Stimulated Emission Tomography: Beyond Polarization
Mario Arnolfo Ciampini, Andrea Geraldi, Valeria Cimini +4
In this work we demonstrate the use of stimulated emission tomography to characterize a hyper-entangled state generated by spontaneous parametric down-conversion in a CW-pumped sou…
An Artificial Neuron Implemented on an Actual Quantum Processor
Francesco Tacchino, Chiara Macchiavello, Dario Gerace +1
Artificial neural networks are the heart of machine learning algorithms and artificial intelligence protocols. Historically, the simplest implementation of an artificial neuron tra…
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…
