Today, new preprint came out on arxiv.org/abs/2604.18506. In collaboration with the group of @JoseDMartin_UV @UV_EG we use physics-inspired neural networks to enhance quantum Fisher information in many-body metrology. @QuantumYue @icmm_csic

We develop a WNC ansatz together with an efficient local optimization strategy, enabling fast adiabatic preparation of 1D and 2D AKLT states. Our method makes CD scalable—demonstrating, for the first time, performance up to ~1000 qubits in 1D and 2D hexagonal lattices (3×10).

I was saddened to learn that Nobel laureate Tony Leggett has passed away. I still remember his visit at Shanghai University in August 2016…His physics superfluidity, dissipation in quantum phenomena, macroscopic entanglement in superconductors will live on!
