    $IONQ is acquiring cybersecurity firm Elisity for ~$1.3B deal expanding beyond quantum computing into enterprise security. Elisity controls which devices can communicate across corporate networks giving IonQ an identity and security layer alongside its existing quantum networking capabilities. What makes this really interesting is IonQ could start generating security revenue long before quantum computers reach mass adoption while positioning itself for shift toward post quantum security.
