Strain-induced spin resonance shifts in silicon devices
J. J. Pla, A. Bienfait, G. Pica +8
In spin-based quantum information processing devices, the presence of control and detection circuitry can change the local environment of a spin by introducing strain and electric…
Theory of single and two-qubit operations with donor-bound electron spins in germanium
Giuseppe Pica, Brendon W. Lovett
The possibility of quantum computing with spins in germanium nanoscale transistors has recently attracted interest since it promises highly tuneable qubits that have encouraging co…
Surface code architecture for donors and dots in silicon with imprecise and nonuniform qubit couplings
G. Pica, B. W. Lovett, R. N. Bhatt +2
A scaled quantum computer with donor spins in silicon would benefit from a viable semiconductor framework and a strong inherent decoupling of the qubits from the noisy environment.…
Quadrupole Shift of Nuclear Magnetic Resonance of Donors in Silicon at Low Magnetic Field
P. A. Mortemousque, S. Rosenius, G. Pica +8
Shifts from the expected nuclear magnetic resonance frequencies of antimony and bismuth donors in silicon of greater than a megahertz are observed in electrically detected magnetic…
Hyperfine Stark effect of shallow donors in silicon
G. Pica, G. Wolfowicz, M. Urdampilleta +9
We present a complete theoretical treatment of Stark effects in doped silicon, whose predictions are supported by experimental measurements. A multi-valley effective mass theory, d…
Exchange coupling between silicon donors: the crucial role of the central cell and mass anisotropy
G. Pica, B. W. Lovett, R. N Bhatt +1
Donors in silicon are now demonstrated as one of the leading candidates for implementing qubits and quantum information processing. Single qubit operations, measurements and long c…
