Researchers demonstrated a novel method to generate and control one-way quantum steering between photon and magnon modes in a non-Hermitian cavity magnonic system by leveraging the cooperative effects of coherent and dissipative coupling, achieving robust quantum correlations that can be precisely controlled through the relative phase of cooperative dissipation and magnon mode frequency detuning.
The research proposes a novel scheme for generating scalable quantum entanglement using ultracold atoms in optical superlattices, where atoms are sequentially entangled in double wells and then reconfigured through lattice phase shifts, resulting in a noise-resistant genuine multipartite entangled state suitable for practical quantum computing implementations.
Scientists have discovered that in quantum systems, certain patterns of entanglement between parts of a system can reveal additional entanglement relationships not directly observed, proving this phenomenon exists for both small and large quantum systems and characterizing specific conditions under which it occurs.
