Divide et impera: hybrid multinomial classifiers from quantum binary models

Simone Roncallo, Angela Rosy Morgillo, Seth Lloyd +2

We investigate how to combine a collection of quantum binary models into a multinomial classifier. We employ a hybrid approach, adopting strategies like one-vs-one, one-vs-rest and…

Quantum Optical Neuron for Image Classification via Multiphoton Interference

Giorgio Minati, Simone Roncallo, Simone Scrofana +6

The rapid growth of machine learning is increasingly constrained by the energy and bandwidth limits of classical hardware. Optical and quantum technologies offer an alternative rou…

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 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…
