Heralded state preparation in a superconducting qubit
Heralded state preparation superconducting qubit quantum non-demolition
2012/2/27
We demonstrate high-fidelity, quantum non-demolition, single shot readout of a superconducting flux qubit in which the pointer state histograms can be resolved to below one part in 1000. In the weak e...
A superconducting qubit with Purcell protection and tunable coupling
superconducting qubit Purcell protection tunable coupling
2010/10/27
We present a superconducting qubit for the circuit quantum electrodynamics architecture that has a tunable coupling strength g. We show that this coupling strength can be tuned from zero to values tha...
