Nonexponential decay of a giant artificial atom
Gustav Andersson, Baladitya Suri, Lingzhen Guo +2
In quantum optics, light-matter interaction has conventionally been studied using small atoms interacting with electromagnetic fields with wavelength several orders of magnitude la…
Probing the Tavis-Cummings level splitting with intermediate-scale superconducting circuits
Ping Yang, Jan David Brehm, Juha Leppäkangas +7
We demonstrate the local control of up to eight two-level systems interacting strongly with a microwave cavity. Following calibration, the frequency of each individual two-level sy…
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…
Scalable Ion Trap Architecture for Universal Quantum Computation by Collisions
Pengfei Liang, Lingzhen Guo
We propose a scalable ion trap architecture for universal quantum computation, which is composed of an array of ion traps with one ion confined in each trap. The neighboring traps…
Local Sensing with the Multi-Level AC Stark Effect
Andre Schneider, Jochen Braumüller, Lingzhen Guo +5
Analyzing weak microwave signals in the GHz regime is a challenging task if the signal level is very low and the photon energy widely undefined. A superconducting qubit can detect…
