SAND Report: Mid-circuit Measurement & Branching in QSCOUT: A Ping-Pong Teleportation Exemplar Program

Landahl, Andrew J.; Rudinger, Kenneth M.; Russo, Antonio R.; Ruzic, Brandon R.; Yale, Christopher G.; Clark, Susan M.

This document is intended to help users program the new mid-circuit measurement (MCM) and classical branching capabilities of the Quantum Scientific Computing Open User Testbed (QSCOUT). Here, we present and explain an exemplar “ping-pong teleportation” program that makes repeated MCM and branching calls. The program is written in Jaqal, the quantum assembly language used by QSCOUT. This document is intended to accompany a companion Jupyter notebook Exemplar_one_bit_teleportation_pingpong.ipynb.
