Fast and Smooth Quantum Unitary Control of High-Dimensional Spin-Qudits via a Shooting Technique
Paul-Louis Etienney, Denis Janković, Killian Lutz +3
High-fidelity quantum control is a cornerstone of scalable quantum technologies. We introduce a shooting-based optimization framework that generates smooth, experimentally realisti…
The hyperfine interaction as a probe of the microscopic structure of the atomic nucleus
Denis Janković, Jean-Gabriel Hartmann, Johann Bartel +3
The study of highly charged electronic and muonic hydrogen-like ions, provides an intriguing way to probe the internal structure of their atomic nuclei. In this work, we use nuclea…
Quantum Optimal Control Using MAGICARP: Combining Pontryagin's Maximum Principle and Gradient Ascent
Denis Janković, Jean-Gabriel Hartmann, Paul-Louis Etienney +3
We introduce the MAGICARP algorithm, a numerical optimization method for quantum optimal control problems that combines the structure provided by Pontryagin's Maximum Principle (PM…
Elucidating the Physical and Mathematical Properties of the Prouhet-Thue-Morse Sequence in Quantum Computing
Denis Janković, Rémi Pasquier, Jean-Gabriel Hartmann +1
This study explores the applications of the Prouhet-Thue-Morse (PTM) sequence in quantum computing, highlighting its mathematical elegance and practical relevance. We demonstrate t…
Full- and low-rank exponential Euler integrators for the Lindblad equation
Hao Chen, Alfio Borzì, Denis Janković +2
The Lindblad equation is a widely used quantum master equation to model the dynamical evolution of open quantum systems whose states are described by density matrices. These soluti…
Nonlinearity of the Fidelity in Open Qudit Systems: Gate and Noise Dependence in High-dimensional Quantum Computing
Jean-Gabriel Hartmann, Denis Janković, Rémi Pasquier +2
High-dimensional quantum computing has generated significant interest due to its potential to address scalability and error correction challenges faced by traditional qubit-based s…
Noisy Qudit vs Multiple Qubits : Conditions on Gate Efficiency for Enhancing Fidelity
Denis Janković, Jean-Gabriel Hartmann, Mario Ruben +1
Today, multiple new platforms are implementing qudits, -level quantum bases of information, for Quantum Information Processing (QIP). It is therefore crucial to study their effi…
Chaos and Scrambling in Quantum Small Worlds
Jean-Gabriel Hartmann, Jeff Murugan, Jonathan P. Shock
Quantum small-worlds are quantum many-body systems that interpolate between completely ordered (nearest-neighbour, next-to-nearest-neighbour etc.) and completely random interaction…
