Efficient Description of Parametric Amplification of Quantum Pulses
Victor Rueskov Christiansen, Klaus Mølmer, Emanuel Hubenschmid
A single quantum pulse undergoing parametric amplification feeds into at most two pulses in the output. In this work, we present an efficient, analytical method for finding the qua…
High fidelity photon-photon gates by scattering off a two-level quantum emitter
Love A. Pettersson, Victor R. Christiansen, Klaus Mølmer +1
We present a scheme for implementing a high-fidelity non-linear phase shift on a photonic state. The scheme is based on repeated scattering off a two-level quantum emitter embedded…
Phase-space open-systems dynamics of second-order nonlinear interactions with pulsed quantum light
Emanuel Hubenschmid, Victor Rueskov Christiansen
The theoretical description of broadband, multimode quantum pulses undergoing a second-order -nonlinear interaction can be quite intricate, due to the large dimensionality…
Interactions in Quantum Networks with Pulse Propagation Delays
Victor Rueskov Christiansen, Klaus Mølmer
The finite speed of light of pulses implies propagation delays between the generation of light, the interaction with different elements along its path and the final detection at th…
Subtraction and Addition of Propagating Photons by Two-Level Emitters
Mads M. Lund, Fan Yang, Victor Rueskov Christiansen +2
Coherent manipulation of quantum states of light is key to photonic quantum information processing. In this Letter, we show that a passive two-level nonlinearity suffices to implem…
Jaynes-Cummings interaction with a traveling light pulse
Victor Rueskov Christiansen, Mads Middelhede Lund, Fan Yang +1
The Jaynes-Cummings model provides a simple and accurate description of the interaction between a two-level quantum emitter and a single mode of quantum radiation. Due to the multi…
Parametric Amplification of a Quantum Pulse
Offek Tziperman, Victor Rueskov Christiansen, Ido Kaminer +1
Creating and manipulating quantum states of light requires nonlinear interactions, but while nonlinear optics is inherently multi-mode, quantum optical analyses are often done with…
Interaction of quantum systems with single pulses of quantized radiation
Victor Rueskov Christiansen, Alexander Holm Kiilerich, Klaus Mølmer
The interaction of a propagating pulse of quantum radiation with a localized quantum system can be described by a cascaded master equation with a distinct initially populated input…
