  The application of blockchain technology can be beneficial in the field of
healthcare as well as in the fight against the COVID-19 epidemic. In this work,
the importance of blockchain is analyzed and it is observed that blockchain
technology and the processes associated with it will be utilised in the
healthcare systems of the future for data acquisition from sensors, automatic
patient monitoring, and secure data storage. This technology substantially
simplifies the process of carrying out operations because it can store a
substantial quantity of data in a dispersed and secure manner, as well as
enable access whenever and wherever it is required to do so. With the
assistance of quantum blockchain, the benefits of quantum computing, such as
the capability to acquire thermal imaging based on quantum computing and the
speed with which patients may be located and monitored, can all be exploited to
their full potential. Quantum blockchain is another tool that can be utilised
to maintain the confidentiality, authenticity, and accessibility of data
records. The processing of medical records could potentially benefit from
greater speed and privacy if it combines quantum computing and blockchain
technology. The authors of this paper investigate the possible benefits and
applications of blockchain and quantum technologies in the field of medicine,
pharmacy and healthcare systems. In this context, this work explored and
compared quantum technologies and blockchain-based technologies in conjunction
with other cutting-edge information and communications technologies such as
ratification intelligence, machine learning, drones, and so on.
