ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevX.3.031006||Abstract:||Device-independent quantum key distribution (DIQKD) in its current design requires a violation of a Bell's inequality between two parties, Alice and Bob, who are connected by a quantum channel. However, in reality, quantum channels are lossy and current DIQKD protocols are thus vulnerable to attacks exploiting the detection loophole of the Bell test. Here, we propose a novel approach to DIQKD that overcomes this limitation. In particular, we propose a protocol where the Bell test is performed entirely on two casually independent devices situated in Alice's laboratory. As a result, the detection loophole caused by the losses in the channel is avoided.||Source Title:||Physical Review X||URI:||https://scholarbank.nus.edu.sg/handle/10635/174650||ISSN:||2160-3308||DOI:||10.1103/PhysRevX.3.031006|
