A new case study explores how IBM Quantum® and Moderna recently demonstrated the use of quantum simulation to predict the secondary protein structure of a 60 nucleotide-long mRNA sequence, the longest nucleotide folding pattern ever simulated on a quantum computer. Understanding how proteins fold from a given nucleotide sequence is crucial for creating effective mRNA vaccines. Using 80 qubits of an IBM Quantum Heron chip, the team employed CVaR-based VQA—a quantum optimization algorithm modeled after financial risk assessment techniques—to achieve the largest demonstration of this algorithm’s utility to date.
This study is a powerful example of the progress the quantum community is making toward quantum advantage — the point at which quantum computers are shown to be more efficient, more accurate, or cheaper than classical computers for a particular task. As we explore different applications, one use-case at a time, IBM Quantum partners and clients are taking essential steps in our journey of bringing useful quantum computing to the world.
