Quantum Magic Reveals CP Phases Invisible to Entanglement in Spin-0 Decays
Nicolas Viaux, Ariel Norambuena, Pedro Orellana
All standard scalar quantum-information measures -- concurrence, negativity, entanglement entropy, the optimized CHSH bound, and quantum Fisher information -- are CP-blind in ideal…

Geometric control of maximal entanglement via bound states in the continuum
Alexis R. Legón, Mario Miranda Rojas, Pedro Orellana +1
Bound states in the continuum (BiCs) convert dissipative open systems into effectively closed quantum subspaces through destructive interference. We show that two identical giant a…

Unconventional Floquet topological phases in the SSH lattice
Dunkan MartÃnez, Yuriko Baba, BenjamÃn Santos +4
Topological materials, known for their edge states robust against local perturbations, hold promise for next-generation quantum technologies, but remain scarce in nature and challe…
