Device challenges for near term superconducting quantum processors: frequency collisions

2018

The outstanding progress in experimental quantum computing with superconducting Josephson-junction based qubits over the past few decades has pushed coherence times many orders of magnitude above that of the first measured. We are also in …

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 …
