v0.39.0

Highlights

We've made updates to our documentation, beginning with the completion of the first section of the Pauli Twirling user guide, which offers a comprehensive introduction to this feature. Additionally, we've added a new tutorial on CDR (Clifford Data Regression) using Qrack as an efficient near-Clifford simulator. This demonstrates a workflow that harnesses the speed of Qrack in the CDR training phase, while providing users with an in-depth look at how to integrate Mitiq and Qrack effectively.

Highlights

🚀 As of this release, thanks to @natestemen, we are officially supporting Python 3.12 and dropping Python 3.9.

🌉 As part of UnitaryHack 2024, new contributor @NnguyenHTommy fixed a Qiskit to Cirq gate conversion error by implementing a fallback mechanism to decompose and transpile the Qiskit circuit into native Cirq gates.

🌀 Another Unitary Hacker, @EmilianoG-byte added functionality to simulate noise specifically on CNOT and CZ gates when using the Pauli Twilring technique to symmetrize errors.

🔉 As hinted in last release's spoilers, @purva-thakre has implemented the noise scaling functionality required for the Layerwise Richardson Extrapolation (LRE) technique, which allows a more fine-grained control over the amount of noise in circuits compared to the standard unitary folding method.

✨ Enhancements

v0.36.0

Version 0.36.0

(Full Changelog)

Highlights

Support for Qiskit 1.0: Mitiq now fully supports programs written in Qiskit 1.0, thanks to the contributions of André Alves!

Enhanced Package Requirements: We've clarified the requirements for frontend packages. Each frontend is now available as an "extra" within the Mitiq package. For instance, to use Mitiq with Qiskit, simply run:

pip install mitiq[qiskit]

and similarly for all other supported integrations.
This ensures compatibility between all dependency packages required by Mitiq for frontend integration and those in the user's environment.

Quantum Error Mitigation methods: Users can now discover the available quantum error mitigation techniques by executing:

mitiq.qem_methods()

This function provides an accessible way to understand the module naming of each technique supported by Mitiq.

Thanks to @andre-a-alves, @cosenal, @jordandsullivan, @Misty-W, @purva-thakre for the PRs in this milestone.

Enhancements

• Created method to get available QEM methods in mitiq (#2298) [@jordandsullivan]

v0.35.0

Version 0.35.0

In this milestone, we've continued our work to support Qibo by providing a new tutorial, adding related Qibo-conversion functionality to the API-doc, and added Qibo to our main list of supported frontends. We've also added the capability to use rotated randomized benchmarking circuits as part of the calibrator. These circuits provide expectation values ranging from 0 to 1 when measuring the probability that the output state is in the ground state. Having circuits with a wide range of expectation values is an important benchmarking task, and make a great test for finding the correct error mitigation technique/parameters. If you find any bugs/inconveniences in working with these updates make sure to open an issue so we are able to fix it ASAP!

This release also contains contributions from two new Mitiq contributors, and Unitary Fund team members Alessandro and Jordan! Welcome both, and looking forward to many more contributions! Well done making your first contribution so quickly 🏎️💨!

Version 0.32.0

Happy holidays, and happy (almost) new year!! ❄️☃️🎄🎊 This will be our last release of the year, and we'd like to thank everyone who has contributed to Mitiq over the past 12 months. We've accomplished so much in the way of error mitigation this year, and we couldn't have done it without the support and time given by the volunteers.
Thank you!

The calibrator logs have been revamped for to support result discovery and analysis. The Calibrator.run method now support two options: flat and cartesian to display the experiment results in either a linear fashion, or grid-like. Results here have been truncated for brevity.

New benchmarking circuits: mitiq.benchmarks now contains a function generate_random_clifford_t_circuit which does what it says on the tin. Special shoutout to new UF team member Farrokh Labib (@FarLab) for this contribution.

from mitiq.benchmarks import generate_random_clifford_t_circuit

clifft = generate_random_clifford_t_circuit(
    num_qubits=2,
    num_oneq_cliffords=5,
    num_twoq_cliffords=5,
    num_t_gates=5
)
print(clifft)

The Executor.run method now supports a single circuit instance in addition to a list for ease of use when working with a single circuit.

- executor.run([circuit])
+ executor.run(circuit)

Faster Tests! Working on Mitiq has never been easier to develop with a faster (by 36%) test suite.

Summary

This release contains several documentation improvements and some new additions.
The classical shadows documentation has been improved (including a tutorial!) by @Min-Li. The Pauli Twirling method is added to the user guide (thanks @Aaron-Robertson and @purva-thakre). There is a new tutorial applying both zero-noise extrapolation (ZNE) and Clifford Data Regression (CDR) to quantum simulation, for the 1D Ising chain, in Cirq, by @farzadkianvash, a new contributor! The documentation has been further improved and unified by @Misty-W and @natestemen.

In terms of additions, a new type of benchmark quantum circuits, "rotated" randomized benchmarking (RB) quantum circuits have been added by @Misty-W, for more general benchmarks.
