Efficient generation of a maximally entangled state by repeated on-and off-resonant scattering of ancilla qubits
A scheme for preparing two fixed noninteracting qubits in a maximally entangled state is
presented. By repeating on-and off-resonant scattering of ancilla qubits, the target qubits are …

Influence of dissipation on the extraction of quantum states via repeated measurements
A quantum system put in interaction with another one that is repeatedly measured is subject
to a nonunitary dynamics, through which it is possible to extract subspaces. This key idea …
