The development and wide-scale use of Quantum Computing will give a great boost to the field of healthcare and medicine and particularly digital healthcare. Quantum computing, as well as novel and radically different algorithmic search and data homogenization techniques, may provide unparalleled processing power and speed. In reality, these innovations have already begun to significantly change various aspects of healthcare and medicine.

Research has also shown that quantum computing can improve cancer treatment procedures for radiation therapy, which could lead to a breakthrough in cancer care and cancer management by reducing the adverse side effects of radiation treatment.

The power of quantum computers is also leveraged to process enormous health records that are realistically stored in Large Data systems or in a Data Lake, and sophisticated quantum encryption is also applied to PHIs, Secure Health Information so that such highly sensitive data can not be tempered by anyone. Quantum computers will also largely tackle the complexities of developing a robust digital healthcare environment that involves collaborating with and correlating with a range of data sources, such as medical records, clinical data, medical imaging data, medical prescriptions, etc. This enormous amount of multipurpose data from different data sources, creating connections and inferences, can be processed by Quantum computers to bring a comprehensive view of a particular medical case at large. 

Machines with Quantum Magnetic Resonance Imaging (Q-MRI) can produce extremely detailed images that allow individual molecules to be visualized. By providing incredibly precise measurements and enabling doctors to look far deeper into small particles that traditional computing technology would not be able to detect, quantum computing technology will enhance MRI technology. It is possible to view diagnostic images in their very minute details with the use of quantum computing along with artificial intelligence.

In order to take advantage of quantum, the healthcare industry will still need to develop a new range of applications, and it will still not account for the hardware costs and the running costs to cool the devices and keep them working. These capabilities could not help keep cost pressures low if healthcare costs were not already high enough, and because quantum poses all sorts of possible security threats, data privacy may be further compromised for healthcare patients.
