Frequency fluctuations of ferromagnetic resonances at milliKelvin temperatures
Tim Wolz, Luke McLellan, Alexander Stehli +5
Unwanted fluctuations over time, in short, noise, are detrimental to device performance, especially for quantum coherent circuits. Recent efforts have demonstrated routes to utiliz…
Topological photon pairs in a superconducting quantum metamaterial
Ilya S. Besedin, Maxim A. Gorlach, Nikolay N. Abramov +9
Recent discoveries in topological physics hold a promise for disorder-robust quantum systems and technologies. Topological states provide the crucial ingredient of such systems fea…
Introducing coherent time control to cavity-magnon-polariton modes
Tim Wolz, Alexander Stehli, Andre Schneider +5
By connecting light to magnetism, cavity-magnon-polaritons (CMPs) can build links from quantum computation to spintronics. As a consequence, CMP-based information processing device…
Resonance inversion in a superconducting cavity coupled to artificial atoms and a microwave background
Juha Leppäkangas, Jan David Brehm, Ping Yang +4
We demonstrate how heating of an environment can invert the line shape of a driven cavity. We consider a superconducting coplanar cavity coupled to multiple artificial atoms. The m…
Fluxon-Based Quantum Simulation in Circuit QED
Alexandru Petrescu, Hakan E. Türeci, Alexey V. Ustinov +1
Long-lived fluxon excitations can be trapped inside a superinductor ring, which is divided into an array of loops by a periodic sequence of Josephson junctions in the quantum regim…
Electrically and Magnetically Resonant dc SQUID Metamaterials
O. V. Shramkova, N. Lazarides, G. P. Tsironis +1
We propose a superconducting metamaterial design consisting of meta-atoms (MAs) which are each composed of a direct current (dc) superconducting quantum interference device (SQUID)…
