Where You Measure Decides What You Measure: Position Selection in Ablation-Based SAE Evaluation
Valentin Noël
Sparse autoencoders are meant to name the things a language model computes, and the usual way to check that a latent matters is to switch it off and see what changes. But a latent…
Spin Chain Quantum Communication on a Trapped-Ion Processor
Madhumita Sarkar, Trinity Pointon, Sougato Bose
The authors experimentally implement spin‑chain quantum communication protocols on a trapped‑ion processor, showing that engineered coupling profiles improve state‑transfer fidelit…
Learning Topological Quantum Phases from Limited Subsystems
Mehran Khosrojerdi, Sougato Bose, Alessandro Cuccoli +3
Characterizing quantum topological phases requires measuring non-local string order parameters, demanding access to the full system, which is often experimentally unfeasible. In th…
Self-Attention for Quantum Entanglement Prediction
Anuj Gore, Roopayan Ghosh, Dylan Lewis +1
Quantum entanglement is a powerful resource for quantum-enhanced technologies. However, its reliable quantification remains challenging due to the exponential scaling of the Hilber…
Dynamics of many-body localized systems: logarithmic lightcones and -law of -Rényi entropies
Daniele Toniolo, Sougato Bose
In the context of the Many-Body-Localization phenomenology we consider arbitrarily large one-dimensional local spin systems, the XXZ model with random magnetic field is a prototypi…
All-Electric Quantum State Transfer via Spin-Orbit Phase Matching
Madhumita Sarkar, Roopayan Ghosh, Charles G. Smith +2
Semiconductor hole-spin qubits offer a promising route to quantum computation due to their weak hyperfine interaction, and strong intrinsic spin-orbit coupling enabling electric co…
