In a new publication, scientists at start-up QSimulate describe the application of a new and novel implementation of quantum mechanics (QM) to the question of how well various diverse drugs bind to SARS-CoV-2 Mpro, a protein required for the replication of COVID-19. The diversity in structure and formal charge of this set is large, rendering accurate scoring by traditional methods difficult or impossible. However, QSimulate has demonstrated that QM with high accuracy can successfully rank binding strength for this challenging set. The results suggest a broader path forward for the integration of QM in drug discovery.

AWS made an announcement on the general availability of Amazon Braket, in which QSimulate's collaboration with Amgen was highlighted as a success of QSimulate as a launch partner of Amazon Quantum Solutions Lab.

...Yax Sun, Director and Narbe Mardirossian, Scientist, at Amgen. “By collaborating with the Amazon Quantum Solutions Lab and QSimulate, we’ve been able to quickly build and test a cloud-based approach using multiple compute resources on AWS for a critical drug discovery process—a process we plan to transition to a quantum computer in the future when it is practical. Looking ahead, Amazon Braket has the potential to substantially benefit the research and scientific community by providing on-demand access to quantum computing technologies and accelerate innovation in biotechnology.

The QSimulate quantum simulation platform that enables unprecedented high throughput, QSimulate-MI, has been enlisted by JSR Corporation, one of the major players in the display, semiconductor, optical, and polymer materials market, to enable the discovery of novel materials using Materials Informatics (MI) approaches. In this partnership, QSimulate has provided JSR access to its unique automated QM tools on the cloud, making it possible to run high accuracy quantum calculations for thousands of molecules on a daily basis. This, in turn, provides a superior dataset for Materials Informatics, as well as the ability to efficiently supplant that training set as required.

Quantum-based startup QSimulate has announced a collaboration with Amgen focused on integrating large scale, high accuracy, quantum mechanics calculations (QM) into the drug discovery pipeline. The impetus for the new collaboration is the development by QSimulate of a novel implementation of density functional theory, a variant of QM, that allows these calculations to be run with discovery-relevant throughput on realistic ligand/protein models for the first time by taking full advantage of cloud resources.

QSimulate has been selected among the few launching partners of Amazon Quantum Solution Lab as a pioneer in the quantum mechanical simulations space.
The Amazon Quantum Solutions Lab connects customers with quantum computing experts from Amazon and its technology and consulting partners to help discover new applications and find ways to apply quantum computing inside their organizations. As the technology eventually reaches the point of commercial viability, AWS and its partners will collaborate on experiments with customers and guide them to incorporate quantum solutions into their business. Among other launching partners are 1Qbit, Rahko, Rigetti, QCWare, Xanadu, and Zapata.
