Dispersive Charge and Flux Qubit Readout as a Quantum Measurement Process
L. Tornberg, G. Johansson
We analyze the dispersive readout of superconducting charge and flux qubits as a quantum measurement process. The measurement oscillator frequency is considered much lower than the…

Readout methods and devices for Josephson-junction-based solid-state qubits
G. Johansson, L. Tornberg, V. S. Shumeiko +1
We discuss the current situation concerning measurement and readout of Josephson-junction based qubits. In particular we focus attention of dispersive low-dissipation techniques in…

Fast quantum limited read-out of a superconducting qubit using a slow oscillator
G. Johansson, L. Tornberg, C. M. Wilson
We describe how to perform fast quantum limited read-out of a solid state qubit biased at its degeneracy point. The method is based on homodyne detection of the phase of a microwav…
