Device-independent quantum key distribution
Quantum key distribution allows two parties connected by a quantum channel to establish a secret key that is unknown to any unauthorized third party. The secrecy of this key is based on the laws of quantum physics. For security, however, it is crucial that the honest parties are able to control their physical devices accurately and completely. The goal of device-independent quantum key distribu...

متن کاملThree particle Hyper Entanglement: Teleportation and Quantum Key Distribution
Entanglement acts as an important resource for quantum information and communication. With entanglement between two quantum bits, protocols have been demonstrated for teleporting an unknown qubit [1], denser coding of information [2] and secure communication [3]. An arbitrary qubit can be teleported from one particle to another, irrespective of the distance, with the use of an entangled pair of...
متن کاملExperimental measurement-device-independent quantum key distribution.
Quantum key distribution is proven to offer unconditional security in communication between two remote users with ideal source and detection. Unfortunately, ideal devices never exist in practice and device imperfections have become the targets of various attacks. By developing up-conversion single-photon detectors with high efficiency and low noise, we faithfully demonstrate the measurement-dev...
متن کاملOptimal Device Independent Quantum Key Distribution
We consider an optimal quantum key distribution setup based on minimal number of measurement bases with binary yields used by parties against an eavesdropper limited only by the no-signaling principle. We note that in general, the maximal key rate can be achieved by determining the optimal tradeoff between measurements that attain the maximal Bell violation and those that maximise the bit corre...
