Domain wall in a chiral p-wave superconductor: a pathway for electrical current

I. Serban, B. Beri, A. R. Akhmerov +1

Superconductors with p+ip pairing symmetry are characterized by chiral edge states, but these are difficult to detect in equilibrium since the resulting magnetic field is screened…

Relaxation of a qubit measured by a driven Duffing oscillator

I. Serban, M. I. Dykman, F. K. Wilhelm

We investigate the relaxation of a superconducting qubit for the case when its detector, the Josephson bifurcation amplifier, remains latched in one of its two (meta)stable states…

Qubit decoherence due to detector switching

I. Serban, F. K. Wilhelm

We provide insight into the qubit measurement process involving a switching type of detector. We study the switching-induced decoherence during escape events. We present a simple m…

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…
