Abstract:

      We introduce some results of quantum information masking for arbitrary dimensional quantum states, including both deterministic and probabilistic masking machines. For qubit case, we prove that the maximal maskable set of states on the Bloch sphere with respect to any masker is the ones on a spherical circle on the Bloch sphere, proving the conjecture on maskable qubit states given in [Phys. Rev. Lett. 120, 230501 (2018)]. We provide explicitly operational unitary maskers for all maskable sets. The related recent researches on the relations among entanglement, coherence and particle-wave duality; as well as quantum uncertainty will be also introduced.
