Feynman路径积分与互无偏基

Feynman's path integral and mutually unbiased bases

J Tolar, G Chadzitaskos

摘要:

本文应用我们以前在有限维希尔伯特空间中量子力学的工作,阐明了G.斯韦特利奇尼他推测,费曼路径积分的秘密可能在于时间邻近基的相互无偏性。我们通过将L^2(R)中量子力学的一个特别设计的N × N近似应用于我们的自由量子粒子的有限维模拟,来确认短时传播子的相应性质。

英文摘要:

Our previous work on quantum mechanics in Hilbert spaces of finite dimensions N is applied to elucidate the deep meaning of Feynman's path integral pointed out by G. Svetlichny. He speculated that the secret of the Feynman path integral may lie in the property of mutual unbiasedness of temporally proximal bases. We confirm the corresponding property of the short-time propagator by using a specially devised N x N -approximation of quantum mechanics in L^2(R) applied to our finite-dimensional analogue of a free quantum particle.
