We study single-photon transport in an array of coupled microcavities where two two-level
atomic systems are embedded in two separate cavities of the array. We find that a single …

We show that a flying particle, such as an electron or a photon, scattering along a one-
dimensional waveguide from a pair of static spin-1 2 centers, such as quantum dots, can …

We investigate whether a two-qubit quantum gate can be implemented in a scattering
process involving a flying and a static qubit. To this end, we focus on a paradigmatic setup …

For a double quantum dot system in a parallel geometry, we demonstrate that by combining
the effects of a flux and driving an electrical current through the structure, the spin …

The use of spin torque as a substitute for magnetic fields is now well established for classical
operations like the switching of a nanomagnet. What we are describing here could be …

We present a scheme for the extraction of singlet states of two remote particles of arbitrary
quantum spin number. The goal is achieved through post-selection of the state of interaction …

We consider a double single-level quantum dot system with two embedded and nonaligned
spin impurities to manipulate the magnitude and polarization of the electron-spin density …

The study of geometric phase in quantum mechanics has so far been confined to discrete (or
continuous) spectra and trace-preserving evolutions. By considering only the transmission …

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 …

We present a protocol that sets maximum stationary entanglement between remote spins
through scattering of mobile mediators without initialization, post-selection or feedback of the …
