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…

Retrodiction of measurement outcomes on a single quantum system reveals entanglement with its environment
Julien Pinske, Klaus Mølmer
The density matrix yields probabilistic information about the outcome of measurements on a quantum system, but it does not distinguish between classical randomness in the preparati…
