According to quantum theory the energy exchange between physical systems is quantized.
As a direct consequence, measurement sensitivities are fundamentally limited by …

This Colloquium examines the field of the Einstein, Podolsky, and Rosen (EPR) gedanken
experiment, from the original paper of Einstein, Podolsky, and Rosen, through to modern …

Unique in that it is jointly written by an experimentalist and a theorist, this monograph
presents universal quantum computation based on quantum teleportation as an elementary …

We calculate the quantum correlations existing among the three output fields (pump, signal,
and idler) of a triply resonant nondegenerate optical parametric oscillator operating above …

Entangled states of light including low-loss optical fiber transmission and atomic resonance
frequencies are essential resources for future quantum information networks. We present the …

We theoretically and numerically study the quantum dynamics of two degenerate optical
parametric oscillators with mutual injections. The cavity mode in the optical coupling path …

We observed continuous-variable entanglement between the bright beams emitted above
threshold by an ultrastable optical parametric oscillator (OPO), classically phase locked at a …

Using a nondegenerate four-wave mixing process in hot rubidium vapor, we demonstrate a
compact diode-laser-pumped system for the generation of intensity-difference squeezing …

We experimentally demonstrated that the quantum correlations of amplitude and phase
quadratures between signal and idler beams produced from a non-degenerate optical …

This work discusses the single-intensity and difference-intensity detection schemes for lossy
Mach–Zehnder Interferometer (MZI) and gives the corresponding optimal conditions to …
