量子信息可以在没有物理实体的情况下以易失的形式存在

Quantum information can remain without physical body in volatile form

Brij Mohan, Sohail, Chirag Srivastava, Arun K. Pati, Ujjwal Sen

摘要:

经典和量子信息中一个根深蒂固的观点是“信息是物理的”,即,为了储存和处理信息,我们需要一个身体。在这里,我们要问的是,量子信息是否可以在没有物理实体的情况下继续存在。我们对这个问题的回答是肯定的,即,我们认为量子信息可以在没有物理实体的情况下以易失性的形式存在。我们引入了量子信息波动性的概念,并证明了在量子隐形传态协议中确实自然满足波动性的条件。我们认为,即使不假设狭义相对论原理,也有可能使量子信息不稳定。我们还讨论了古典极限的现象,以及多方的情况。

英文摘要:

A deeply rooted view in classical and quantum information is that "information is physical", i.e., to store and process information, we need a physical body. Here we ask whether quantum information can remain without a physical body. We answer this question in the affirmative, i.e., we argue that quantum information can exist without a physical body in volatile form. We introduce the notion of the volatility of quantum information and show that indeed the conditions for it are naturally satisfied in the quantum teleportation protocol. We argue that even if special relativity principles are not assumed, it is possible to make quantum information volatile. We also discuss the classical limit of the phenomenon, as well as the multiparty scenario.
