New study presents a toolkit for describing complex quantum systems with long-range memory, crucial for controlling noise in quantum devices. The work paves the way for advanced numerical techniques and better understanding of diverse quantum systems.

Since there is a conjectured quantum Stein’s lemma to prove, a prize is in order. Hier ist ein Stein from Ulm, which we figured is the most appropriate prize. It will be delivered to the first person to provide a complete proof of Conjecture 2 here arxiv.org/abs/2205.02813

I’m excited to share a new paper I’ve been working and thinking on for quite a while now.
Non-Markovian dynamics have long been elusive to study (or even define) for a variety of reasons. We categorise, efficiently characterise, and control them all!🧵

Stoked for this work to be out!
Complex systems often display long-range correlations. There is a notion of fine/coarse-graining in a spatial setting through hierarchical tensor networks to capture the relevant physics--but what about temporally?

Wisdom from Scott Aaronson (1/2): “I think presenting to the public or to investors that we know how to get big quantum speed-ups for machine learning and optimization in the near future is fundamentally dishonest.”

I like how this platform, with its new name X, is fully embracing its status as the global leader in cancel culture.

Piece about our recent work
Trinity’s quantum physicists, led by @QuSysTCD, in collaboration with @IBMResearch Dublin have successfully simulated super diffusion in a system of interacting #quantum particles on a quantum computer.

I've put my lecture notes from my Fall 2022 Quantum Computation course online.

I don't guarantee that there aren't any mistakes left in them, although I've tried to eradicate them all. If you find any, feel free to email me.

PSA to address some takes: folks, your computers will still heat up a little, even if room temperature superconductors become a thing. That's due to Landauer's principle, which places a fundamental cost on performing irreversible computations (like an AND gate).
Good news:🧵

Very excited to share our method for simulating PDEs with quantum simulators! It is based on the Schrodingerisation framework for continuous-variables. We also have a new simulation protocol for PDEs with uncertainty 😄arxiv.org/abs/2308.00646

And no quantum supremacy there

Everywhere a lie-lie

This paper has lost IBM a lot of respect in the community - you can’t spin this away. Had it been posted on arXiv first the limitations of your classical comparison would have been discussed/exposed prior to publication, so why not?
