XanaduAI/blackbird v0.3.0

Release 0.3.0

on GitHub

New features since last release

• Arrays and variables now support being defined as parameters (using braces) in a Blackbird template. (#34)

• Time-domain multiplexing programs are now supported, using the syntax type tdm (temporal_modes=3, copies=1). (#30)

• For-loops are supported inside Blackbird scripts. (#24)

  They can be defined using ranges via the syntax from:to:step:

  for float v in 2:10:3
    MZgate(v, v/2) | [0, 1]

  or lists

  for int m in [0, 2, 4]
    MeasureFock() | m

• Keyword arguments are supported inside operations; for example, MeasureHomodyne(select=[0, 1]) or MeasureFock(dark_counts=[1, 0.5, 3]). (#23)

• Indexing is supported inside both modes and arguments; for example, MZgate(list[2], list[0]) | [list[3], list[1]])). All indices allow expressions such as phases[-3 + 2*2]. (#23)

Bug fixes

• Templates are no longer changed when calling them and replacing the parameters with actual values. (#34)

Documentation

• TDM programs, for-loops and array indexing is added to the docs, along with other minor updates. (#28)
