Batch Entanglement Detection in Parameterized Qubit States using Classical Bandit Algorithms

ArXi:2406.19738v2 Announce Type: replace-cross Entanglement is a key property of quantum states that acts as a resource for a wide range of tasks in quantum computing. Entanglement detection is a key conceptual and practical challenge. Without adaptive or joint measurements, entanglement detection is constrained by no-go theorems (Lu [Phys. Re. Lett., 116, 230501 ]), necessitating full state tomography. Batch entanglement detection refers to the problem of identifying all entangled states from amongst a set of $K$ unknown states, which finds applications in quantum information processing.
