"built four qubit module... preparing the two qubits in an entangled state of single excitation called a Bell state to ensure emitted photon travels in correct direction... achieved more than 96% fidelity—this means if intended to emit photon to the right, 96% of the time it went to the right... connect multiple modules and emit and absorb photons... modular architecture that combines many smaller-scale processors into one larger-scale, and more powerful, quantum processor"
