Abstract
The utilization of quantum states for the representation of information
and the advances in machine learning is considered as an efficient way of modeling
the working of complex systems. The states of mind or judgment outcomes are
highly complex phenomena that happen inside the human body. Decoding these
states is significant for improving the quality of technology and providing an
impetus to scientific research aimed at understanding the functioning of the human
mind. One of the key advantages of quantum wave-functions over conventional
classical models is the existence of configurable hidden variables, which provide
more data density due to its exponential state-space growth. These hidden
variables correspond to the amplitudes of each probable state of the system and
allow for the modeling of various intricate aspects of measurable and observable
physical quantities. This makes the quantum wave-functions powerful and
felicitous to model cognitive states of the human mind, as it inherits the ability to
efficiently couple the current context with past experiences temporally and
spatially to approach an appropriate future cognitive state. This paper implements
and compares some techniques like Variational Quantum Classifiers (VQC),
quantum annealing classifiers, and hybrid quantum-classical neural networks, to
harness the power of quantum computing for processing cognitive states of the
mind by making use of EEG data. It also introduces a novel pipeline by logically
combining some of the aforementioned techniques, to predict future cognitive
responses. The preliminary results of these approaches are presented and are very
encouraging with upto 61.53% validation accuracy.
