Non-adiabatic single-electron pump in a dopant-free GaAs/AlGaAs 2DEG

B. Buonacorsi, F. Sfigakis, A. Shetty +7

We have realized quantized charge pumping using non-adiabatic single-electron pumps in dopant-free GaAs two-dimensional electron gases (2DEGs). The dopant-free III-V platform allow…

Optimizing lateral quantum dot geometries for reduced exchange noise

Brandon Buonacorsi, Marek Korkusinski, Bohdan Khromets +1

For electron spin qubits in quantum dots, reducing charge noise sensitivity is a critical step in achieving fault tolerant two-qubit gates mediated by the exchange interaction. Thi…

Simulated coherent electron shuttling in silicon quantum dots

Brandon Buonacorsi, Benjamin Shaw, Jonathan Baugh

Shuttling of single electrons in gate-defined silicon quantum dots is numerically simulated. A minimal gate geometry without explicit tunnel barrier gates is introduced, and used t…

On the freedom in representing quantum operations

Junan Lin, Brandon Buonacorsi, Raymond Laflamme +1

We discuss the effects of a gauge freedom in representing quantum information processing devices, and its implications for characterizing these devices. We demonstrate with experim…

Network architecture for a topological quantum computer in silicon

Brandon Buonacorsi, Zhenyu Cai, Eduardo B. Ramirez +7

A design for a large-scale surface code quantum processor based on a node/network approach is introduced for semiconductor quantum dot spin qubits. The minimal node contains only 7…
