A Probabilistic Graphical Model-based Approach for Minimizing Energy Under Performance Constraints

2015 · ACM SIGARCH Computer Architecture News

In many deployments, computer systems are underutilized -- meaning that applications have performance requirements that demand less than full system capacity. Ideally, we would take advantage of this under-utilization by allocating system resources so that …

Navigating the dynamic noise landscape of variational quantum algorithms with QISMET

2022 · arXiv (Cornell University)

Transient errors from the dynamic NISQ noise landscape are challenging to comprehend and are especially detrimental to classes of applications that are iterative and/or long-running, and therefore their timely mitigation is important for quantum advantage …

CAFQA: A Classical Simulation Bootstrap for Variational Quantum Algorithms

2022

Classical computing plays a critical role in the advancement of quantum frontiers in the NISQ era. In this spirit, this work uses classical simulation to bootstrap Variational Quantum Algorithms (VQAs). VQAs rely upon the iterative …
