Shake before use: universal enhancement of quantum thermometry by unitary driving
Emanuele Tumbiolo, Lorenzo Maccone, Chiara Macchiavello +2
Quantum thermometry aims at determining temperature with ultimate precision in the quantum regime. Standard equilibrium approaches, limited by the Quantum Fisher Information given…
Experimental entropic uncertainty relations in dimensions three to five
Laura Serino, Giovanni Chesi, Benjamin Brecht +3
We provide experimental validation of tight entropic uncertainty relations for the Shannon entropies of observables with mutually unbiased eigenstates in high dimensions. In partic…
Quantum optical shallow networks
Simone Roncallo, Angela Rosy Morgillo, Seth Lloyd +2
Classical shallow networks are universal approximators. Given a sufficient number of neurons, they can reproduce any continuous function to arbitrary precision, with a resource cos…
Quantum stroboscopy for time measurements
Seth Lloyd, Lorenzo Maccone, Lionel Martellini +1
Mielnik's cannonball argument uses the Zeno effect to argue that projective measurements for time of arrival are impossible. If one repeatedly measures the position of a particle (…
Quantum Analog-to-Digital Converter for Phase Estimation
Eugenio Caruccio, Simone Roncallo, Valeria Cimini +9
Traditional quantum metrology assesses precision using the figures of merit of continuous-valued parameter estimation. Recently, quantum digital estimation was introduced: it evalu…
Quantum Measurements of Time: A reply to criticisms
Lorenzo Maccone, Simone Roncallo, Krzysztof Sacha
In [arXiv:2409.00161v1 (2024)] Cavendish et al. raise three criticisms against our time of arrival proposal [L. Maccone and K. Sacha, Phys. Rev. Lett. 124, 110402 (2020)]. Here we…
Quantum frequency resampling
Emanuele Tumbiolo, Simone Roncallo, Chiara Macchiavello +1
In signal processing, resampling algorithms can modify the number of resources encoding a collection of data points. Downsampling reduces the cost of storage and communication, whi…
