Measurement of Entanglement by Quantum Interferometry
Abstract
Measurement of quantum entanglement is one of the most important problems in quantum information science due to its direct applications to quantum communication, quantum teleportation, quantum metrology, and quantum computation. However, they remain highly challenging (e.g., resource intensive or methods are unknown) for high-dimensional or multi-particle entangled states. The objective of this research is to address this pressing demand by developing a conceptually new theoretical approach to the entanglement measurement problem. We aim to introduce a novel quantum interferometric method of measuring entanglement. The method will be tested with three types of quantum states- (i) two-qubit mixed states, (ii) two-particle infinite dimensional (continuous variable) states, and (iii) two-particle high-dimensional (discrete variable) states. The proposed method has two unique features- (i) it does not require a measurement on the entire quantum system, thereby reducing the amount of resource required for entanglement measurement, and (ii) it works even if detectors are not available for all the entangled particles. The research lies at the interface of two distinct fields- interferometry and quantum state measurements. It is expected to provide a deep understanding of how interferometry can be applied to entanglement measurement problems.
