Stokes-anti-Stokes correlated photon properties akin to photonic Cooper pairs
Filomeno S. de Aguiar Junior, Andre Saraiva, Marcelo F. Santos +6
Photons interact with each other in condensed matter through the same mechanism that forms Cooper pairs in superconductors -- the exchange of virtual phonons [PRL 119, 193603 (2017…
Adequacy of Si:P Chains as Fermi-Hubbard Simulators
Amintor Dusko, Alain Delgado, André Saraiva +1
The challenge of simulating many-body models with analogue physical systems requires both experimental precision and very low operational temperatures. Atomically precise placement…
Photonic Counterparts of Cooper Pairs
Andre Saraiva, Filomeno S. de Aguiar Junior, Reinaldo de Melo e Souza +5
The microscopic theory of superconductivity raised the disruptive idea that electrons couple through the elusive exchange of virtual phonons, overcoming the strong Coulomb repulsio…
Donors in Ge as Qubits: Establishing Physical Attributes
A. Baena, A. L. Saraiva, Marcos G. Menezes +1
Quantum electronic devices at the single impurity level demand an understanding of the physical attributes of dopants at an unprecedented accuracy. Germanium-based technologies hav…
Anderson Localization of Electrons in Silicon Donor Chains
Amintor Dusko, Andre Saraiva, Belita Koiller
We construct a model to study the localization properties of nanowires of dopants in silicon (Si) fabricated by precise ionic implantation or STM lithography. Experiments have show…
Donor Wavefunctions in Si Gauged by STM Images
A. L. Saraiva, J. Salfi, J. Bocquel +5
The triumph of effective mass theory in describing the energy spectrum of dopants does not guarantee that the model wavefunctions will withstand an experimental test. Such wavefunc…
Transport through an impurity tunnel coupled to a Si/SiGe quantum dot
Ryan H. Foote, Daniel R. Ward, J. R. Prance +8
Achieving controllable coupling of dopants in silicon is crucial for operating donor-based qubit devices, but it is difficult because of the small size of donor-bound electron wave…
Dispersively detected Pauli Spin-Blockade in a Silicon Nanowire Field-Effect Transistor
A. C. Betz, R. Wacquez, M. Vinet +5
We report the dispersive readout of the spin state of a double quantum dot formed at the corner states of a silicon nanowire field-effect transistor. Two face-to-face top-gate elec…
Theory of one and two donors in Silicon
A. L. Saraiva, A. Baena, M. J. Calderón +1
We provide here a roadmap for modeling silicon nano-devices with one or two group V donors (D). We discuss systems containing one or two electrons, that is, D^0, D^-, D_2^+ and D_2…
An Exchange-Coupled Donor Molecule in Silicon
M. Fernando Gonzalez-Zalba, André Saraiva, Dominik Heiss +3
Donors in silicon, conceptually described as hydrogen atom analogues in a semiconductor environment, have become a key ingredient of many "More-than-Moore" proposals such as quantu…
Splitting Valleys in Si/SiO: Identification and Control of Interface States
Amintor Dusko, A. L. Saraiva, Belita Koiller
Interface states in a silicon/barrier junction break the silicon valley degeneracy near the interface, a desirable feature for some Si quantum electronics applications. Within a mi…
Genetic Design of Enhanced Valley Splitting towards a Spin Qubit in Silicon
Lijun Zhang, Jun-Wei Luo, A. L. Saraiva +2
Electronic spins in Silicon (Si) are rising contenders for qubits -- the logical unit of quantum computation-- owing to its outstanding spin coherence properties and compatibility…
Impact of the valley degree of freedom on the control of donor electrons near a Si/SiO_2 interface
A. Baena, A. L. Saraiva, Belita Koiller +1
We analyze the valley composition of one electron bound to a shallow donor close to a Si/barrier interface as a function of an applied electric field. A full six-valley effective m…
Valley-based noise-resistant quantum computation using Si quantum dots
Dimitrie Culcer, A. L. Saraiva, Belita Koiller +2
We devise a platform for noise-resistant quantum computing using the valley degree of freedom of Si quantum dots. The qubit is encoded in two polarized (1,1) spin-triplet states wi…
Extended interface states enhance valley splitting in Si/SiO2
A. L. Saraiva, Belita Koiller, Mark Friesen
Interface disorder and its effect on the valley degeneracy of the conduction band edge remains among the greatest theoretical challenges for understanding the operation of spin qub…
