New Quantum Chemistry Engine Speeds Up Drug Discovery & Materials Science

A new technology called the Extreme-scale Electronic Structure System (EXESS) is now available to scientists, offering a significant leap forward in tackling complex chemical problems. Developed by QDX, the system promises to accelerate research across fields like drug discovery and materials science.

Unlocking the Potential of Quantum Chemistry

Quantum chemistry calculations are essential for developing new medicines and materials. Researchers use these simulations to understand how drugs interact with the body at a molecular level, allowing them to refine drug design for optimal effectiveness. However, these calculations traditionally require immense computing power.

According to Loong Wang, CEO of QDX, modelling quantum chemistry has historically been so computationally intensive that it could take longer to simulate a compound than to physically synthesize and test it. The challenge stems from the exponential increase in computing needs as the number of atoms in a system grows – particularly when dealing with large molecules like proteins containing thousands of atoms.

Did You Know? EXESS can perform more than 1 quintillion calculations per second to address questions in quantum chemistry.

EXESS aims to overcome these limitations by making quantum chemistry calculations fast enough for practical application. QDX states that the system operates 3,000 to 4,000 times faster than many existing quantum chemistry software packages. This speed is achieved not through revolutionary hardware like quantum computing, but through extensive optimization of the software’s individual components.

How EXESS Achieves its Speed

The team at QDX found ways to run multiple operations simultaneously, a departure from the sequential nature of many quantum chemistry algorithms. Wang likened this to optimizing a kitchen for efficiency, enabling a faster “throughput” of calculations. One specific technique employed is molecular fragmentation, which breaks down complex problems into smaller, manageable pieces that can be computed concurrently and then reassembled.

Expert Insight: By dramatically reducing calculation times, EXESS has the potential to shift the bottleneck in materials science and drug discovery from computational limitations to the speed of experimental validation. This could lead to a more rapid cycle of innovation.

The impact of this speed increase is significant. Wang explained that calculations that previously took a month can now be completed in approximately 12 minutes using EXESS.

QDX is initially focusing on applying EXESS to drug discovery, specifically optimizing drug-body interactions and understanding drug resistance. However, the company is offering free access to the system for approved research projects, and a limited version is also available to the public.

Wang expressed hope that researchers will explore applications beyond QDX’s current focus, stating, “We really want to see is people focus on the other 99% of problems that exist, and see what they do with it, and see whether in some of those areas, we might be surprised at how quantum chemistry can help make a difference.”
