Really excited about our new paper on quantum belief propagation (aka "belief propagation with quantum messages")!
arxiv.org/abs/2509.19441
Our new quantum algorithm solves a structured state discrimination problem which is central for quantum algorithm based on Regev's reduction (like DQI).

Efficient and optimal quantum state discrimination via quantum belief propagation
We present an efficient quantum algorithm for a structured state discrimination problem we call the subspace decoding task. Building on this, we show that the algorithm enables efficient and optimal d...

Hey all! Just uploaded my PhD thesis on the arXiv, which I recently defended in January. Feel free to check it out! 🤗
arxiv.org/abs/2503.21773
It's about quasiprobabilistic algorithms to simulate quantum circuits - not just on classical computers, but also on restricted quantum computers.

Simulating quantum circuits with restricted quantum computers
It is one of the most fundamental objectives in quantum information science to understand the boundary between the computational power of classical and quantum computers. One possible avenue to explor...
