Directional Motional Control via Engineered Conical Intersections in Trapped Rydberg Ions
Abdessamad Belfakir, Yousra Bouasria, Herschel Rabitz +1
We demonstrate coherent control of motional dynamics in trapped Rydberg ions engineered to exhibit a conical intersection between adiabatic potential-energy surfaces. Using quantum…
A Fundamental Bound for Robust Quantum Gate Control
Robert L. Kosut, Daniel A. Lidar, Herschel Rabitz
We derive a universal performance limit for coherent quantum control in the presence of modeled and unmodeled uncertainties. For any target unitary that is implementable in the…
Stability and quasi-Periodicity of Many-Body Localized Dynamics
Peyman Azodi, Herschel A. Rabitz
The connection between entanglement dynamics and non-equilibrium statistics in isolated many-body quantum systems has been established both theoretically and experimentally. Many-B…
Mechanism behind creating qubit gates expressed as interfering quantum pathway amplitudes
Michael Kasprzak, Gaurav Bhole, Herschel Rabitz
Hamiltonian encoding was introduced as a technique for revealing the mechanism of controlled quantum systems. It does so by decomposing the evolution into pathways between the comp…
Entanglement Propagation in Integrable Heisenberg Chains from a New Lens
Peyman Azodi, Herschel A Rabitz
The exact single-magnon entanglement evolution in Heisenberg chains is obtained using the Quantum Correlation Transfer Function (QCTF) formulation. A dual, i.e., frequency and time…
Emergence of Light Cones in Long-range Interacting Spin Chains Is Due to Destructive Interference
Peyman Azodi, Herschel A. Rabitz
Despite extensive research on long-range interacting quantum systems, the physical mechanism responsible for the emergence of light cones remains unidentified. This work presents a…
