It was suggested in (Motes et al 2015 Phys. Rev. Lett. 114 170802) that optical networks with
relatively inexpensive overheads—single photon Fock states, passive optical elements, and …

Quantum number-path entanglement is a resource for supersensitive quantum metrology
and in particular provides for sub-shot-noise or even Heisenberg-limited sensitivity …

We present a framework for studying bosonic non-Gaussian channels of continuous-
variable systems. Our emphasis is on a class of channels that we call photon-added …

Multi-mode NOON states have been attracting increasing attentions recently for their abilities
of obtaining supersensitive and superresolved measurements for simultaneous multiple …

Phase estimation is used in many quantum algorithms, particularly in order to estimate
energy eigenvalues for quantum systems. When using a single qubit as the probe (used to …

Optical absorption measurements characterize a wide variety of systems from atomic gases
to in vivo diagnostics of living organisms. Here we study the potential of nonclassical …

High-quality single-photon sources are crucial for the development of simple quantum
devices. Quantum communication stands at the forefront of cutting-edge technologies …

Single-and two-mode multiphoton states are the cornerstone of many quantum
