"XYZ ruby code: Making a case for a three-colored graphical calculus for quantum error correction in spacetime"

journals.aps.org/prxquantum/a...

This work presents a new highly attractive #Floquetcode in #quantumerrorcorrection and introduces - yet another - useful graphical calculus.

Extremely proud to see our paper "Quantum Convolutional Neural Networks are Effectively Classically Simulable" published in PRX Quantum

journals.aps.org/prxquantum/a...

This is an instantiation of our work, provable absence of barren plateaus implies classical simulability.

Our paper on creating an entangled Bell pair just came out in PRX quantum.
journals.aps.org/prxquantum/a...
We figured out a way to do a transversal logical cnot between two codes and created a logical Bell pair, despite not having anywhere near the right connectivity to do so.

Our paper on Solvable Quantum Circuits in Tree+1 Dimensions is now published in @prxquantum.bsky.social ! Very happy with how this work turned out, possibly even happier that the title made it through peer review.

Quantum metrology in the finite-sample regime

journals.aps.org/prxquantum/a...

We propose an operational framework of #quantummetrology in the practically meaningful regime of a few measurement samples, introducing probably approximately correct (#PAC) metrology.

What role do #measurements play in quantum algorithms? We systematically explore this question in the context of a greatly simplified #quantumalgorithm for the abelian hidden subgroup problem for states (#StateHSP), featuring a reduced circuit complexity.

The big question after the tutorial is whether I’m finally done drawing demons?

New paper out in #PRX_Quantum! 📃📃

We show when a heat-flow reversal is actually a signature of quantum nonclassicality as described by quantum generalized contextuality.
