A superconducting chip containing a regular array of flux qubits, tunable interqubit inductive
couplers, an XY-addressable readout system, on-chip programmable magnetic memory …

Superconducting qubits, behave as artificial two-level atoms and are used to investigate
fundamental quantum phenomena. In this context, the study of multiphoton excitations …

We introduce a systematic formalism for two-resonator circuit QED, where two on-chip
microwave resonators are simultaneously coupled to one superconducting qubit. Within this …

We analyze the performance of a microwave chip mount that uses wirebonds to connect the
chip and mount grounds. A simple impedance ladder model predicts that transmission …

For gradiometric three-Josephson-junction flux qubits, we perform a systematic study on the
tuning of the minimal transition frequency, the so-called qubit gap. By replacing one of the …

Within the lowest-order Born approximation, we calculate the exact dynamics of a qubit in
the presence of 1/f noise without Markov approximation. We show that the non-Markovian …

Dispersive coupling based on the Rabi model with large detuning is widely used for qubit
quantum nondemolition (QND) readout in quantum computation. However, the …

Iron plays important physiological and pathological roles in the human body. However,
microscopic analysis including redox status by a conventional electron spin resonance …

Ground state cooling of a nanomechanical resonator coupled to a superconducting flux
qubit is discussed. By inducing quantum interference to cancel unwanted heating …

We present a theoretical treatment for the dissipative two-resonator circuit quantum
electrodynamics setup referred to as quantum switch. There, switchable coupling between …
