Variational Quantum Models for Knowledge Graph Embeddings on NISQ Devices

Guido Bellomo, Martín Santesteban, Patricio Bruno +2

Variational Quantum Algorithms (VQAs) combine quantum circuits with classical optimization to tackle problems that may benefit from the capabilities of near-term quantum hardware.…

Fundamental Limits to Cat-Code Qubits from Chaos-Assisted Tunneling

Lionel E. Martínez, Ignacio García-Mata, Diego A. Wisniacki

We show that chaos-assisted tunneling (CAT) imposes an intrinsic limit to the protection of Kerr-cat qubits. In the static effective description, tunneling between the quasidegener…

Is the matrix completion of reduced density matrices unique?

Gustavo E. Massaccesi, Ofelia B. Oña, Luis Lain +4

Reduced density matrices are central to describing observables in many-body quantum systems. In electronic structure theory, the two-particle reduced density matrix (2-RDM) suffice…

A First-Principles Thermodynamic Uncertainty Relation for Shortcuts to Adiabaticity

Guillermo Perna, Federico Centrone, Esteban Calzetta

We study the fundamental limitations of implementing time-dependent Hamiltonian protocols when ''time'' is provided by a quantum clock rather than an external classical parameter.…

Ruelle-Pollicott Decay of Out-of-Time-Order Correlators in Many-Body Systems

Jerónimo Duarte, Ignacio García-Mata, Diego A. Wisniacki

The out-of-time-order correlator (OTOC) quantifies information scrambling in quantum systems and serves as a key diagnostic of quantum chaos. In one-body systems with a classical c…

Ergotropic characterization of continuous variable entanglement

Beatriz Polo-Rodríguez, Federico Centrone, Gerardo Adesso +1

Continuous-variable quantum thermodynamics in the Gaussian regime provides a promising framework for investigating the energetic role of quantum correlations, particularly in optic…
