N\'eel ordered antiferromagnets exhibit two-mode squeezing such that their ground state is a nonclassical superposition of magnon Fock states. Here we theoretically demonstrate that antiferromagnets can couple to spin qubits via direct…
A novel type of correlation involving particle-antiparticle pairs was found out in the 1990's. Currently known as Squeezed or Back-to-Back Correlations (BBC), they should be present if the hadronic masses are modified in the hot and dense…
