of a single quantum system and claim that this favors a realistic interpretation of the quantum state. This paper proves that only observables that commute with the system's Hamiltonian can be measured protectively. It is argued that this restriction saves the coherence of alternative interpretations.
