Starting soon at noon (ET):
Speeding up state preparation with dynamic quantum circuits with Kevin Smith (Yale University and Brookhaven National Laboratory)
Join us live on the @Qiskit Seminar to ask questions and discuss

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.
arxiv.org/abs/2404.16083
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.
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!

A full interactive tutorial is included on the Bosonic Qiskit Github with many more details: github.com/C2QA/bosonic-qisk…

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.

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.

It's Quantum Thursday! Today (4/13) at 12 PM ET, @BrookhavenLab Research Associate Kevin Smith presents: "Using measurements to reduce circuit depth: Deterministic preparation of the AKLT state in constant-time on an IBM Quantum processor"

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!

We have also added a new tutorial over at the Github repo that walks through the examples in detail:

Then, Kevin Smith, from @Yale_QI , showed us how to use mid-circuit measurements and feedforward to prepare the AKLT state
Excited to share our new work:

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.
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.
