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…
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…
Reading-out the state inductively and microwave spectroscopy of an interferometer-type charge qubit
D. Born, V. I. Shnyrkov, W. Krech +5
We implemented experimentally an interferometer-type charge qubit consisting of a single-Cooper-pair transistor closed by a superconducting loop that is in flip-chip configuration…
