Stable electroluminescence in ambipolar dopant-free lateral p-n junctions
Lin Tian, Francois Sfigakis, Arjun Shetty +11
Dopant-free lateral p-n junctions in the GaAs/AlGaAs material system have attracted interest due to their potential use in quantum optoelectronics (e.g., optical quantum computers…
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…
Effects of biased and unbiased illuminations on dopant-free GaAs/AlGaAs 2DEGs
A. Shetty, F. Sfigakis, W. Y. Mak +16
Illumination is performed at low temperature on dopant-free two-dimensional electron gases (2DEGs) of varying depths, under unbiased (gates grounded) and biased (gates at a positiv…
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…
Estimating the coherence of noise in quantum control of a solid-state qubit
Guanru Feng, Joel J. Wallman, Brandon Buonacorsi +6
To exploit a given physical system for quantum information processing, it is critical to understand the different types of noise affecting quantum control. Distinguishing coherent…
