Robust optimal control of interacting multi-qubit systems for quantum sensing
Nguyen H. Le, Max Cykiert, Eran Ginossar
Realising high fidelity entangled states in controlled quantum many-body systems is challenging due to experimental uncertainty in a large number of physical quantities. We develop…
Scalable and robust quantum computing on qubit arrays with fixed coupling
Nguyen H. Le, Max Cykiert, Eran Ginossar
We propose a scheme for scalable and robust quantum computing on two-dimensional arrays of qubits with fixed longitudinal coupling. This opens the possibility for bypassing the dev…
Position-controlled functionalization of vacancies in silicon by single-ion implanted germanium atoms
Simona Achilli, Nguyen H. Le, Guido Fratesi +7
Special point defects in semiconductors have been envisioned as suitable components for quantum-information technology. The identification of new deep centers in silicon that can b…
Rydberg Entangling Gates in Silicon
Eleanor Crane, Alexander Schuckert, Nguyen H. Le +1
In this paper, we propose a new Rydberg entangling gate scheme which we demonstrate theoretically to have an order of magnitude improvement in fidelities and speed over existing pr…
Topological phases of a dimerized Fermi-Hubbard model for semiconductor nano-lattices
Nguyen H. Le, Andrew J. Fisher, Neil J. Curson +1
Motivated by recent advances in fabricating artificial lattices in semiconductors and their promise for quantum simulation of topological materials, we study the one-dimensional di…
Optically Controlled Entangling Gates in Randomly Doped Silicon
Eleanor Crane, Thomas Crane, Nguyen H. Le +2
Randomly-doped silicon has many competitive advantages for quantum computation; not only is it fast to fabricate but it could naturally contain high numbers of qubits and logic gat…
Giant non-linear susceptibility of hydrogenic donors in silicon and germanium
Nguyen H. Le, Grigory V. Lanskii, G. Aeppli +1
Implicit summation is a technique for the conversion of sums over intermediate states in multiphoton absorption and the high-order susceptibility in hydrogen into simple integrals.…
Excited states of defect lines in silicon: A first-principles study based on hydrogen cluster analogues
W. Wu, P. T. Greenland, A. J. Fisher +3
Excited states of a single donor in bulk silicon have previously been studied extensively based on effective mass theory. However, a proper theoretical description of the excited s…
Extended Hubbard model for mesoscopic transport in donor arrays in silicon
Nguyen H. Le, Andrew J. Fisher, Eran Ginossar
Arrays of dopants in silicon are promising platforms for the quantum simulation of the Fermi-Hubbard model. We show that the simplest model with only on-site interaction is insuffi…
