Leveraging Secondary Storage to Simulate Deep 54-qubit Sycamore Circuits

2019 · arXiv (Cornell University)

In a recent paper, we showed that secondary storage can extend the range of quantum circuits that can be practically simulated with classical algorithms. Here we refine those techniques and apply them to the simulation …

Demonstration of quantum volume 64 on a superconducting quantum computing system

2020 · arXiv (Cornell University)

We improve the quality of quantum circuits on superconducting quantum computing systems, as measured by the quantum volume, with a combination of dynamical decoupling, compiler optimizations, shorter two-qubit gates, and excited state promoted readout. This …
