磁通量子比特态叠加假设与angular momentum守恒定律的矛盾
Contradiction between assumption on superposition of flux-qubit states and the law of angular momentum conservation
摘要:
被一个或三个约瑟夫森结中断的超导环在许多出版物中被认为是一种可能的量子比特,通量量子比特,可以用于创建量子计算机。但超导回路中两个宏观上不同的量子态叠加的假设与角动量守恒基本定律和普遍公认的量子形式主义相矛盾。许多致力于通量量子比特的出版物证明了许多作者对叠加原理和量子描述主题的矛盾性质的解释是不充分的。
英文摘要:
Superconducting loop interrupted by one or three Josephson junctions is considered in many publications as a possible quantum bit, flux qubit, which can be used for creation of quantum computer. But the assumption on superposition of two macroscopically distinct quantum states of superconducting loop contradict to the fundamental law of angular momentum conservation and the universally recognized quantum formalism. Numerous publications devoted to the flux qubit testify to an inadequate interpretation by many authors of paradoxical nature of superposition principle and the subject of quantum description.
