Quantum coherence and special states
Coherent and cat-like quantum states, and phase-space tools to diagnose and control quantum coherence.
- Coherent states
- Schrödinger-cat states
- Phase-space methods for quantum diagnostics
From fundamental quantum physics to quantum materials and devices
QUISANTECH (FQM 420) brings together researchers from different institutions to study how coherence, symmetries and topology govern quantum systems. We use information-theoretic tools, phase-space methods and algebraic techniques to characterize quantum phases and design noise-resilient quantum technologies.
Location: Faculty of Science, University of Granada · Collaborations: National and international partners.
QUISANTECH (FQM 420) is an Andalusian research group devoted to the study of quantum systems, using both analytical and numerical techniques.
Our research explores how coherence, symmetry principles, topology and noise shape quantum behaviour in systems ranging from few-body platforms to complex materials. We combine information-theoretic tools, phase-space methods and algebraic techniques to obtain unified insights into quantum phases, dynamics and control.
We work along five interconnected lines: quantum coherence and special states; quantum phases, transitions and information; 2D topological Dirac materials; high-dimensional unitary symmetries; and noise-resilient quantum technologies.
