Probabilistic motional averaging
D. S. Karpov, V. Y. Monarkha, D. Szombati +6
In a continuous measurement scheme a spin-1/2 particle can be measured and simultaneously driven by an external resonant signal. When the driving is weak, it does not prevent the p…
Amplification and attenuation of a probe signal by doubly-dressed states
S. N. Shevchenko, G. Oelsner, Ya. S. Greenberg +6
We analyse a system composed of a qubit coupled to electromagnetic fields of two high quality quantum oscillators. Particular realization of such a system is the superconducting qu…
Noise-spectroscopy of multiqubit systems: Determining all their parameters by applying an external classical noise
S. Savel'ev, A. M. Zagoskin, A. N. Omelyanchouk +1
Imagine that you have several sets of two coupled qubits, but you do not know the parameters of their Hamitonians. How to determine these without resorting to the usual spectroscop…
Two-qubit parametric amplifier: large amplification of weak signals
S. Savel'ev, A. M. Zagoskin, A. L. Rakhmanov +3
Using numerical simulations, we show that two coupled qubits can amplify a weak signal about hundredfold. This can be achieved if the two qubits are biased simultaneously by this w…
Multiphoton transitions in Josephson-junction qubits (Review Article)
S. N. Shevchenko, A. N. Omelyanchouk, E. Il'ichev
Two basic physical models, a two-level system and a harmonic oscillator, are realized on the mesoscopic scale as coupled qubit and resonator. The realistic system includes moreover…
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…
