Change Log¶
All notable changes to this project will be documented in this file. This project adheres to Semantic Versioning.
[ next ] - [ TBD ]¶
Added¶
- interface (C++ and Python) to compile cQASM 1.0
Changed¶
- CC backend:
- renamed JSON field “signal_ref” to “ref_signal”
- renamed JSON field “ref_signals_type” to “signal_type”
- added option for new seq_bar semantics (cc firmware from 20191219 onwards)
- improved reporting on JSON semantic errors
- implemented option to output scheduled QASM files
Removed¶
Fixed¶
- changed register used for FOR loop, so it doesn’t clash with delay setting
