We propose to deploy concepts from Quantum Mechanics to simulate behaviors exhibited by groups of human subjects. The results generated by the model are binary-type decisions (yes/no choices). The choices are rendered by the subjects being simulated. The decisions are about an item to which all subjects are exposed in a known setting or context. The item is a classical object that each subject is known to care about in their own, special way. These individualistic ways of caring or valuing the item are represented by quantum operators (Hermitian matrices). Further, each subject’s state of mind about the item is assigned to a quantum state. Quantum operators act on such quantum states to yield eigenvalues. The eigenvalues are the manifested “yes” or “no” decisions by subjects that make a choice about the item during the time period under simulation.

Our mapping extends to inter-subject dynamics. Spin statistics are associated with quantum states of inter- acting subjects. Establishment of consensus in pairs of subjects deciding jointly about the item is simulated by entangled states. The four distinct corner cases or ways in which the subjects can become entangled are addressed. In particular, entanglement between subjects that cannot reach positive consensus (agreement) and results in a stand-off state is mapped to the famous singlet also known as the EPR state. The overall dynamics of entangled states are modeled so as to ensure conformity with standard quantum rules for bipar- tite states under unitary evolution.
