v0.43.0

(Full Changelog)

Highlights

This release marks the first step toward Virtual Distillation (VD) in Mitiq, with an initial helper function that vertically copies a circuit M times. A team of students at the University of Amsterdam worked for the month of January on implementing the technique that will be integrated into Mitiq over the coming releases. We also have a new tutorial thanks to @purva-thakre on combining Pauli Twirling and Zero-Noise Extrapolation!

We are currently testing Layerwise Richardson Extrapolation (LRE) on hardware, and work has begun on Probabilistic Error Amplification (PEA)---stay tuned for more updates in future releases!
