Dear Editor,

It is with great interest that we read the article by Tay et al. on face recognition with quantum associative networks, which was recently published in Cognitive Computation [1]. In a series of computer simulations, the authors demonstrated how non-Turing-based quantum computing can be harnessed for viewpoint-invariant face recognition using Hebb-like storage of image-encoding Gabor wavelets implemented in a quantum-holographic procedure. The presented model was largely motivated by Hopfield’s neural network [2], which was then transformed into a quantum-holographic process in which the Hebbian memory was replaced by multiple self-interferences of quantum plane waves [3].

This transformation was achieved by means of a simple substitution (see Table  1for details) of Hopfield’s real-valued variables by the complex-valued variables changing as sinusoids (waves), while simultaneously preserving all input-to-output transformations in the model. By doing this, it becomes...
