Update pyzx requirement from <0.6.5,>=0.6.4 to >=0.6.4,<0.7.1

[dependabot[bot]]

Updates the requirements on pyzx to permit the latest version.

Release notes

Sourced from pyzx's releases.

v0.7.0

[0.7.0] - 2022-02-19

This release adds several new features: support for evaluating ZX-diagrams as tensor networks using the hypergraph contraction methods of quimb, basic support for interacting with the Rust port of PyZX quizx, support for 'hybrid' ZX-diagrams that contain classical wires and measurements, as well as several heuristics for trying to optimise the CNOT count of a circuit that is to be extracted from a ZX-diagram.

There is one small breaking change, which is that Graph.inputs and Graph.outputs are now methods that return a list, instead of being lists themselves.

Added

• Added support for evaluating ZX-diagrams as tensor networks in quimb (courtesy of Paul Tirlisan).
• Added quizx backend for the Graph class.
• Graph vertices can now carry a ground generator. This makes it possible to represent measurements and classical control in the diagrams. See the accompanying paper (courtesy of ABorgna).
• Added extract.lookahead_extract that uses heuristics to extract circuit with less CNOT gates (courtesy of VladMoldoveanu).
• Added local_search submodule for doing simulated annealing on rewrites of a ZX-diagram to try to get it to be extracted with less CNOTS (courtesy of Ryan Krueger).
• Added new rewrite rule for ZH-diagrams hsimplify.par_hbox_intro_simp() that can remove some H-boxes.
• Added several new rewrite rules to basicrules and mbqc.
• QASM parser: added support for controlled-Hadamard and controlled-Z phase gates.
• QC parser: added support for SWAP gates (courtesy of wdomitrz).
• Added Graph.set_inputs() and Graph.set_outputs() to set a list of vertices to be the inputs/outputs of a diagram.
• Added Graph.num_inputs() and Graph.num_outputs() to get the number of inputs and outputs of a diagram.

Changed

• Graph.inputs is now a method that returns a list of inputs, instead of Graph.inputs being a list itself. The same for Graph.outputs.

Fixed

• Several incorrect scalars were fixed in ZH-diagram rewrite rules.

[0.6.4] - 2021-01-27

The main feature added is support for copying and pasting inside the editor. This release should also hopefully fix the issue where users of the PyPI version can't use zx.draw and the editor.

Added

• Added functionality to copy and paste parts of a diagram in the editor.
• qasm files can now include u1/u2/u3 gates.
• Method BaseGraph.merge() to merge two graphs in place.
• Method BaseGraph.subgraph_from_vertices() to get the induced subgraph from a set of vertices.

Changed

• tikz_to_graph() is now a bit more versatile in what it accepts as valid phases.
• matrix_to_latex() is slightly more intelligent about parsing numbers.
• Changed colours in editor to match those of zx.draw.

Fixed

• Decomposing a Hadamard into Euler angles gave wrong scalar.
• Added d3.v5.min.js to the manifest, which hopefully prevents the issue where people using the PyPI version can't see graphs drawn with d3.

[0.6.3] - 2020-12-2

Added

• Added settings.drawing_auto_hbox to toggle the default value of auto_hbox when using zx.draw().

@gwwatkin does this help with what you were trying to do?

QASM parser: added support for controlled-Hadamard and controlled-Z phase gates.

https://github.com/Quantomatic/pyzx/commit/73998cb6eafda13832306edf2dd4d8ec6fe236cd

[alexnguyenn]

Also realized it was the issue you commented on as well: https://github.com/Quantomatic/pyzx/issues/48

[gwwatkin]

Yes it would make the parsing via PyZX more robust, as it would allow us to parse small QFTs with it. It's cool that they have it now.

Unfortunately we still can't use it for larger ones (>48 qubits I think) because PyZX runs into precision problems with very small angles.

Makes me think though we should offer the user the possibility of choosing their parser.

[gwwatkin]

I also see that they are adopting a different convention from ours
