We propose a quantum computing architecture based on the integration of nanomechanical
resonators with Josephson-junction phase qubits. The resonators are GHz-frequency …

As with classical information processing, a quantum information processor requires bits
(qubits) that can be independently addressed and read out, long-term memory elements to …

Quantum computers, if available, could perform certain tasks much more efficiently than
classical computers by exploiting different physical principles,,. A quantum computer would …

We discuss different ways of generating entanglement in the original picture of circuit QED
(XcQED) and several restrictions that arise in the context of a large-scale quantum …

We examine the possibility of coherent reversible information transfer between solid-state
superconducting qubits and ensembles of ultracold atoms. Strong coupling between these …

Hybrid quantum systems with inherently distinct degrees of freedom have a key role in many
physical phenomena. Well-known examples include cavity quantum electrodynamics …

The field of cavity quantum electrodynamics (QED), traditionally studied in atomic systems,,,
has gained new momentum by recent reports of quantum optical experiments with solid …
