The work done in this paper is an extension of the work done by Mpofu et al in [1]. The motivation for this paper is to show the potential of quantum bio-sensing techniques in applications to complex viruses like the human immunodeficiency virus (HIV) and to show it's potential in binding reactions where the signal is small and can potentially be buried in noise. In this paper we show theoretically that using quantum states of light such as the Fock state improves the precision in the estimation of kinetic parameters measured from the sensorgrams produced by the Kretschmann conguration. Though the Fock state is not the only quantum state in this study we look only at the Fock state because it has been shown to be the state which offers the best enhancement [1]. We show here that the Fock state allows us to measure the parameters more accurately in comparison to the classical (Coherent) state of light. We consider in this paper a binding reaction involving HIV type 1 (HIV-1). Specifically we look at the binding reaction between a variant of HIV-1 protease and nelnavir which is an inhibitor. Such a study is also offers value for drug discovery research as it points to the development of new technologies which can be applied to testing the efficacy of new drugs. Quantum technologies can prove to be useful in the fight against the HIV pandemic and assist in the continual research towards the development of treatments and a cure.
