Generation of a superposition of odd photon number states for quantum information networks
J. S. Neergaard-Nielsen, B. Melholt Nielsen, C. Hettich +2
We report on the experimental observation of quantum-network-compatible light described by a non-positive Wigner function. The state is generated by photon subtraction from a squee…

An ultra-sensitive pulsed balanced homodyne detector: Application to time-domain quantum measurements
H. Hansen, T. Aichele, C. Hettich +4
A pulsed balanced homodyne detector has been developed for precise measurements of electric field quadratures of pulsed optical quantum states. A high level of common mode suppress…
