Quantum entanglement is an important and often necessary resource for quantum information processing e.g. the measurement-based quantum computer [1]. Current protocols for generating entanglement between emitters assume near identical spectral properties [2–3], which is a major obstacle for using integrated solid-state emitters in photonic structures as a scalable platform. The solid-state emitters can vary significantly from one another in terms of both lifetimes and central energies due to…
