Adaptive Procedures for Discrimination Between Arbitrary Tensor-Product\n Quantum States

2019 · arXiv (Cornell University)

Discrimination between quantum states is a fundamental task in quantum\ninformation theory. Given two arbitrary tensor-product quantum states (TPQS)\n$\\rho_{\\pm} = \\rho_{\\pm}^{(1)} \\otimes \\cdots \\otimes \\rho_{\\pm}^{(N)}$,\ndetermining the joint $N$-system measurement to optimally distinguish between\nthe two states is …
