Quantum computing promises to efficiently tackle a set of important but classically intractable tasks. The prospects are especially exciting as experimental qubit hardware continues to scale rapidly. However, fault-tolerant quantum computation remains well out of reach for the foreseeable future. Therefore noisy quantum computations are being integrated into classical-quantum computational workflows. In this talk I will discuss (1) the complexity of hybrid workflows from the perspective of quantum many-body simulation, (2) the development and validation of hybrid algorithms using the tensor network quantum virtual machine developed at ORNL, and (3) the unique opportunity for large-scale high-performance computing systems to perform the ultimate classical verification of near-term quantum computations and their role in guiding future hybrid classical-quantum algorithms.
