Release 0.1.1

New features since last release

• A constants block has been added to support declaring script-level constants which can be used as parameters in statements. (#7)

  constants:
     p0: [3.141592653589793, 4.71238898038469, 0];
     p1: [1, 0.5, 3.141592653589793];
     p2: [0, 0, 0];
  end;
  
  Sgate(0.123, 4.5) | [2];
  BSgate(p0, 0.0) | [1, 2];
  Rgate(p1) | [2];
  MeasureHomodyne(phi: p0) | [0];
  

Improvements

• The maximum wire value used in a statement within a definition will be the number of wires declared. For example, if a single statement within a definition is applied to wire 4, then the declared wires will be 0, 1, 2, 3, and 4. (#2)

• xir.Validator now also checks that parameters used in definitions are not declared constants. (#7)

• The XIR package is now automatically uploaded to PyPI when a new release is published on GitHub. (#9)

Bug Fixes

• Wires are implicitly added to an observable if they are not explicitly declared. (#2)

• Validation now checks that applied wires is a subset of declared wires. (#2)

• decimal.Decimal and DecimalComplex objects in nested lists and dictionaries are correctly converted to float and complex respectively when extracted. (#7)

Documentation

• The out declaration in the Grammar overview is now valid XIR syntax. (#8)
