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.

ALT A diagram representing a coarse-graining scheme for constructing a process tree from an influence matrix. It shows a 2D grid-like tensor network, with square plaquettes highlighted in red dashed lines. The bottom row contains green nodes, representing the “system” component of the influence matrix. The axes are labeled "Time" (horizontal) and "Space" (vertical).

A unifying operational characterization of quantum chaos is proposed using the formalism of multitime quantum processes. @DowlingNeil_ @modikk @MonashUni @Monash_Science

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 – at Wicklow, Ireland
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

A wonderful tribute to Göran Lindblad!

No quantum advantage here
And no quantum supremacy there
Here a qubit, there a qubit
Everywhere a lie-lie
