Spectral evolution of two-photon emission in microresonators
Francesca Famà, Stefano Dello Russo, Stefano Giaccari +14
High-Q silicon nitride microresonators are versatile sources for generating photon pairs via four-wave mixing. We investigate the spectral coherence of this process, tracking the t…
Universal Protection of Quantum States from Decoherence
Francesco Atzori, Salvatore Virzì, Francesco Devecchi +6
The fragility of quantum coherence fundamentally limits the scalability of quantum technologies, as unavoidable environmental interactions induce decoherence and rapidly degrade qu…
Experimental Test of Nonlocality Limits from Relativistic Independence
Francesco Atzori, Salvatore Virzì, Enrico Rebufello +9
Quantum correlations, like entanglement, represent the characteristic trait of quantum mechanics, and pose essential issues and challenges to the interpretation of this pillar of m…
Universal quantum theory contains twisted logic
Francesco Atzori, Enrico Rebufello, Maria Violaris +9
Quantum theory is notoriously counterintuitive, and yet remains entirely self-consistent when applied universally. Here we uncover a new manifestation of its unusual consequences.…
