Quantum-limited imaging using diffractive optical neural networks
Aakash Warke, Aonan Zhang, A. I. Lvovsky
We cast general imaging as multiparameter quantum estimation of band-limited spatial-frequency amplitudes. For separable (single-copy) measurements, we compute precision limits usi…
Passive Imaging with Quantum Advantage
Li Gong, Aonan Zhang, Madhura Ghosh Dastidar +2
Far-field optical imaging inevitably involves low-pass spatial filtering, limiting the resolution. Moreover, conventional imaging suppresses high spatial frequency components close…
Time Crystals as Passively Protected Oscillating Qubits
Mert Esencan, A. I. Lvovsky, Berislav Buča
Protecting information against decoherence in open quantum systems remains a central challenge for quantum computing. In particular, passive error correction schemes have so far be…
Linear-optical processing cannot increase photon efficiency
D. W. Berry, A. I. Lvovsky
We answer the question whether linear-optical processing of the states produced by one or multiple imperfect single-photon sources can improve the single-photon fidelity. This proc…
Remote preparation of a single-mode photonic qubit by measuring field quadrature noise
S. A. Babichev, B. Brezger, A. I. Lvovsky
An electromagnetic field quadrature measurement, performed on one of the modes of the nonlocal single-photon state , collapses it into a superposition of the single-…
Nonclassical character of statistical mixtures of the single-photon and vacuum optical states
A. I. Lvovsky, J. H. Shapiro
We demonstrate, theoretically and experimentally, that statistical mixtures of the vacuum state |0> and the single-photon Fock state |1> are nonclassical according to the Vogel cri…
