Multimode photon blockade paper published in Nature Physics

Our paper on multimode photon blockade with Kevin He, David Schuster, Liang Jiang, Wenlong Ma, and other members of the Schuster group is out in Nature Physics!  We use photon blockade to implement higher-order interactions between photons stored in modes of a multimode cavity. 

In a single mode, we use the blockade to engineer a qutrit and create the basis Fock states using optimal control pulses acting only on the cavity mode.
With the blockade on, we create W-states of up to 5 modes with only uniform drives on all the cavity modes. We also implement a scheme for multimode Wigner tomography that does not require perfect joint parity measurements.
