Quantum state space dimension as a quantum resource
A. Plastino, G. Bellomo, A. R. Plastino · International Journal of Quantum Information · 2015
We argue that the dimensionality of the space of quantum systems’ states should be considered as a legitimate resource for quantum information tasks. The assertion is supported by the fact that quantum states with discord-like capacities can be obtained from classically-correlated states in spaces of dimension large enough. We illustrate things with some simple examples that justify our claim.
