Rapid Charge Stability Diagram Generation from Device-level Modeling of Semiconductor Quantum Dots
Ron Nodel, David W. Kanaar, Connor Nasseraddin +5
Self-consistent Schrödinger-Poisson calculations are a powerful tool for predicting the behavior of layered semiconductor quantum dot devices. However, characterization of charge s…
Silicon-Germanium Heterostructures with Enhanced Valley Splitting for Spin Qubits
David W. Kanaar, Efrain Martinez, Peihong Zhang +1
Achieving valley splittings well in excess of the thermal energy of electrons and avoiding valley excitations is essential for the consistent initialization, operation and readout…
Fast charge noise sensing using a spectator valley state in a singlet-triplet qubit
David W. Kanaar, Yasuo Oda, Mark F. Gyure +1
Semiconductor spin qubits are a promising platform for quantum computing but remain vulnerable to charge noise. Accurate, in situ measurement of charge noise could enable closed-lo…
Proposed real-time charge noise measurement via valley state reflectometry
David W. Kanaar, H. Ekmel Ercan, Mark F. Gyure +1
We theoretically propose a method to perform in situ measurements of charge noise during logical operations in silicon quantum dot spin qubits. Our method does not require ancillar…
Robust shaped pulses for arrays of superconducting or semiconductor spin qubits with fixed Ising coupling
David W. Kanaar, J. P. Kestner
A major current challenge in solid-state quantum computing is to scale qubit arrays to a larger number of qubits. This is hampered by the complexity of the control wiring for the l…
Neural-network-designed three-qubit gates robust against charge noise and crosstalk in silicon
David W. Kanaar, J. P. Kestner
Spin qubits in semiconductor quantum dots are a promising platform for quantum computing, however scaling to large systems is hampered by crosstalk and charge noise. Crosstalk here…
Nonadiabatic quantum control of quantum dot arrays with fixed exchange using Cartan decomposition
David W. Kanaar, Utkan Güngördü, J. P. Kestner
In semiconductor spin qubits which typically interact through short-range exchange coupling, shuttling of spin is a practical way to generate quantum operations between distant qub…
Two-qubit CZ gates robust against charge noise in silicon while compensating for crosstalk using neural network
David W. Kanaar, Utkan Güngördü, J. P. Kestner
The fidelity of two-qubit gates using silicon spin qubits is limited by charge noise. When attempting to dynamically compensate for charge noise using local echo pulses, crosstalk…
Single-tone pulse sequences and robust two-tone shaped pulses for three silicon spin qubits with always-on exchange
David W. Kanaar, Sidney Wolin, Utkan Güngördü +1
Quantum computation requires high-fidelity single-qubit and two-qubit gates on a scalable platform. Silicon spin qubits are a promising platform toward realization of this goal. In…
