Extracting Work from Discrete Quantum Polytropic Processes
Vishal Anand, Swarup Kumar Giri, Avijit Misra +2
We establish an upper bound on extractable work for time-dependent, non-Markovian quantum heat engines operating with finite baths. This bound analytically isolates the distinct th…
Closing the Activation-Cone Blind Spot: Response-Time Probing and Unified Defense
Subhadip Mitra
Inference-time safety methods for large language models have proliferated, yet no systematic comparison exists. We evaluate five defense paradigms (no defense, static steering, CAS…
Kinematic budget of quantum correlations
Maaz Khan, Subhadip Mitra
The diversity of quantum correlations -- discord, entanglement, steering, and Bell nonlocality -- disappears at the kinematic level of observable second moments. By treating state…
Cross-Generational Transfer of Adversarial Attacks Reveals Non-Monotonic Safety Alignment in LLMs
Subhadip Mitra
Safety alignment in LLMs does not improve monotonically across model generations. Studying four generations of Google's Gemma family (7B-31B) with quality-diversity evolution (MAP-…
Quality-Diversity Evolution for Discovering Diverse Vulnerabilities in LLM Safety
Subhadip Mitra
Current approaches to LLM adversarial testing suffer from coverage gaps: manual red-teaming does not scale, LLM-as-attacker methods exhibit mode collapse, and gradient-based approa…
Cross-Platform Fused MoE Dispatch in Triton: Portable Expert Routing Without CUDA
Subhadip Mitra
Mixture-of-Experts (MoE) architectures power the majority of frontier large language models, but their inference is bottlenecked by irregular memory access patterns and expert rout…
