A new method to sense EM, gravitational, and other classical fields: Bell Quantum Signal Learning (Bell QSL). We exploit quantum entanglement in the *detector* for an advantage over any classical method! With the brilliant Jordan Cotler and Ishaan Kannan.

⚛️⚛️⚛️ Thrilled to share our new paper on quantum probe tomography!

In this work we ask:

Can one learn about a complex quantum system given only the ability to control and measure a single particle?

Excited to share two new papers on quantum gravity in de Sitter, coming at the problem from different angles:

A new perspective on the emergence of statistical behavior in chaotic quantum many-body systems is presented, establishing projected ensembles as a relevant tool for the characterization of information-theoretic properties. @JordanCotler, @RobertHuangHY

New paper with Annie Wei on quantum scars in quantum field theory. We find that classical (unstable) periodic orbits in field theory can be imprinted on energy eigenfunctions, and we analyze the underlying mechanism.

What are noisy intermediate-scale quantum devices good for? In a new paper https://t.co/xGDEQ77fSI joint with @JordanCotler, @RobertHuangHY, and @jerryzli, we define and study a new complexity class, NISQ, that captures the computational power of these devices 🧵 (1/n)

Our papers on learning quantum systems by employing time-reversal as a new learning resource are online, https://t.co/qCKf4R35jS and https://t.co/lxlaqaOybu, where in certain cases we prove an exponential advantage against conventional "time-ordered" measurements @JordanCotler

A correspondence between 3D worlds and 2D worlds offers a new perspective on quantum gravity in expanding universes. Read the commentary by @JordanCotler. https://t.co/J79mNh8sJW

Announcing a new paper:
"Renormalization Group Flow as Optimal Transport"
joint with @jordancotler!

We describe a systematic connection between renormalization and entropy minimization. This opens the door to new machine learning methods in physics.
