Quantum Information Processing with Adversarial Devices [article]

Matthew McKague
2010 arXiv   pre-print
We consider several applications in black-box quantum computation in which untrusted physical quantum devices are connected together to produce an experiment.  ...  This is useful in order to verify that a calculation has been performed correctly, that measurement outcomes are secure, or that the devices are producing the desired state.  ...  The devices are considered to be adversarial, always operating in such a way as to maximize the information leakage to Eve.  ...

Security of practical private randomness generation

to show that the generated string is random with respect to an adversary that holds only classical-side information, i.e., proving randomness against quantum-side information is not necessary.  ...  Since this process requires a small initial random seed, one usually speaks of device-independent randomness expansion. The purpose of this paper is twofold.  ...  This quantum information can be intercepted by the adversary and entangled with his own quantum system.  ...

Security of Trusted Repeater Quantum Key Distribution Networks [article]

Louis Salvail, Momtchil Peev, Eleni Diamanti, Romain Alleaume, Norbert Lutkenhaus, Thomas Laenger
2009 arXiv   pre-print
A Quantum Key Distribution (QKD) network is an infrastructure capable of performing long-distance and high-rate secret key agreement with information-theoretic security.  ...  We conclude that secret keys can be generated through disjoint paths in a private and authentic way against ( − 1)-bounded adversaries and against ( − 2)bounded adversaries with honest-but-curious paths  ...  We suppose that Alice and Bob do not share key material to start with. They only share keys with their direct neighbours.  ...

Location-dependent communications using quantum entanglement

Robert A. Malaney
2010 Physical Review A. Atomic, Molecular, and Optical Physics  
In this work we show how unconditional location verification can be achieved with the use of quantum communication channels.  ...  Quantum location verification represents a new application of quantum entanglement that delivers a feat not possible in the classical-only channel.  ...  This being the case, an adversary with no device at the location being verified cannot pass the verification test.  ...

Weak randomness seriously limits the security of quantum key distribution

Jan Bouda, Matej Pivoluska, Martin Plesch, Colin Wilmott
2012 Physical Review A. Atomic, Molecular, and Optical Physics  
In usual security proofs of quantum protocols the adversary (Eve) is expected to have full control over any quantum communication between any communicating parties (Alice and Bob).  ...  Unconditional security against any attack by Eve can be proved even in the realistic setting of device and channel imperfection.  ...  Recent investigations have shown that quantum-information processing can help to increase security of communication using weak randomness even for regions of parameters where purely classical processing  ...
