Query: A chiral route to spontaneous entanglement generation   We study the generation of spontaneous entanglement between two qubits
chirally coupled to a waveguide. The maximum achievable concurrence is
demonstrated to increase by a factor of $4/e \sim 1.5$ as compared to the
non-chiral coupling situation. The proposed entanglement scheme is shown to be
robust against variation of the qubit properties such as detuning and
separation, which are critical in the non-chiral case. This result relaxes the
restrictive requirements of the non-chiral situation, paving the way towards a
realistic implementation. Our results demonstrate the potential of chiral
waveguides for quantum entanglement protocols.
