Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

Research in quantum information processing has followed two different directions: the use of
discrete variables (qubits) and that of high-dimensional, continuous-variable Gaussian …

Memristive devices are a class of physical systems with history-dependent dynamics
characterized by signature hysteresis loops in their input–output relations. In the past few …

Conventional spectroscopy uses classical light to detect matter properties through the
variation of its response with frequencies or time delays. Quantum light opens up new …

We explore photon coincidence counting statistics in the ultrastrong coupling regime, where
the atom-cavity coupling rate becomes comparable to the cavity resonance frequency. In this …

We show how techniques from machine learning and optimization can be used to find
circuits of photonic quantum computers that perform a desired transformation between input …

Superpositions of macroscopically distinct quantum states, introduced in Schrödinger's
famous Gedankenexperiment, are an epitome of quantum 'strangeness' and a natural tool …

The basic idea of squeezing can be understood by considering the quantum harmonic
oscillator, familiar from undergraduate quantum mechanics. Squeezing is best visualized by …

We implement an ultrafast pulsed type-II parametric down conversion source in a
periodically poled KTP waveguide at telecommunication wavelengths with almost identical …

We theoretically investigate the performance of multiphoton catalysis applied on the two-
mode squeezed state by examining the entropy of entanglement, logarithmic negativity …
