量子手套

Quantum Gloves

D. Collins, L. Diosi, N. Gisin, S. Massar, S. Popescu

摘要:

“信息是有形的”这一口号如此成功,以至于导致了一些过剩。经典信息和量子信息可以独立于任何物理实现来考虑。纯信息任务可以使用这种抽象的c位和qu-bit来实现,但是物理任务需要c位或qu-bit的适当物理实现。作为例子,我们考虑的问题,沟通的手征。我们详细讨论了这所需要的物理资源,并引入了“量子手套”的自然概念,即旋转不变的量子态,尽可能多地编码手性的概念,仅此而已。

英文摘要:

The slogan "information is physical" has been so successful that it led to some excess. Classical and quantum information can be thought of independently of any physical implementation. Pure information tasks can be realized using such abstract c- and qu-bits, but physical tasks require appropriate physical realizations of c- or qu-bits. As illustration we consider the problem of communicating chirality. We discuss in detail the physical resources this necessitates, and introduce the natural concept of "quantum gloves", i.e. rotationally invariant quantum states that encode as much as possible the concept of chirality and nothing more.
