Classicality in discrete Wigner functions
Cecilia Cormick, Ernesto F. Galvao, Daniel Gottesman +2
Gibbons et al. [Phys. Rev. A 70, 062101(2004)] have recently defined a class of discrete Wigner functions W to represent quantum states in a Hilbert space with finite dimension. We…
Quantum accuracy threshold for concatenated distance-3 codes
Panos Aliferis, Daniel Gottesman, John Preskill
We prove a new version of the quantum threshold theorem that applies to concatenation of a quantum code that corrects only one error, and we use this theorem to derive a rigorous l…
Approximate Quantum Error-Correcting Codes and Secret Sharing Schemes
Claude Crepeau, Daniel Gottesman, Adam Smith
It is a standard result in the theory of quantum error-correcting codes that no code of length n can fix more than n/4 arbitrary errors, regardless of the dimension of the coding a…
Security of quantum key distribution with imperfect devices
Daniel Gottesman, Hoi-Kwong Lo, Norbert Lütkenhaus +1
We prove the security of the Bennett-Brassard (BB84) quantum key distribution protocol in the case where the source and detector are under the limited control of an adversary. Our…
Uncloneable Encryption
Daniel Gottesman
Quantum states cannot be cloned. I show how to extend this property to classical messages encoded using quantum states, a task I call "uncloneable encryption." An uncloneable encry…
Secure Multi-party Quantum Computing
Claude Crepeau, Daniel Gottesman, Adam Smith
Secure multi-party computing, also called "secure function evaluation", has been extensively studied in classical cryptography. We consider the extension of this task to computatio…
