Quantum information processing necessitates the coherent synchronization of photons generated by probabilistic quantum sources. This synchronization can be achieved through the utilization of advanced quantum memories. Photon sources and quantum memories leveraging room temperature technology are rapidly emerging as leading candidates for the next generation of quantum technology. Our work demonstrates a room temperature probabilistic entangling CNOT gate using synchronized photons pairs. The performance of the gate is investigated with single photon pairs synchronized using quantum memory in contrast to the gate performance with accidental photon pairs from the single photon source only. Photon synchronization results in an enhancement of photon pair coincidence rate and hence improves the performance of the gate. Entanglement fidelity is well above the threshold of 0.78 and violates Bell inequalities. Our research advances the frontier of scalable photonic quantum technologies, contributing to their development and implementation.
