Abstract
Photonic controlled-phase gates that include a dipole emitter chirally coupled to a plurality of photonic qubit pairs in a waveguide are disclosed herein. Each photonic qubit pair includes a two-qubit state |xy, wherein the two-qubit state |xycomprises a combination of single-qubit states |0and |1, and may be |00, |01, |10, and |11. The dipole emitter is configured to interact with the single-qubit state |0to impose a π phase shift, and the dipole emitter interacts with states |00, |01, and |10to impose the π phase shift.
