Qiskit/qiskit
Jun 2020 - Jun 2021
Qiskit is an open-source SDK for working with quantum computers at the level of extended quantum circuits, operators, and primitives.
Role in this project:Back-end Developer
Back-end DeveloperContributions:55 reviews, 12 commits, 12 PRs in 1 year
Contributions summary:Zachary's primary contribution focused on implementing features related to the "rep_delay" functionality within the Qiskit framework, specifically impacting the `assemble` module. This included adding flags, integrating dynamic rep rates, and modifying backend configurations. The user also addressed critical issues by casting `rep_time` back to int, updating schemas, and enabling zero rep delays. Further contributions involve managing and fixing issues with parametric pulses and the handling of low-frequency settings for circuits.
