New type-I fusion gate achieves 75% success probability using only 4 ancillary single photons and passive linear optics—eliminating costly entangled Bell-pair ancillas. Reduces photon overhead for large entangled state generation by up to 2x.

MPLC-based free-space interferometers implement arbitrary M-mode unitary transforms requiring only O(M) phase planes—not O(M²)—experimentally validated on up to 16 spatial pixel modes including Hadamard, Bell-state measurement, and permutation unitaries.
