Dispersive Gate Sensing the Quantum Capacitance of a Point Contact
M. C. Jarratt, A. Jouan, A. C. Mahoney +5
The technique of dispersive gate sensing (DGS) uses a single electrode to readout a qubit by detecting the change in quantum capacitance due to single electron tunnelling. Here, we…
Gate-Sensing Charge Pockets in the Semiconductor Qubit Environment
X. G. Croot, S. J. Pauka, H. Lu +6
We report the use of dispersive gate sensing (DGS) as a means of probing the charge environment of heterostructure-based qubit devices. The DGS technique, which detects small shift…
Experimental bath engineering for quantitative studies of quantum control
A. Soare, H. Ball, D. Hayes +5
We develop and demonstrate a technique to engineer universal unitary baths in quantum systems. Using the correspondence between unitary decoherence due to ambient environmental noi…
Frequency Stabilization of a 369 nm Diode Laser by Nonlinear Spectroscopy of Ytterbium Ions in a Discharge
Michael W Lee, Marie Claire Jarratt, Christian Marciniak +1
We demonstrate stabilisation of an ultraviolet diode laser via Doppler free spectroscopy of Ytterbium ions in a discharge. Our technique employs polarization spectroscopy, which pr…
