Experimental continuous-variable entanglement from a phase-difference-locked optical parametric oscillator
Jietai Jing, Sheng Feng, Russell Bloomer +1
We observed continuous-variable entanglement between the bright beams emitted above threshold by an ultrastable optical parametric oscillator, classically phase-locked at a frequen…
Sub-shot-noise heterodyne polarimetry
Sheng Feng, Olivier Pfister
We report the experimental demonstration of a heterodyne polarization rotation measurement with a noise floor 4.8 dB below the optical shot noise, by use of the classically phase-l…
Multipartite continuous-variable entanglement from concurrent nonlinearities
Olivier Pfister, Sheng Feng, Gregory Jennings +2
We show theoretically that concurrent interactions in a second-order nonlinear medium placed inside an optical resonator can generate multipartite entanglement between the resonato…
Quantum interference of ultrastable twin optical beams
Sheng Feng, Olivier Pfister
We report the first measurement of the quantum phase-difference noise of an ultrastable nondegenerate optical parametric oscillator that emits twin beams classically phase-locked a…
Stable nondegenerate optical parametric oscillation at degenerate frequencies in Na:KTP
Sheng Feng, Olivier Pfister
We report the realization of a light source specifically designed for the generation of bright continuous-variable entangled beams and for Heisenberg-limited inteferometry. The sou…
