    "abstract": "Using a linear optical elements and post-selection, we construct an entangled\npolarization state of three photons in the same spatial mode. This state is\nanalogous to a ``photon-number path entangled state\u0027\u0027 and can be used for\nsuper-resolving interferometry. Measuring a birefringent phase shift, we\ndemonstrate two- and three-fold improvements in phase resolution.",
