Quantum nondemolition-like, fast measurement scheme for a superconducting qubit
I. Serban, B. L. T. Plourde, F. K. Wilhelm
We present a measurement protocol for a flux qubit coupled to a dc-Superconducting QUantum Interference Device (SQUID), representative of any two-state system with a controllable c…
Dynamical tunneling in macroscopic systems
I. Serban, F. K. Wilhelm
We investigate macroscopic dynamical quantum tunneling (MDQT) in the driven Duffing oscillator, charateristic for Josephson junction physics and nanomechanics. Under resonant condi…
Phase-space theory for dispersive detectors of superconducting qubits
I. Serban, E. Solano, F. K. Wilhelm
Motivated by recent experiments, we study the dynamics of a qubit quadratically coupled to its detector, a damped harmonic oscillator. We use a complex-environment approach, explic…
Optimal control of time-dependent targets
I. Serban, J. Werschnik, E. K. U. Gross
In this work, we investigate how and to which extent a quantum system can be driven along a prescribed path in Hilbert space by a suitably shaped laser pulse. To calculate the opti…
