A long-waited release...

Added

  • CC backend:
    • support for cQASM 1.2 features through new IR
      • limitations
        • integer values must be non-negative
    • support for resource constrained scheduler
    • creates .map file reporting measurement statements present in input, to allow retrieving measurements downstream
  • support for Python up to 3.11

Changed

  • pass dec.Instructions: duration=0 in new-style decomposition rules now disables checking whether expansion fits, allowing automatic calculation of duration (and requiring scheduling after decomposition of such rules)
  • CC backend:
    • now uses new IR
    • no longer requires key "cc" to be present in instructions that define gate decompositions
    • key "readout_mode" no longer used
      • classification of gates as measurement - which is used for the resource constrained scheduler, and to output a map of measurements - now based on signal definition ("signal/type" equals "measure" and "signal/value" non-empty)
      • classification of gates as real-time measurement now based on signal definition ("signal/type" equals "measure" and "signal/value" empty)
    • absence of key "cc" now implies empty "signal", so "cc": { "signal": [] } is no longer necessary
  • passes and architectures self-register statically to their respective factories
  • initial placer uses new IR and new MIP solver called HiGHS

Removed

  • CC backend:
    • support for JSON key "pragma/break" for instruction definitions
    • macro expansion for JSON key instruction/signal/value (unused anyway)
  • support for sweep points in API and the WriteSweepPointsPass
  • support for Python up to and including 3.6

Fixed

  • pass dec.Instructions
    • corrected ordering of instruction decomposition (which reversed multi-statement decompositions)
    • decomposed instructions were silently made unconditional, we now copy instruction condition to decomposed instructions
