Squeezed vacuum states from a whispering gallery mode resonator
Alexander Otterpohl, Florian Sedlmeir, Ulrich Vogl +9
Squeezed vacuum states enable optical measurements below the quantum limit and hence are a valuable resource for applications in quantum metrology and also quantum communication. H…
