Counterdiabatic quasi-Floquet control for the generation of entangled BICs using giant atoms
Alexis R. Legón, Pedro Orellana, Ariel Norambuena
Bound states in the continuum (BICs) provide a mechanism for preserving entanglement in waveguide quantum electrodynamics. Here, using quantum control techniques in a configuration…
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…
Memory effects in pulsed optomechanical systems
Hachisko Tapia-Maureira, Bing He, Massimiliano Di Ventra +1
Memory, understood as time non-locality, is a fundamental property of any physical system, whether classical or quantum, and has important applications in a wide variety of technol…
