DOI: 10.1088/1751-8121/aaea13
Abstract: We consider two qubits interacting with a common bosonic bath, but not directly between themselves. We derive the (bipartite) entanglement generation conditions for Gaussian non-Markovian dynamical maps and show that they are similar as in… read more here.

DOI: 10.1103/physreva.98.012304
Abstract: We propose a protocol for state transfer and entanglement generation between two distant spin qubits (sender and receiver) that have different energies. The two qubits are permanently coupled to a far off-resonant spin-chain, and the… read more here.

DOI: 10.1103/physreva.98.052344
Abstract: An evolution between a system and its environment which leads to pure dephasing of the system may either be a result of entanglement building up between the system and the environment or not (the second… read more here.

DOI: 10.1103/physrevapplied.11.014017
Abstract: We investigate a non-adiabatic holonomic operation that enables us to entangle two fixed-frequency superconducting transmon qubits attached to a common bus resonator. Two coherent microwave tones are applied simultaneously to the two qubits and drive… read more here.

DOI: 10.7566/jpsj.90.104714
Abstract: Abstract The generation of quantum entanglement between phonons in photoirradiated remote electronphonon systems is numerically studied. Upon excitation by a visible/ultraviolet laser pulse, the entanglement of electrons is immediately generated and that of phonons follows… read more here.
