Wigner's friend. Coincidentally also the Head of the Quantum Computing Group at Wigner RCP. Occasionally hired for the indirect observation of measurements.
Great! Huge congrats!

Great! Huge congrats!
With Bence and Zoli, we were able to train Fermionic Born Machine circuits even in the range of 120–160 qubits quite easily, but stay tuned for further improvements to our training methods, where we aim beyond 1000 qubits… 6/6

Our model builds on previous work on the hardness of Fermion Sampling (fermionic magic states + fermionic linear optics) with @michaloszmaniec.bsky.social (Michal Oszmaniec), Mauro Morales, and Ninnat Dangniam 5/6

Together with my two fantastic PhD students, Bence Bakó and Zoltán Kolarovszki, we now introduce a second compelling quantum generative model that is also (potentially) hard to sample from classically, yet can be trained classically. 4/6

In that they show that generative models based on IQP circuits can be trained efficiently on classical hardware, while classical sampling remains hard - offering a potential computational advantage and at the same time resolving issues related to quantum gradient estimation. 3/6

Train on classical, deploy on quantum: scaling generative quantum machine learning to a thousand qubits
We propose an approach to generative quantum machine learning that overcomes the fundamental scaling issues of variational quantum circuits. The core idea is to use a class of generative models based ...

No-go theorems for sublinear-depth group designs
Constructing ensembles of circuits which efficiently approximate the Haar measure over various groups is a long-standing and fundamental problem in quantum information theory. Recently it was shown th...

Yes, at least the HTML papers got visibility 😀.
Btw, the pdfs were in deed back in the afternoon. Thx, for reacting fast!

The central idea of our work is that the difficulty of counting degrees of freedom in quantum gravity has a nice quantum info analogue: Verifying the size of a Hilbert space with qubit operations ("overlapping qubits problem") .
Stay tuned for further works on this!
