Deterministic quantum teleportation between distant atomic objects
H. Krauter, D. Salart, C. A. Muschik +4
Quantum teleportation is a key ingredient of quantum networks and a building block for quantum computation. Teleportation between distant material objects using light as the quantu…
Performance bound for quantum absorption refrigerators
Luis A. Correa, José P. Palao, Gerardo Adesso +1
An implementation of quantum absorption chillers with three qubits has been recently proposed, that is ideally able to reach the Carnot performance regime. Here we study the workin…
Measuring bipartite quantum correlations of an unknown state
I. A. Silva, D. Girolami, R. Auccaise +6
We report the experimental measurement of bipartite quantum correlations of an unknown two-qubit state. Using a liquid state Nuclear Magnetic Resonance (NMR) setup and employing ge…
Characterizing Nonclassical Correlations via Local Quantum Uncertainty
Davide Girolami, Tommaso Tufarelli, Gerardo Adesso
Quantum mechanics predicts that measurements of incompatible observables carry a minimum uncertainty which is independent of technical deficiencies of the measurement apparatus or…
Time evolution techniques for detectors in relativistic quantum information
David Edward Bruschi, Antony R. Lee, Ivette Fuentes
The techniques employed to solve the interaction of a detector and a quantum field typically require perturbation methods. We introduce mathematical techniques to solve the time ev…
Fermionic mode entanglement in quantum information
Nicolai Friis, Antony R. Lee, David Edward Bruschi
We analyze fermionic modes as fundamental entities for quantum information processing. To this end we construct a density operator formalism on the underlying Fock space and demons…
