NuQasm2 v0.33 -- Bug fix and new interface

NuQasm2 v0.33

• Add nuqasm2.load_string() function for proposed Qiskit interface
• Fix issue #1 "Ops which cannot be unrolled are silently ignored"
• Fix issue #2 "Parameters of custom gates not recognized"

NuQasm2 v0.32 -- Regression testing and exceptions

NuQasm2 v0.32

• Regression test suite started
• Handle Ast2CircException
• Raises Ast2CircOpNotFoundException if operation not appended to circuit
• Now Makefile won't make test if variable not defined, message instead

NuQasm2 v0.31 -- features and bug fixes

NuQasm2 v0.31

• -q flag with -c outputs OPENQASM 2.0 source after unrolling custom gates
• clean up example because nuqasm2 doesn't handle measure q -> c
• fixed bug in file output
• param binding now will pass unbound param text if no param can be bound in unrolling op in gate definition
• created regression test examples
• fixed bug error no space after gate reg list before curly

NuQasm2 now generates Qiskit QuantumCircuit objects

• Install via setup.py
• Command nuqasm2 be used to demo AST generation and/or circuit generation from OPENQASM 2.0 source.
• Unrolls custom gate definitions from OPENQASM 2.0 .inc files
• Doesn't really handle transcendental parameters to gate definitions other that pi.
• Companion project qis_job now optionally uses nuqasm2 code to assemble OPENQASM 2.O instead of using the Qiskit qasm parser.

Proof of Concept

Now supports end-of-line comments.

nuqasm2 v0.22

• bug fixes having to do with spaces and register names
  • measure
  • barrier
• test examples added from Qiskit Terra examples to test suite
  • entangled_registers.qasm
  • plaquette_check.qasm

nuqasm2 v0.21

• added include path regimen
• better reporting of file paths
• improved exceptions

New Output Format

Now supports include syntax.

This necessitated changing the output format. The README.md documents this fairly well.

There is no notion of "include path" yet so if a file does include "qelib1.inc" that file will need to be in the current directory for now.

Proof of Concept

• More control over profiling
• Improved regression testing

Proof of Concept

Now copes with extraneous spaces in qasm input.
