A $5 million grant from the U.S. National Science Foundation is funding the creation of TangleLab, a new national testbed for hybrid quantum-classical computing led by the Pittsburgh Supercomputing Center. Rigetti Computing and Hewlett Packard Enterprise are partnering in the project, which will give researchers and students hands-on access to an integrated system designed to explore the future of scientific computing. “Carnegie Mellon has long been a leader in advances in computing, and through the Pittsburgh Supercomputing Center we continue to invest in the infrastructure that enables the next generation of discovery,” said Theresa Mayer, vice president for research. TangleLab aims to define how quantum and classical computers will work together, while also preparing a workforce equipped to utilize these emerging technologies. TangleLab: Integrating Quantum Technologies with High-Performance Computing A $5 million grant from the U.S. National Science Foundation is establishing TangleLab, a national testbed designed to explore the integration of quantum computing with existing high-performance computing infrastructure. This investment signals a clear federal commitment to hybrid quantum-classical systems. Led by the Pittsburgh Supercomputing Center, TangleLab will not deploy a standalone quantum computer, but instead focus on creating an open platform for researchers and educators to investigate how quantum processors can function as specialized resources within broader computing environments. This approach acknowledges that quantum computers are not intended to replace classical systems entirely, but rather to augment them for specific, computationally intensive tasks. The platform, developed in partnership with Hewlett Packard Enterprise and Rigetti Computing, aims to address fundamental questions about the design, programming, management, and optimization of these hybrid systems. “With TangleLab, we are really looking into integrating quantum technologies into classical high-performance computing environments to enable hybrid quantum-classical workflows that can demonstrate potential quantum utility,” said Bruno Abreu, deputy scientific director at PSC.
