Can Quantum Computing Revolutionise AI-Designed Cancer Vaccines? A Scientist Explains
Artificial intelligence has started to revolutionize the field of modern medicine. It analyzes the tumour’s genome in just a few hours, predicts mutations that are more likely to cause an immune reaction, and helps to develop individual mRNA cancer vaccines much faster compared to standard laboratory procedures. Nevertheless, even with such impressive breakthroughs, artificial intelligence still lacks one essential thing – the complexity of biology.
The reality is that every tumour has thousands of mutations, millions of molecular interactions, and an evolving immune environment. Supercomputers are unable to model them all accurately. Quantum computing has become the solution for such limitations.
Using quantum computing in conjunction with artificial intelligence has become a very popular topic among scientists recently. Instead of replacing AI, quantum computers could significantly increase the processing capability of artificial intelligence, resulting in developing personalized cancer vaccines much faster. However, this is still a few years away from becoming a common procedure in clinics.
Why Cancer Vaccines Need Better Computing
While conventional vaccines are meant to stop individuals from being infected with a particular disease, cancer vaccines are developed based on an individual’s diagnosis. To start with, scientists need to sequence the patient’s tumour and discover specific mutations in the tumour cells, called neoantigens. Next, AI algorithms are used to examine these neoantigens and find out which of them would trigger the immune response of the patient.
Promising results have been shown in treating such types of cancer as melanoma, pancreatic cancer, glioblastoma, lung cancer, and kidney cancer. Numerous clinical trials with personalized mRNA vaccines show that proper targeting makes it possible to use immune response to destroy cancer cells. Over 130 studies presented during recent oncology conferences demonstrate the speed at which this area develops.
Targeting, however, turns out to be extremely difficult. Every single patient has a unique genetic makeup, so it means that the millions of different combinations of molecules must be checked until a certain number of them is chosen as vaccine targets.
This is becoming one of the biggest challenges of precision oncology.
Where Artificial Intelligence Already Excels
In fact, AI has already shortened the vaccine development process from years to weeks.
Current machine learning models analyze tumour DNA, RNA expression levels, protein interaction, immune cell behaviour, and past treatment outcomes all at once. Scientists no longer need to run laboratory experiments; they can predict using computation what mutations of the tumour will provide the strongest response of the T-cell.
There are several recent publications discussing how AI helps improve tumour immunity mapping for personalized mRNA vaccine development.
However, even state-of-the-art AI technologies require classical computers. The more genomic data, single-cell sequencing, and other multi-omics technologies produce data, the greater computational challenge becomes.
Why Quantum Computing Changes the Equation
Classical computers compute using bits that are either 0 or 1.
However, quantum computers operate using quantum bits, or qubits, which have the capacity of occupying more than one state at a time by the virtue of quantum superposition. This is possible in addition to quantum entanglement, where specific computations can take into account numerous possibilities at once.
Problems where there are many possibilities can be tackled using this kind of computing. Protein folding, molecular interactions, and immune system modelling are some examples.
The cancer field abounds in such optimisation problems.
More and more scientists think that quantum computing will assist artificial intelligence in evaluating molecular interactions, protein structures, binding of antigens, and potential drugs much more efficiently than current classical computers.
From Data Overload to Biological Insight
Cancer research in the modern age provides us with vast volumes of information.
Whole-genome sequencing, transcriptomics, proteomics, metabolomics, and spatial imaging produce billions of data points about an individual’s biological characteristics.
It is not anymore a problem of gathering data but of interpreting it.
Recent studies published in npj Digital Medicine suggest that one day quantum machine learning might assist in the integration of these enormous datasets of different omics, allowing researchers to classify tumors better, predict their treatment, and comprehend their evolution.
Rather than analyzing these data sets separately, advanced quantum computing may help discover certain biological relations which are beyond the capacity of conventional machine learning.
Designing Truly Personalised Cancer Vaccines
Longer term, the future of this technology is in providing truly personalized vaccines.
Consider the case of a patient who has been found to have melanoma. Within days of their diagnosis, their tumor genome is sequenced. The AI determines hundreds of potential neoantigens. Using quantum enhanced algorithms, simulations of the interaction between the neoantigen candidates and the patient’s immune system can be quickly run, ranking them based on predicted effectiveness.
The top candidates are then used to create an mRNA vaccine that has been tailored to that individual patient’s specific cancer.
It is not just science fiction. There are already early personalized mRNA vaccine programs that are using artificial intelligence extensively to identify negotiation.
Beyond Vaccines: Precision Oncology
However, the potential applications do not stop at vaccine design.
Quantum-powered AI might help diagnose cancer, discover new biomarkers, speed up drug discovery process, simulate protein interaction, and optimise combination of immunotherapies.
There is already an encouraging record on hybrid quantum-classical system used in computer-aided drug discovery for targeting epidermal growth factor receptor (EGFR), which is one of the most important treatment targets in oncology.
In a similar vein, there are efforts to utilise quantum computing in MRI-based tumour classification and single cell analysis, which are both crucial parts of precision oncology.
The Reality Check: We Are Not There Yet
Even with great optimism, however, quantum computing is still in its infancy.
Current quantum computers only have a small number of stable qubits, making them highly prone to errors in computations. Experts are in agreement that the present technologies do not yet have enough power to compete with classical supercomputers in routine biomedical applications.
Systematic reviews conducted recently have shown that there is a lack of evidence on quantum superiority in health care, especially for big machine-learning operations. Data loading difficulties, hardware limitations, and algorithm constraints continue to impede practical application.
Quantum computing, thus, shows promise but is not yet revolutionary.
The only practical way to go about it is through hybrid computing, where classical AI will do the bulk of the computations and quantum processors will handle specialized optimization tasks.
Why the Next Decade Matters
Despite the presence of numerous difficulties, the dynamics of development increases.
The combination of technologies such as AI, quantum computing, and molecular biology becomes more widespread every day, although only recently it was considered unreal. The research has proven the capability of the hybrid model of quantum-AI peptides for therapeutic uses in case of lack of biological data that could have application in creation of future vaccines.
Advances in personalized mRNA vaccines are developing separately but create conditions for the integration of improved computational methods as soon as quantum technologies become more mature.
Conclusion
Thus, the question regarding the use of AI in cancer vaccines design is irrelevant as it is already used.
A more interesting one concerns the possibility of using quantum computing for removal of computational barriers of personalized medicine.
At present, the answer to it is that potentially, but not right now.
It is unlikely that quantum computers will be able to substitute classical AI. On the contrary, they will become its strongest partner.
If the development of technologies proceeds in such a manner, then not only the cancer vaccines will be designed by artificial intelligence, but by an artificial intelligence enhanced with quantum computing.
And in such a way, a vaccine will be designed especially for every tumor biology.
