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…
