Improved success probability with greater circuit depth for the quantum approximate optimization algorithm
Andreas Bengtsson, Pontus Vikstål, Christopher Warren +12
Present-day, noisy, small or intermediate-scale quantum processors---although far from fault-tolerant---support the execution of heuristic quantum algorithms, which might enable a…
Period multiplication in a parametrically driven superconducting resonator
Ida-Maria Svensson, Andreas Bengtsson, Jonas Bylander +2
We report on the experimental observation of period multiplication in parametrically driven tunable superconducting resonators. We modulate the magnetic flux through a superconduct…
Resonant and off-resonant microwave signal manipulation in coupled superconducting resonators
Mathieu Pierre, Sankar Raman Sathyamoorthy, Ida-Maria Svensson +2
We present an experimental demonstration as well as a theoretical model of an integrated circuit designed for the manipulation of a microwave field down to the single-photon level.…
Observation of broadband entanglement in microwave radiation from a single time-varying boundary condition
B. H. Schneider, A. Bengtsson, I. M. Svensson +4
Entangled pairs of microwave photons are commonly produced in the narrow frequency band of a resonator, which represents a modified vacuum density of states. We use a broadband, se…
Period-tripling subharmonic oscillations in a driven superconducting resonator
Ida-Maria Svensson, Andreas Bengtsson, Philip Krantz +3
We have observed period-tripling subharmonic oscillations, in a superconducting coplanar waveguide resonator operated in the quantum regime, . The resonator is te…
