In QPSO, the strategy for handling the relation with neighbors is through Pbest and Gbest. But if you think in terms of Physics then in QPSO we need a field to interact with neighbor  which is I think no one had done.

Kindly have a look on the following article which may be helpful in this regard.

Research Particle Swarm Optimization: Algorithm and its Codes in MATLAB

I think in QPSO there is no such relation, it is only in PSO.
