Dispersive measurement of a semiconductor double quantum dot via 3D integration of a high-impedance TiN resonator
Nathan Holman, D. Rosenberg, D. Yost +5
Spins in semiconductor quantum dots are a candidate for cryogenic quantum processors due to their exceptionally long coherence times. One major challenge to scaling quantum dot spi…
Coherent control and spectroscopy of a semiconductor quantum dot Wigner molecule
J. Corrigan, J. P. Dodson, H. Ekmel Ercan +12
Multi-electron semiconductor quantum dots have found wide application in qubits, where they enable readout and enhance polarizability. However, coherent control in such dots has ty…
Microwave Engineering for Semiconductor Quantum Dots in a cQED Architecture
Nathan Holman, J. P. Dodson, L. F. Edge +4
We develop an engineered microwave environment for coupling high Q superconducting resonators to quantum dots using a multilayer fabrication stack for the dot control wiring. Analy…
Fabrication process and failure analysis for robust quantum dots in silicon
J. P. Dodson, Nathan Holman, Brandur Thorgrimsson +7
We present an improved fabrication process for overlapping aluminum gate quantum dot devices on Si/SiGe heterostructures that incorporates low-temperature inter-gate oxidation, the…
Progress Towards a Capacitively Mediated CNOT Between Two Charge Qubits in Si/SiGe
E. R. MacQuarrie, Samuel F. Neyens, J. P. Dodson +8
Fast operations, an easily tunable Hamiltonian, and a straightforward two-qubit interaction make charge qubits a useful tool for benchmarking device performance and exploring two-q…
