2016/1/23
We report a free-space entanglement-based quantum key dis-tribution experiment, implementing the biased basis protocol between two sites which are 15.3 km apart. Photon pairs from a polarization-entan...

Measurement-device-independent quantum key distribution (MDIQKD) protocol is immune to all attacks on detection and guarantees the information-theoretical security even with imperfect single-photon de...
Min-entropy and quantum key distribution: non-zero key rates for "small" numbers of signals
min-entropy quantum key distribution non-zero key rates
2010/11/8
We calculate an achievable secret key rate for quantum key distribution with a finite number of signals, by evaluating the min-entropy explicitly. The min-entropy can be expressed in terms of the gues...

2010/11/8
We address continuous variable quantum key distribution (QKD) in non-Markovian lossy channels and show how the non-Markovian features may be exploited to enhance security and/or to detect the presence...

Device-Independent Quantum Key Distribution ommuting Measurements
2010/10/19
We consider quantum key distribution in the device-independent scenario, i.e., where the
legitimate parties do not know (or trust) the exact specification of their apparatus. We show
how secure key ...

2010/10/18
In practical quantum key distribution (QKD) system, the state prepara-tion and measurement are imperfect comparing with the ideal BB84 proto-col, which are always state-dependent in practical realizat...
