Deterministic entanglement generation between spatially separated electronic spins — •Mónica Benito¹, Martin Schütz², Gloria Platero¹, Geza Giedke^2,3, and Ignacio Cirac² — ¹Insituto de Ciencia de Materiales de Madrid, CSIC, 28049 Madrid, Spain — ²Max Planck Institut für Quantenoptik, Hans-Kopfermann Strasse I, D-85748, Garching, Germany — ³Donostia International Physics Center DIPC, Paseo Manuel de Lardizabal 4, 20018 Donostia-San Sebastián, Spain

We propose a scheme for deterministic entanglement generation between two electronic spin qubits confined in spatially separated quantum dots. The mechanism is based on electron transport through an ancilla system driving the system spins into an entangled target steady-state. Since the entangle- ment is actively stabilized by purely dissipative dynamics, our scheme is inherently robust against noise and imperfections.
