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…
Marked vertex search on disordered graphs with Rosenzweig-Porter phases
Sabyasachi Chakraborty, Tilen Cadez, Sonjoy Majumder +1
Quantum marked vertex search algorithms are known to outperform their classical counterparts, yet their behavior in the presence of disorder remains largely unexplored. Here, we ad…
Response of a dipolar BEC to Laguerre-Gaussian beam driven STIRAP
Deepu Singh, Hari Sadhan Ghosh, Arpana Saboo +2
Coherent light-matter coupling via STIRAP can offer a versatile route to nucleate quantized vortices in Bose-Einstein condensates through the orbital angular momentum transfer from…
Quantum circuit model for continuous-time quantum walks on random graphs
Sabyasachi Chakraborty, Rohit Sarma Sarkar, Sonjoy Majumder +1
Quantum-circuit implementations of continuous-time quantum walks (CTQWs) can provide an efficient route to model graph-based algorithms. However, constructing circuits that faithfu…
Rotation-triggered Kelvin-Helmholtz and counter-superflow instabilities in a three-component Bose-Einstein condensate
Susovan Giri, Arpana Saboo, Hari Sadhan Ghosh +2
Interfacial hydrodynamic instabilities in multicomponent superfluids provide a versatile platform to explore nonequilibrium quantum dynamics beyond classical fluid analogues. We st…
Dissipation in fermionic two-body continuous-time quantum walk under the steepest entropy ascent formalism
Rohit Kishan Ray, R. Srikanth, Sonjoy Majumder
Quantum walks play a crucial role in quantum algorithms and computational problems. Many-body quantum walks can reveal and exploit quantum correlations that are unavailable for sin…
