A resource-efficient and noise-robust entanglement witness based on the swap test
Sebastiano Guaraldo, Sonia Mazzucchi, Alessio Baldazzi +2
Quantum entanglement is an essential resource for quantum technologies, and the controlled swap test provides a versatile tool for its detection and quantification. Here, we propos…
