Abstract
The need for IR4 technologies with faster and accurate results for huge health datasets is required. Healthcare has made a lot of advancements with technologies and has certain issues in terms of carbon emission. This in turn sets the patient's life in risk. The study proposes a model for all the healthcare sectors. The study deals with the various quantum neural networks implemented on diabetes retinopathy and COVID-19 images. The quantum computing model outperformed all other machine learning and deep learning models giving more accurate results in less time. The revolution of quantum computing has proven the healthcare in diabetes retinopathy and COVID-19 detection to be faster. It can henceforth be implemented for early warning of the diseases and provide treatment for the patients.

A Review on Applications of Quantum Computing in Machine Learning
Quantum computing is an area of computing focused on developing computer technology based on the principles of quantum theory (which explains the behavior of energy and material on the atomic and subatomic levels). Computers used today can only encode information in bits that take the value of 1 or 0—restricting their ability. Quantum computing, on the other hand, uses quantum bits or qubits. It harnesses the unique ability of subatomic particles that allows them to exist in more than one state (i.e., a 1 and a 0 at the same time).

A Taxonomy of Quantum Computing Algorithms: Advancements and Anticipations
A quantum computing system is a computer technology based on quantum theory (which explains how energy and matter behave at atomic and subatomic levels). Modern computers can only encode information in bits that have a value of 1 or 0, which limits their capabilities. Qubits, on the other hand, are an essential part of quantum computing. It takes advantage of the unique property of subatomic particles, which allows them to exist in more than one state at once (i.e., as a 1 and a 0).
