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…
Secure quantum key distribution using squeezed states
Daniel Gottesman, John Preskill
We prove the security of a quantum key distribution scheme based on transmission of squeezed quantum states of a harmonic oscillator. Our proof employs quantum error-correcting cod…
Encoding a qubit in an oscillator
Daniel Gottesman, Alexei Kitaev, John Preskill
Quantum error-correcting codes are constructed that embed a finite-dimensional code space in the infinite-dimensional Hilbert space of a system described by continuous quantum vari…
Simple Proof of Security of the BB84 Quantum Key Distribution Protocol
Peter W. Shor, John Preskill
We prove the security of the 1984 protocol of Bennett and Brassard (BB84) for quantum key distribution. We first give a key distribution protocol based on entanglement purification…
