Towards the Scalable Fabrication of thin-film Superconducting Parametric Amplifiers
Abdallah El Kass, Kevin A. F. Simoes, Cassandra Chua +3
Kinetic inductance travelling-wave parametric amplifiers (KTWPAs) are emerging as core components in many applications where wideband cryogenic rf amplification at or near the quan…
Interferometric Single-Shot Parity Measurement in an InAs-Al Hybrid Device
Morteza Aghaee, Alejandro Alcaraz Ramirez, Zulfi Alam +159
The fusion of non-Abelian anyons or topological defects is a fundamental operation in measurement-only topological quantum computation. In topological superconductors, this operati…
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…
On-Chip Microwave Quantum Hall Circulator
A. C. Mahoney, J. I. Colless, S. J. Pauka +6
Circulators are non-reciprocal circuit elements integral to technologies including radar systems, microwave communication transceivers, and the readout of quantum information devic…
Cryogenic Control Architecture for Large-Scale Quantum Computing
J. M. Hornibrook, J. I. Colless, I. D. Conway Lamb +8
Solid-state qubits have recently advanced to the level that enables them, in-principle, to be scaled-up into fault-tolerant quantum computers. As these physical qubits continue to…
Modular Cryogenic Interconnects for Multi-Qubit Devices
J. I. Colless, D. J. Reilly
We have developed a modular interconnect platform for the control and readout of multiple solid-state qubits at cryogenic temperatures. The setup provides 74 filtered dc-bias conne…
Frequency Multiplexing for Readout of Spin Qubits
J. M. Hornibrook, J. I. Colless, A. C. Mahoney +5
We demonstrate a low loss, chip-level frequency multiplexing scheme for readout of scaled-up spin qubit devices. By integrating separate bias tees and resonator circuits on-chip fo…
Stimulated Phonon Emission in a Driven Double Quantum Dot
J. I. Colless, X. G. Croot, T. M. Stace +5
The compound semiconductor gallium arsenide (GaAs) provides an ultra-clean platform for storing and manipulating quantum information, encoded in the charge or spin states of electr…
Cryogenic High-Frequency Readout and Control Platform for Spin Qubits
J. I. Colless, D. J. Reilly
We have developed a cryogenic platform for the control and readout of spin qubits that comprises a high density of dc and radio frequency sample interconnects based on a set of cou…
