Impact of measurement backaction on nuclear spin qubits in silicon
S. Monir, E. N. Osika, S. K. Gorman +7
Phosphorus donor nuclear spins in silicon couple weakly to the environment making them promising candidates for high-fidelity qubits. The state of a donor nuclear spin qubit can be…
Superexchange coupling of donor qubits in silicon
Mushita M. Munia, Serajum Monir, Edyta N. Osika +2
Atomic engineering in a solid-state material has the potential to functionalize the host with novel phenomena. STM-based lithographic techniques have enabled the placement of indiv…
Spin-photon coupling for atomic qubit devices in silicon
Edyta N. Osika, Sacha Kocsis, Yu-Ling Hsueh +6
Electrically addressing spin systems is predicted to be a key component in developing scalable semiconductor-based quantum processing architectures, to enable fast spin qubit manip…
Spin-valley resolved photon-assisted tunneling in carbon nanotube double quantum dots
E. N. Osika, B. Szafran
We consider the photon-assisted tunneling (PAT) and the Landau-Zener-Stueckelberg (LZS) interference for double quantum dots induced electrostatically along a semiconducting carbon…
Spin-valley dynamics of electrically driven ambipolar carbon-nanotube quantum dots
E. N. Osika, A. Chacón, M. Lewenstein +1
An ambipolar - double quantum dot defined by potential variation along a semiconducting carbon-nanotube is considered. We focus on the (1e,1h) charge configuration with a sin…
Wannier-Bloch approach to localization in high harmonics generation in solids
Edyta N. Osika, Alexis Chacón, Lisa Ortmann +7
Emission of high-order harmonics from solids provides a new avenue in attosecond science. On one hand, it allows to investigate fundamental processes of the non-linear response of…
Electronic structure of (1e,1h) states of carbon nanotube quantum dots
E. N. Osika, B. Szafran
We provide an atomistic tight-binding description of a few carriers confined in ambipolar (n-p) double quantum dots defined in a semiconducting carbon nanotube. We focus our attent…
Spin-orbit interaction in bent carbon nanotubes: resonant spin transitions
E. N. Osika, B. Szafran
We develop an effective tight-binding Hamiltonian for spin-orbit (SO) interaction in bent carbon nanotubes (CNT) for the electrons forming the bonds between the nearest neighbo…
Two-electron n-p double quantum dots in carbon nanotubes
E. N. Osika, B. Szafran
We consider electron states in n-p double quantum dots defined in a semiconducting carbon nanotube (CNT) by an external potential. We describe formation of extended single-electron…
Tight-binding simulations of electrically driven spin-valley transitions in carbon nanotube quantum dots
E. N. Osika, A. Mreńca, B. Szafran
We describe dynamics of spin and valley transitions driven by alternating electric fields in quantum dots defined electrostatically within semiconducting carbon nanotubes (CNT). We…
Simulations of electric-dipole spin resonance for spin-orbit-coupled quantum dots in Overhauser field: fractional resonances and selection rules
E. N. Osika, B. Szafran, M. P. Nowak
We consider spin rotations in single- and two-electron quantum dots that are driven by external AC electric field with two mechanisms that couple the electron spatial motion and th…
