Entanglement generation via a completely mixed nuclear spin bath

H. Christ, J. I. Cirac, G. Giedke

We show that qubits coupled sequentially to a mesoscopic static completely mixed spin bath via the Heisenberg interaction can become highly entangled. Straightforward protocols for…

Orthogonally-Driven Superconducting Qubit in Circuit QED

M. J. Storcz, M. Mariantoni, H. Christ +6

We consider a superconducting charge qubit coupled to distinct orthogonal electromagnetic field modes belonging to a coplanar wave guide and a microstrip transmission line resonato…

Quantum Description of Nuclear Spin Cooling in a Quantum Dot

H. Christ, J. I. Cirac, G. Giedke

We study theoretically the cooling of an ensemble of nuclear spins coupled to the spin of a localized electron in a quantum dot. We obtain a master equation for the state of the nu…

Effective Quantum Dynamics of Interacting Systems with Inhomogeneous Coupling

C. E. Lopez, H. Christ, J. C. Retamal +1

We study the quantum dynamics of a single mode/particle interacting inhomogeneously with a large number of particles and introduce an effective approach to find the accessible Hilb…

On-Chip Microwave Fock States and Quantum Homodyne Measurements

M. Mariantoni, M. J. Storcz, F. K. Wilhelm +6

We propose a method to couple metastable flux-based qubits to superconductive resonators based on a quantum-optical Raman excitation scheme that allows for the deterministic genera…

Quantum information processing using localized ensembles of nuclear spins

J. M. Taylor, G. Giedke, H. Christ +5

We describe a technique for quantum information processing based on localized en sembles of nuclear spins. A qubit is identified as the presence or absence of a collective excitati…
