Solving The Quantum Many-Body Hamiltonian Learning Problem with Neural Differential Equations
Timothy Heightman, Edward Jiang, Antonio Acín
Understanding and characterising quantum many-body dynamics remains a significant challenge due to both the exponential complexity required to represent quantum many-body Hamiltoni…
Improved finite-size key rates for discrete-modulated continuous variable quantum key distribution under coherent attacks
Carlos Pascual-García, 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-Rodríguez, Leonardo Zambrano, Antonio Acín +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…
Realistic Bell tests with homodyne measurements
Enky Oudot, Gaël Massé, Xavier Valcarce +1
We analyze Bell inequalities violations in photonic experiments for which the measurement apparatuses are restricted to homodyne measurements. Through numerical optimization of the…
Device-Independent Quantum Key Distribution beyond qubits
Javier Rivera-Dean, Anna Steffinlongo, Neil Parker-Sánchez +2
Device-Independent Quantum Key Distribution (DIQKD) aims to generate secret keys between two parties without relying on trust in their employed devices, imposing strict noise const…
