Certification of complex devices is an important requirement for their application, especially in security-related scenarios. One of the strongest ways to test components is the so-called "device-independent" one, where no knowledge about or trust in their internal workings is required. Self-testing is a method for device-independent certification of entanglement using the result of a Bell test.
