Pilot-assisted intradyne reception for high-speed continuous-variable quantum key distribution with true local oscillator
Fabian Laudenbach, Bernhard Schrenk, Christoph Pacher +6
We present a pilot-assisted coherent intradyne reception methodology for CV-QKD with true local oscillator. An optically phase-locked reference tone, prepared using carrier-suppres…
Continuous-Variable Quantum Key Distribution with Gaussian Modulation -- The Theory of Practical Implementations
Fabian Laudenbach, Christoph Pacher, Chi-Hang Fred Fung +6
Quantum key distribution using weak coherent states and homodyne detection is a promising candidate for practical quantum-cryptographic implementations due to its compatibility wit…
Tight bounds of quantum speed limit for noisy dynamics via maximum rotation angles
Zihao Hu, Haidong Yuan, Zigui Zhang +2
The laws of quantum physics place a limit on the speed of computation. In particular, the evolution time of a system from an initial state to a final state cannot be arbitrarily sh…
Quantum parameter estimation with general dynamics
Haidong Yuan, Chi-Hang Fred Fung
One of the main quests in quantum metrology, and quantum parameter estimation in general, is to find out the highest achievable precision with given resources and design schemes th…
Fidelity and Fisher information on quantum channels
Haidong Yuan, Chi-Hang Fred Fung
The fidelity function of quantum states have been widely used in quantum information science and frequently arises in the quantification of optimal performances for the estimation…
Universal time scaling for Hamiltonian parameter estimation
Haidong Yuan, Chi-Hang Fred Fung
Time is a valuable resource and it seems intuitive that longer time should lead to better precision in Hamiltonian parameter estimation. However recent studies have put this intuit…
