Traditionally, the authors could establish secure computation protocols using variants of public key cryptology whose security is based on hard mathematics problems. However, classical protocols will become insecure owing to the emergence of quantum algorithms like Shors. In this paper, the authors demonstrate that nanoscale phenomenon can be applied not only in device level but also in high layer applications, such as secure computation. The authors study the possibility of performing secure computation by building non-local machines based on quantum entanglement and non-locality, which are phenomena available only at the nanometre scale. Comparing with classical secure computation algorithms, the security of this protocol is based on physical laws, instead of any unproven mathematic conjecture.
