A quantum dot-based frequency multiplier

G. A. Oakes, L. Peri, L. Cochrane +8

Silicon offers the enticing opportunity to integrate hybrid quantum-classical computing systems on a single platform. For qubit control and readout, high-frequency signals are requ…

The effect of split gate size on the electrostatic potential and 0.7 anomaly within one-dimensional quantum wires on a modulation doped GaAs/AlGaAs heterostructure

L. W. Smith, H. Al-Taie, A. A. J. Lesage +9

We study 95 split gates of different size on a single chip using a multiplexing technique. Each split gate defines a one-dimensional channel on a modulation-doped GaAs/AlGaAs heter…

A low-temperature device architecture for the statistical study of electrical characteristics of 256 quantum devices

H. Al-Taie, L. W. Smith, B. Xu +7

Research in the field of low-temperature electronics is limited by the small number of electrical contacts available on cryogenic set ups. This not only restricts the number of dev…

Vortex detection and quantum transport in mesoscopic graphene Josephson junction arrays

C. L. Richardson, S. D. Edkins, G. R. Berdiyorov +9

We investigate mesoscopic Josephson junction arrays created by patterning superconducting disks on monolayer graphene, concentrating on the high- regime of these devices and…

Non-Ohmic behavior of carrier transport in highly disordered graphene

Shun-Tsung Lo, Chiashain Chuang, R. K. Puddy +3

We report measurements of disordered graphene probed by both a high electric field and a high magnetic field. By apply a high source-drain voltage Vsd, we are able to study the cur…

Cryogenic on-chip multiplexer for the study of quantum transport in 256 split-gate devices

H. Al-Taie, L. W. Smith, B. Xu +7

We present a multiplexing scheme for the measurement of large numbers of mesoscopic devices in cryogenic systems. The multiplexer is used to contact an array of 256 split gates on…
