Four-qubit device with mixed couplings
M. Grajcar, A. Izmalkov, S. H. W. van der Ploeg +12
We present the first experimental results on a device with more than two superconducting qubits. The circuit consists of four three-junction flux qubits, with simultaneous ferro- a…
Low frequency Rabi spectroscopy for a dissipative two-level system
Ya. S. Greenberg, E. Il'ichev, A. Izmalkov
We have analyzed the interaction of a dissipative two level quantum system with high and low frequency excitation. The system is continuously and simultaneously irradiated by these…
Direct Josephson coupling between superconducting flux qubits
M. Grajcar, A. Izmalkov, S. H. W. van der Ploeg +8
We have demonstrated strong antiferromagnetic coupling between two three-junction flux qubits based on a shared Josephson junction, and therefore not limited by the small inductanc…
