Harvesting Multiqubit Entanglement from Ultrastrong Interactions in Circuit Quantum Electrodynamics
Federico Armata, Giuseppe Calajo, Tuomas Jaako +2
We analyze a multiqubit circuit QED system in the regime where the qubit-photon coupling dominates over the system's bare energy scales. Under such conditions a manifold of low-ene…
Intracity quantum communication via thermal microwave networks
Ze-Liang Xiang, Mengzhen Zhang, Liang Jiang +1
Communication over proven-secure quantum channels is potentially one of the most wide-ranging applications of currently developed quantum technologies. It is generally envisioned t…
Hybrid quantum device with nitrogen-vacancy centers in diamond coupled to carbon nanotubes
Peng-Bo Li, Ze-Liang Xiang, Peter Rabl +1
We show that nitrogen-vacancy (NV) centers in diamond interfaced with a suspended carbon nanotube carrying a dc current can facilitate a spin-nanomechanical hybrid device. We demon…
Non-classicality tests and entanglement witnesses for macroscopic mechanical superposition states
Oleg Gittsovich, Tobias Moroder, Ali Asadian +2
We describe a set of measurement protocols for performing non-classicality tests and the verification of entangled superposition states of macroscopic continuous variable systems,…
Two-dimensional Lattice Gauge Theories with Superconducting Quantum Circuits
D. Marcos, P. Widmer, E. Rico +4
A quantum simulator of U(1) lattice gauge theories can be implemented with superconducting circuits. This allows the investigation of confined and deconfined phases in quantum link…
Implementation of the Dicke lattice model in hybrid quantum system arrays
Liujun Zou, David Marcos, Sebastian Diehl +4
Generalized Dicke models can be implemented in hybrid quantum systems built from ensembles of nitrogen-vacancy (NV) centers in diamond coupled to superconducting microwave cavities…
