-{{:​news:​banner_prx.png?​nolink&​400 }} In our first [[publications:​bib:​lim2013a| paper]] published in the all new [[http://​prx.aps.org/​| Physical Review X]] journal, we propose a novel approach to device-independent quantum key distribution (DIQKD). This family of protocols enables the generation of a secret key via the violation of a Bell inequality, but crucially does not require precise models for the devices used in the protocol. This fact makes DIQKD the ultimate solution in terms of security against device flaws and side-channel attacks. A drawback in existing DIQKD protocols is requirement of a two party Bell test, which opens up the detection loophole as soon as a realistic distance (channel loss) is introduced between the two users. In this work, we propose a way of circumventing this with a Bell test carried out by only one party, enabling DIQKD over longer distances.+{{:​news:​banner_prx.png?​nolink&​400 }} In our first [[publications:​bib:​lim2013a| paper]] published in the all new [[http://​prx.aps.org/​| Physical Review X]] journal, we propose a novel approach to device-independent quantum key distribution (DIQKD).
