Quantum control of an oscillator using stimulated nonlinearity
Andrei Vrajitoarea, Ziwen Huang, Peter Groszkowski +2
Superconducting circuits extensively rely on the Josephson junction as a nonlinear electronic element for manipulating quantum information and mediating photon interactions. Despit…
Suppression of Qubit Crosstalk in a Tunable Coupling Superconducting Circuit
Pranav S. Mundada, Gengyan Zhang, Thomas Hazard +1
Parasitic crosstalk in superconducting quantum devices is a leading limitation for quantum gates. We demonstrate the suppression of static ZZ crosstalk in a two-qubit, two-coupler…
Nanowire Superinductance Fluxonium Qubit
T. M. Hazard, András Gyenis, A. Di Paolo +4
We characterize a fluxonium qubit consisting of a Josephson junction inductively shunted with a NbTiN nanowire superinductance. We explain the measured energy spectrum by means of…
Hyperbolic Lattices in Circuit Quantum Electrodynamics
Alicia J. Kollár, Mattias Fitzpatrick, Andrew A. Houck
After close to two decades of research and development, superconducting circuits have emerged as a rich platform for both quantum computation and quantum simulation. Lattices of su…
Interacting Qubit-Photon Bound States with Superconducting Circuits
Neereja M. Sundaresan, Rex Lundgren, Guanyu Zhu +2
Qubits strongly coupled to a photonic crystal give rise to many exotic physical scenarios, beginning with single and multi-excitation qubit-photon dressed bound states comprising i…
