Quantum-Optimal Frequency Estimation of Stochastic AC Fields
Anirban Dey, Sara Mouradian, Cosmo Lupo +1
Resolving frequencies in a time-dependent field is classically limited by the measurement bandwidth. Using tools from quantum metrology and quantum control may overcome this limit,…
Quantum hypothesis testing for exoplanet detection
Zixin Huang, Cosmo Lupo
Detecting the faint emission of a secondary source in the proximity of the much brighter source has been the most severe obstacle for using direct imaging in searching for exoplane…
Experimental implementation of secure anonymous protocols on an eight-user quantum network
Zixin Huang, Siddarth Koduru Joshi, Djeylan Aktas +12
Anonymity in networked communication is vital for many privacy-preserving tasks. Secure key distribution alone is insufficient for high-security communications, often knowing who t…
Quantum-limited estimation of range and velocity
Zixin Huang, Cosmo Lupo, Pieter Kok
The energy-time uncertainty relation puts a fundamental limit on the precision of radars and lidars for the estimation of range and velocity. The precision in the estimation of the…
Ancilla-assisted schemes are beneficial for Gaussian state phase estimation
Zixin Huang, Chiara Macchiavello, Lorenzo Maccone +1
We study interferometry with Gaussian states and show that an ancilla-assisted scheme outperforms coherent state interferometry for all levels of loss. We also compare the ancilla-…
Noise-dependent optimal strategies for quantum metrology
Zixin Huang, Chiara Macchiavello, Lorenzo Maccone
We show that for some noisy channels, the optimal entanglement-assisted strategy depends on the noise level. We note that there is a non-trivial crossover between the parallel-enta…
