Quantum theory of optical temporal phase and instantaneous frequency. II. Continuous time limit and state-variable approach to phase-locked loop design
Mankei Tsang, Jeffrey H. Shapiro, Seth Lloyd
We consider the continuous-time version of our recently proposed quantum theory of optical temporal phase and instantaneous frequency [Tsang, Shapiro, and Lloyd, Phys. Rev. A 78, 0…
Correlation Matrices of Two-Mode Bosonic Systems
Stefano Pirandola, Alessio Serafini, Seth Lloyd
We present a detailed analysis of all the algebraic conditions an arbitrary 4x4 symmetric matrix must satisfy in order to represent the correlation matrix of a two-mode bosonic sys…
Experimental Quantum Private Queries with linear optics
F. De Martini, V. Giovannetti, S. Lloyd +4
The Quantum Private Query is a quantum cryptographic protocol to recover information from a database, preserving both user and data privacy: the user can test whether someone has r…
Eavesdropping of two-way coherent-state quantum cryptography via Gaussian quantum cloning machines
Stefano Pirandola, Stefano Mancini, Seth Lloyd +1
We consider one of the quantum key distribution protocols recently introduced in Ref. [Pirandola et al., Nature Physics 4, 726 (2008)]. This protocol consists in a two-way quantum…
