Two-qubit quantum gates with minimal pulse sequences
Ignacio R. Sola, Seokmin Shin, Bo Y. Chang
Working with trapped atoms at close distance to each other, we show that one can implement entangling gates based on non-independent qubits using a single pulse per qubit, or a sin…
Spatiotemporal control of entangling gates on atomic N-qubit systems
Ignacio R. Sola, Seokmin Shin, Bo Y. Chang
We use a novel optimization procedure that includes the temporal and spatial parameters of the pulses acting on arrays of trapped neutral atoms, to prepare entangling gates in N-qu…
Two-qubit atomic gates: Spatio-temporal control of Rydberg interaction
Ignacio R. Sola, Vladimir S. Malinovsky, Jaewook Ahn +2
By controlling the temporal and spatial features of light, we propose a novel protocol to prepare two-qubit entangling gates on atoms trapped at close distance, which could potenti…
Finding, mapping and classifying optimal protocols for two-qubit entangling gates
Ignacio R. Sola, Seokmin Shin, Bo Y. Chang
We characterize the set of optimal protocols for two-qubit entangling gates through a mechanism analysis based on quantum pathways, which allows us to compare and rank the differen…
Nonadiabatic ab initio molecular dynamics including spin-orbit coupling and laser fields
Philipp Marquetand, Martin Richter, Jesús González-Vázquez +2
Nonadiabatic ab initio molecular dynamics (MD) including spin-orbit coupling (SOC) and laser fields is investigated as a general tool for studies of excited-state processes. Up to…
Femtosecond Intersystem Crossing in the DNA Nucleobase Cytosine
Martin Richter, Philipp Marquetand, Jesús González-Vazquez +2
Ab initio molecular dynamics including non-adiabatic and spin-orbit couplings on equal footing is used to unravel the deactivation of cytosine after UV light absorption. Intersyste…
Anti-alignment driven dynamics in the excited states of molecules under strong fields
Sebastián Carrasco, José Rogan, Juan Alejandro Valdivia +1
We develop two novel models of the H molecule and its isotopes from which we assess quantum-mechanically and semi-classically whether the molecule anti-aligns with the field…
Control defeseance by anti-alignment in the excited state
Bo Y. Chang, Seokmin Shin, Jesús González-Vázquez +3
We predict anti-alignment dynamics in the excited state of H2+ or related homonuclear dimers in the presence of a strong field. This effect is a general indirect outcome of the str…
A grid-based Ehrenfest model to study electron-nuclear processes
Bo Y. Chang, Seokmin Shin, Vladimir S. Malinovsky +1
The two-dimensional electron-nuclear Schrödinger equation using soft-core Coulomb potentials has been a cornerstone for modeling and predicting the behavior of one-active-electron…
Tunneling induced electron transfer between separated protons
Patricia Vindel-Zandbergen, Christoph Meier, Ignacio R. Sola
We study electron transfer between two separated nuclei using local control theory. By conditioning the algorithm in a symmetric system formed by two protons, one can favored slow…
Anomalous Rabi oscillations in multilevel quantum systems
B. Y. Chang, I. R. Sola, Vladimir S. Malinovsky
We show that the excitation probability of a state within a manifold of levels undergoes Rabi oscillations with frequency determined by the energy difference between the states and…
Geometrical optimization approach to isomerization: Models and limitations
Bo Y. Chang, Seokmin Shin, Volker Engel +1
We study laser-driven isomerization reactions through an excited electronic state using the recently developed Geometrical Optimization procedure [J. Phys. Chem. Lett. 6, 1724 (201…
Vibrationally-induced electronic population inversion with strong femtosecond pulses
Pablo Sampedro, Bo Y. Chang, Ignacio R. Sola
We discover a new mechanism of electronic population inversion using strong femtosecond pulses, where the transfer is mediated by vibrational motion on a light-induced potential. T…
Lighting the Landscape: Molecular Events Under Dynamic Stark Shifts
Bo Y. Chang, Ignacio R. Sola, Seokmin Shin
A new perspective on how to manipulate molecules by means of very strong laser pulses is emerging with insights from the so-called light-induced potentials, which are the adiabatic…

Pablo Sampedro, Bo Y. Chang, Ignacio R. Sola
Using numerical simulations of two-photon electronic absorption with femtosecond pulses in Na we show that: i) it is possible to avoid the characteristic saturation or dumped R…
Engineering the initial state in broadband population inversion
Bo Y. Chang, Sheokmin Shin, Ignacio R. Sola
Quantum systems with sublevel structures prevent full population inversion from one manifold of sublevels to the other using strong ultrafast resonant pulses. In this work we expla…
