Setup Of Nine-Qubit Linear Optical Platform

Caption

This is the experimental setup. Ultraviolet laser pulses with a central wave-length of 394 nm, pulse duration of 150 fs, and repetition rate of 80 MHz pass through three HWP-sandwiched BBO crystals and a single BBO to produce three entangled photon pairs (in spatial modes 1-3, 5-6, and 7-9) and a pair of photons (in spatial 4-8), respectively. All of these photons are put into a linear optical net- work to prepare the ground state. The steps of ground state preparation, anyon creation, anyon braiding, anyon annihilation, and measurement are marked. (C-BBO, sandwich-like BBO + HWP + BBO combination; S-BBO, single BBO; QWP, quarter-wave plate; HWP, half-wave plate; PBS, polarizing beam splitter; D-PBS, double PBS; D-BS, double beam splitter.)
