Lie-Algebraic Classical Simulation of Bosonic Systems Beyond Gaussian Dynamics
Adelina Bärligea, Timothy Heightman, Jakob S. Kottmann +1
Classical simulability is ultimately determined by both the dynamics of a quantum system and the observables being evaluated. Lie-algebraic simulation exploits the latter to make e…
Moment Optimization in the Navascués-Pironio-AcÃn Hierarchy
Francesco Flora, Losel Matos, Tim Heightman +3
The paper introduces a scalable method for selecting operator moments in the Navascués‑Pironio‑Acín (NPA) hierarchy using combinatorial optimization techniques, demonstrating impro…
Swap Network Augmented Ansätze on Arbitrary Connectivity
Teodor Parella-Dilmé, Jakob S. Kottmann, Antonio AcÃn
Efficient parametrizations of quantum states are essential for trainable hybrid classical-quantum algorithms. A key challenge in their design consists in adapting to the available…
Improved finite-size key rates for discrete-modulated continuous variable quantum key distribution under coherent attacks
Carlos Pascual-GarcÃa, Stefan Bäuml, Mateus Araújo +2
Continuous variable quantum key distribution (CVQKD) with discrete modulation combines advantages of CVQKD, such as the implementability using readily available technologies, with…
Boosting projective methods for quantum process and detector tomography
Júlia Barberà -RodrÃguez, Leonardo Zambrano, Antonio AcÃn +1
We introduce two methods for quantum process and detector tomography. In the quantum process tomography method, we develop an analytical procedure for projecting the linear inversi…
Qudit-inspired optimization for graph coloring
David Jansen, Timothy Heightman, Luke Mortimer +2
We introduce a quantum-inspired algorithm for graph coloring problems (GCPs) that utilizes qudits in a product state, with each qudit representing a node in the graph and parameter…
