Proposal for generating and detecting multi-qubit GHZ states in circuit QED
Lev S. Bishop, L. Tornberg, D. Price +8
We propose methods for the preparation and entanglement detection of multi-qubit GHZ states in circuit quantum electrodynamics. Using quantum trajectory simulations appropriate for…
Randomized benchmarking and process tomography for gate errors in a solid-state qubit
J. M. Chow, J. M. Gambetta, L. Tornberg +7
We present measurements of single-qubit gate errors for a superconducting qubit. Results from quantum process tomography and randomized benchmarking are compared with gate errors o…
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…
