Quantum control of donor electrons at the Si-SiO2 interface
M. J. Calderon, Belita Koiller, Xuedong Hu +1
Prospects for the quantum control of electrons in the silicon quantum computer architecture are considered theoretically. In particular, we investigate the feasibility of shuttling…
Silicon-based spin and charge quantum computation
Belita Koiller, Xuedong Hu, R. B. Capaz +2
Silicon-based quantum-computer architectures have attracted attention because of their promise for scalability and their potential for synergetically utilizing the available resour…
Quantum electromechanics: Qubits from buckling nanobars
Sergey Savel'ev, Xuedong Hu, Franco Nori
We propose a mechanical qubit based on buckling nanobars--a NEMS so small as to be quantum coherent.To establish buckling nanobars as legitimate candidates for qubits, we calculate…
Spin-Based Quantum Dot Quantum Computing
Xuedong Hu
We present a brief overview of the current theoretical and experimental progresses in the study of quantum dot-based quantum computing schemes, then focus on the spin-based varieti…
Silicon conduction-band effects on shallow donor wavefunctions and donor-pair exchange: An {\it ab initio} theory
R. B. Capaz, Belita Koiller, Xuedong Hu +1
This paper has been withdrawn by the authors. A more complete treatment of the bandstructure effects is forthcoming.
Gate errors in solid state quantum computation
Xuedong Hu, S. Das Sarma
We review our work on the interplay between non-resonant gates and solid state environment in various solid state quantum computer architectures and the resulting gate errors. Part…
