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…

Measurements of capacitive coupling within a quadruple quantum dot array
Samuel F. Neyens, E. R. MacQuarrie, J. P. Dodson +9
We present measurements of the capacitive coupling energy and the inter-dot capacitances in a linear quadruple quantum dot array in undoped Si/SiGe. With the device tuned to a regi…

Low-frequency charge noise in Si/SiGe quantum dots
Elliot J. Connors, JJ Nelson, Haifeng Qiao +2
Electron spins in silicon have long coherence times and are a promising qubit platform. However, electric field noise in semiconductors poses a challenge for most single- and multi…
