An Ultrafast Quantum Pulse Gate — •Benjamin Brecht, Andreas Eckstein, Andreas Christ, and Christine Silberhorn — Integrated Quantum Optics, Applied Physics, University of Paderborn, 33098 Paderborn, Germany

Ultrafast photonics quantum states feature a rich inherent structure, since they generally consist of a multitude of temporal, orthogonal pulses. Thus, they allow for novel, powerful information coding schemes, where those pulses play the role of information carrier. In earlier work, we have proposed a Quantum Pulse Gate (QPG) to single out and manipulate single pulses from such a manifold in a highly controlled and flexible way [1,2]. This is made possible by precise engineering of the gating process and by shaping the classical, bright pulses used to drive the process. Here, we give an update on the experimental progress of this work.
