Methods and apparatus for generating quantum entanglement detect success of entanglement attempts by monitoring output signals from one or more detectors for heralding patterns indicating that a pair of quantum systems is in an entangled quantum state. In response to detecting a heralding pattern that indicates a successful entanglement attempt a low latency signal is output on one or more signal lines; and a higher latency message is transmitted by a messaging interface. The higher latency message contains information that identifies the pair of quantum systems entangled by the successful entanglement attempt. The pair of quantum systems may be inhibited from participating in further entanglement attempts while further entanglement attempts are performed on other pairs of quantum systems.
