The entangling power of non-entangling channels
Julien Pinske, Jan Sperling, Klaus Mølmer
There are processes that cannot generate entanglement but may, nevertheless, amplify entanglement already present in a system. Here, we show that a non-entangling operation can inc…
Censorship of quantum resources against catalytic account sharing
Julien Pinske, Klaus Mølmer
In quantum censorship, an agency oversees quantum communication in a public-domain network. The agency restricts the users communication to the free states of a quantum resource th…
Supercoherence: Harnessing Long-Range Interactions to Preserve Collective Coherence in Disordered Systems
Alexey Gorlach, Andrea Pizzi, Klaus Mølmer +3
Artificial quantum systems with synthetic dimensions enable exploring novel quantum phenomena difficult to create in conventional materials. These synthetic degrees of freedom incr…
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…
Stochastic Schrödinger equation for a homodyne measurement setup of strongly correlated systems
Aniket Patra, Felix Motzoi, Klaus Mølmer
Starting from an experimentally feasible atomic setup, we derive a stochastic Schrödinger equation that captures the homodyne detection record of a strongly interacting system. App…
