Autonomous tuning and charge state detection of gate defined quantum dots
J. Darulová, S. J. Pauka, N. Wiebe +5
Defining quantum dots in semiconductor based heterostructures is an essential step in initializing solid-state qubits. With growing device complexity and increasing number of funct…
A Cryogenic Interface for Controlling Many Qubits
S. J. Pauka, K. Das, R. Kalra +9
A scaled-up quantum computer will require a highly efficient control interface that autonomously manipulates and reads out large numbers of qubits, which for solid-state implementa…
Repairing the Surface of InAs-based Topological Heterostructures
S. J. Pauka, J. D. S. Witt, C. N. Allen +9
Candidate systems for topologically-protected qubits include two-dimensional electron gases (2DEGs) based on heterostructures exhibiting a strong spin-orbit interaction (SOI) and s…
Characterising Quantum Devices at Scale with Custom Cryo-CMOS
S. J. Pauka, K. Das, J. M. Hornibrook +4
We make use of a custom-designed cryo-CMOS multiplexer (MUX) to enable multiple quantum devices to be characterized in a single cool-down of a dilution refrigerator. Combined with…
Radio-frequency methods for Majorana-based quantum devices: fast charge sensing and phase diagram mapping
Davydas Razmadze, Deividas Sabonis, Filip K. Malinowski +9
Radio-frequency (RF) reflectometry is implemented in hybrid semiconductor-superconductor nanowire systems designed to probe Majorana zero modes. Two approaches are presented. In th…
