Quantum behaviour of a flux qubit coupled to a resonator
A. N. Omelyanchouk, S. N. Shevchenko, Ya. S. Greenberg +2
We present a detailed theoretical analysis for a system of a superconducting flux qubit coupled to a transmission line resonator. The master equation, accounting incoherent process…
Voltage-current and voltage-flux characteristics of asymmetric high TC DC SQUIDs
I. L. Novikov, Ya. S. Greenberg, V. Schultze +2
We report measurements of transfer functions and flux shifts of 20 on-chip high T DC SQUIDs half of which were made purposely geometrically asymmetric. All of these SQUIDs were…
Quantum theory of the low-frequency linear susceptibility of interferometer-type superconducting qubits
Ya. S. Greenberg, E. Il'ichev
We use the density matrix formalism to analyze the interaction of interferometer-type superconducting qubits with a high quality tank circuit, which frequency is well below the gap…
Flux qubit as a sensor for a magnetometer with quantum limited sensitivity
E. Il'ichev, Ya. S. Greenberg
We propose to use the quantum properties of a superconducting flux qubit in the construction of a magnetometer with quantum limited sensitivity. The main advantage of a flux qubit…
The Voltage-Current Characteristic of high T_c DC SQUID: theory, simulation, experiment
Ya. S. Greenberg, I. L. Novikov
The analytical theory for the voltage-current characteristics of the large inductance (L>100 pH) high-T_c DC SQUIDs that has been developed previously is consistently compared with…
