Quantum computing makes use of qubits, the sub-atomic particles, which have the superfast processing power. It enhances optimisation.

A typical vaccine development takes a year and a half. Quantum computing can accelerate this process by solving complex equations with higher accuracy. Traditionally, physics-chemistry use a single equation — the Schrodinger equation. In classical computing, this equation is truncated or decoded in a simpler form. However, quantum computers simulate systems with greater precision by parameterising and solving the equation.

In vaccine development, one must have understanding of the protein structure of the virus or organism and its binding behaviour on the cells of the host. Here there are molecular simulations. This involves complex computing.
