  In the cited paper [White, T., Mutus, J., Dressel, J. et al., "Preserving
entanglement during weak measurement demonstrated with a violation of the
Bell-Leggett-Garg inequality", npj Quantum Information 2, 15022 (2016),
arXiv:1504.02707], experimental results were presented that clearly prove that
the quantum entanglement between two qubits is preserved after weak enough
measurements are performed on them. The theoretical interpretation of the
reported results, however, requires further consideration. The remarks made in
this paper may have serious implications both for quantum foundations and for
quantum cryptography.
