v2.0.0

This update adds support for a wider range of physical states and operations.

What's Changed

• Added the Pauli String and Pauli Time Evolution gates to the circuit-builder and circuit! macro.
• Added the equals_without_phase method to state to check phase-independent equality.
• Added a method to normalise states.
• Added Display trait implementations on all operators.
• Added the deep_clone method to parameter.
• Added new constructors for Hartree-Fock, GHZ, and Bell states.
• Added a method to apply the normalised version of a Pauli String.
• Added methods to calculate the Fubini-Study distance and fidelity metrics to state.
• Increased test coverage for Pauli Strings.
• Added a method to get the length of Pauli Strings.
• Added a method to convert Pauli operators to Pauli Strings.

Bug Fixes

• Fixed Clippy lints
• Added all missing examples to the cargo.toml file.

Potentially Breaking Changes

• Changed the Operator trait to require the Display trait.
• Changed operator addition methods on Pauli Strings to panic if an operator is added to a duplicate qubit.

Full Changelog: v1.3.0...v1.4.0

v1.3.0

What's Changed

• Added the circuit! macro for easy circuit-building using a simple DSL.
• Added crate- and mod-level documentation.
• Added the Matchgate operator, a two-qubit gate that simulates nearest-neighbour interactions in fermionic systems.
• Added the from_ry_phase method as an extension to the Unitary2 operator, allowing for safe, infallible construction of Unitary2 operators using angle parameters.

Bug Fixes

• Fixed Clippy lints
• Fixed bug in build_final that allowed for unchecked circuit building.
• Fixed bug in add_gates that allowed for unchecked gate addition to circuit.

Potentially Breaking Changes

• Removed unwrap() from the implementation of unitary gates, propagating the NonUnitaryMatrix error instead of panicking.
