Implementation of two-party protocols in the noisy-storage model
Stephanie Wehner, Marcos Curty, Christian Schaffner +1
The noisy-storage model allows the implementation of secure two-party protocols under the sole assumption that no large-scale reliable quantum storage is available to the cheating…
Bounds on probability of transformations between multi-partite pure states
Wei Cui, Wolfram Helwig, Hoi-Kwong Lo
For a tripartite pure state of three qubits, it is well known that there are two inequivalent classes of genuine tripartite entanglement, namely the GHZ-class and the W-class. Any…
Experimental demonstration of a high speed quantum random number generation scheme based on measuring phase noise of a single mode laser
Bing Qi, Yue-Meng Chi, Hoi-Kwong Lo +1
We present a high speed random number generation scheme based on measuring the quantum phase noise of a single mode diode laser operating at a low intensity level near the lasing t…
Security Analysis of an Untrusted Source for Quantum Key Distribution: Passive Approach
Yi Zhao, Bing Qi, Hoi-Kwong Lo +1
We present a passive approach to the security analysis of quantum key distribution (QKD) with an untrusted source. A complete proof of its unconditional security is also presented.…
Upper bounds for the secure key rate of decoy state quantum key distribution
Marcos Curty, Tobias Moroder, Xiongfeng Ma +2
The use of decoy states in quantum key distribution (QKD) has provided a method for substantially increasing the secret key rate and distance that can be covered by QKD protocols w…
