Phase randomization improves the security of quantum key distribution
Hoi-Kwong Lo, John Preskill
Ideal quantum key distribution (QKD) protocols call for a source that emits single photon signals, but the sources used in typical practical realizations emit weak coherent states…
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…
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…
Robustness of adiabatic quantum computation
Andrew M. Childs, Edward Farhi, John Preskill
We study the fault tolerance of quantum computation by adiabatic evolution, a quantum algorithm for solving various combinatorial search problems. We describe an inherent robustnes…
Quantum clock synchronization and quantum error correction
John Preskill
I consider quantum protocols for clock synchronization, and investigate in particular whether entanglement distillation or quantum error-correcting codes can improve the robustness…
Fault-tolerant quantum computation
John Preskill
The discovery of quantum error correction has greatly improved the long-term prospects for quantum computing technology. Encoded quantum information can be protected from errors th…
