Consistency of ground state and spectroscopic measurements on flux qubits
A. Izmalkov, S. H. W. van der Ploeg, S. N. Shevchenko +5
We compare the results of ground state and spectroscopic measurements carried out on superconducting flux qubits which are effective two-level quantum systems. For a single qubit a…
Resonant excitations of single and two-qubit systems coupled to a tank circuit
S. N. Shevchenko, S. H. W. van der Ploeg, M. Grajcar +3
The interaction of flux qubits with a low frequency tank circuit is studied. It is shown that changes in the state of the interacting qubits influence the effective impedance of th…
Sisyphus cooling and amplification by a superconducting qubit
M. Grajcar, S. H. W. van der Ploeg, A. Izmalkov +5
Laser cooling of the atomic motion paved the way for remarkable achievements in the fields of quantum optics and atomic physics, including Bose-Einstein condensation and the trappi…
Realization of a classical counterpart of a scalable design for adiabatic quantum computation
V. Zakosarenko, N. Bondarenko, S. H. W. van der Ploeg +6
We implement a classical counterpart of a scalable design for adiabatic quantum computation. The key element of this design is a coupler providing controllable coupling between two…
Controllable coupling of superconducting flux qubits
S. H. W. van der Ploeg, A. Izmalkov, Alec Maassen van den Brink +5
We have realized controllable coupling between two three-junction flux qubits by inserting an additional coupler loop between them, containing three Josephson junctions. Two of the…
Measurement of the ground-state flux diagram of three coupled qubits as a first step towards the demonstration of adiabatic quantum computation
A. Izmalkov, M. Grajcar, S. H. W. van der Ploeg +4
The ground state susceptibility of a system consisting of three flux-qubits was measured in the complete three dimensional flux space around the common degeneracy point of the qubi…
