Description
The detection and quantification of quantum entanglement poses significant challenges, especially as the size of quantum systems increases. Conventional methods such as quantum state tomography become impractical for large systems due to their exponential complexity. In this context, the SWAP test circuit, known for calculating the overlap between two quantum states, can be adapted as a tool for entanglement witnessing. The talk will present an integrated photonic circuit designed to implement the SWAP test algorithm and show how it can be used for entanglement detection. The circuit relies solely on linear optical components and operates at room temperature.
