New paper!
We show that a broad class of matrix product states can be exactly prepared using constant-depth quantum circuits with mid-circuit measurements and feedforward. This beats out the fastest possible preparation with unitary circuits alone.

We also provide specific conditions that an MPS must satisfy to be preparable with our scheme. Special shoutout to co-first author Abid Khan for helping me figure all of this out, and for teaching me a lot of group theory along the way.

Thanks also to co-authors Steve Girvin, Tzu-Chieh Wei and Bryan Clark, as well as everyone who I have discussed this work with over the past year.

Curious about bosonic error correction? Check out our blog post (led by the very talented Zixiong Liu) where we demonstrate the binomial kitten code in Bosonic Qiskit!

Happy and proud to announce that our paper on the "Dual-rail encoding with superconducting cavities" is now published in PNAS (pnas.org/doi/10.1073/pnas.22…)

Excited to see this appear in PRX Quantum!
We show that the AKLT state -- a prototypical example of a matrix product state and a SPT phase -- can be prepared in constant depth by using midcircuit measurements and feedforward.

A class of symmetry-protected topological states relevant for measurement-based quantum computation is shown to be constructible using only constant-depth quantum circuits by leveraging symmetries, midcircuit measurements, and feed forward. @_quks_

Excited to share our new work:
arxiv.org/abs/2210.17548
We show (w/ experiments included!) that the AKLT state can be deterministically prepared with a constant-depth circuit mid-circuit measurements, a major speed-up over known methods that all require times that scale w size.

We often think of qubits or “quantum bits” as the fundamental building block of quantum computing, but with the new Bosonic Qiskit package, we’re inviting users to explore a new quantum paradigm. Read more in our latest for the Qiskit blog: qisk.it/3YO5z6S (1/5)

Check out our new blog post on Bosonic Qiskit, an extension to @qiskit developed within @C2QAdvantage that allows you to simulate bosonic modes alongside qubits. Lots of worked examples included!

In addition to measurements of string order and entanglement spectra, we also carry out a quantum teleportation protocol using AKLT states prepared with our measurement-assisted algorithm.

S/o to coauthors Ella Crane, Nathan Wiebe, and Steve Girvin. It was a lot of fun working on this with all of them.
