Reliable Entanglement Verification

Understand

Any experiment attempting to verify the presence of entanglement in a physical system can only generate a finite amount of data.

• The statement that entanglement was present in the system can thus never be issued with certainty, requiring instead a statistical analysis of the data.
• Because entanglement plays a central role in the performance of quantum devices, it is crucial to make statistical claims in entanglement verification experiments that are reliable and have a clear interpretation.
• In this work, we apply recent results by M.
