Vacuum squeezing is generated via residual 3WM in a SNAIL TWPA by choosing an operating flux point that favors 3WM over 4WM.
A tripartite quantum secret sharing protocol was experimentally realized in a superconducting microwave network, with reconstructed-state fidelities above the no-cloning threshold of 2/3.
Multiple parametric pumps in Josephson circuits reduce bipartite entanglement by redistributing two-mode squeezing across a larger network of modes and additional idler frequencies.
