  Quantum interference can be enabled by projecting the quantum state onto ambiguous properties that render the photons indistinguishable. By combining these ideas, here we design and experimentally demonstrate a simple and robust scheme that tailors quantum interference to engineer photonic states. We believe these spatially-engineered multi-photon quantum states may be of significance in fields such as quantum metrology, microscopy, and communications.
