Silicon Quantum Dots with Counted Antimony Donor Implants
M. Singh, J. L. Pacheco, D. Perry +11
Deterministic control over the location and number of donors is crucial to donor spin quantum bits (qubits) in semiconductor based quantum computing. In this work, a focused ion be…
Cryogenic preamplification of a single-electron-transistor using a silicon-germanium heterojunction-bipolar-transistor
M. J. Curry, T. D. England, N. C. Bishop +6
We examine a silicon-germanium heterojunction bipolar transistor (HBT) for cryogenic pre-amplification of a single electron transistor (SET). The SET current modulates the base cur…
Transport spectroscopy of low disorder silicon tunnel barriers with and without Sb implants
A. Shirkhorshidian, N. C. Bishop, J. Dominguez +4
We present transport measurements of silicon MOS split gate structures with and without Sb implants. We observe classical point contact (PC) behavior that is free of any pronounced…
Efficient self-consistent quantum transport simulator for quantum devices
Xujiao Gao, Denis Mamaluy, Erik Nielsen +6
We present a self-consistent one-dimensional (1D) quantum transport simulator based on the Contact Block Reduction (CBR) method, aiming for very fast and robust transport simulatio…
QCAD Simulation and Optimization of Semiconductor Quantum Dots
Xujiao Gao, Erik Nielsen, Richard P. Muller +5
We present the Quantum Computer Aided Design (QCAD) simulator that targets modeling multi-dimensional quantum devices, particularly silicon multi-quantum dots (QDs) developed for q…
Spontaneous emission in a silicon charge qubit
Khoi T. Nguyen, N. Tobias Jacobson, Michael P. Lilly +6
The interaction between a qubit and its environment provides a channel for energy relaxation which has an energy-dependent timescale governed by the specific coupling mechanism. We…
