  We present an experimental implementation of a two-qubit photonic quantum
processor fabricated using femtosecond laser writing technology. We employ
femtosecond laser writing to create a low-loss reconfigurable photonic chip
implementing precise single-qubit and two-qubit operations. The performance of
single-qubit and two-qubit gates is characterized by full process tomography.
An exemplary application of the processor to determining the ground state
energy of an H2 molecule using the variational quantum eigensolver algorithm is
demonstrated. Our results highlight the potential of femtosecond laser writing
technology to deliver high quality small-scale quantum photonic processors.
