Losses in coplanar waveguide resonators at millikelvin temperatures
P. Macha, S. H. W. van der Ploeg, G. Oelsner +4
We study the loss rate for a set of lambda/2 coplanar waveguide resonators at millikelvin temperatures (20 mK - 900mK) and different applied powers (3E-19 W - 1E-12 W). The loss ra…
Weak continuous monitoring of a flux qubit using coplanar waveguide resonator
G. Oelsner, S. H. W. van der Ploeg, P. Macha +9
We study a flux qubit in a coplanar waveguide resonator by measuring transmission through the system. In our system with the flux qubit decoupled galvanically from the resonator, t…
Multiphoton excitations and inverse population in two-flux-qubit system
E. Il'ichev, S. N. Shevchenko, S. H. W. van der Ploeg +4
We study spectroscopy of artificial solid-state four-level quantum system. This system is formed by two coupled superconducting flux qubits. When multiple driving frequency of the…
Adiabatic quantum computation with flux qubits, first experimental results
S. H. W. van der Ploeg, A. Izmalkov, M. Grajcar +10
Controllable adiabatic evolution of a multi-qubit system can be used for adiabatic quantum computation (AQC). This evolution ends at a configuration where the Hamiltonian of the sy…
