Surpassing Gaussian optimality in multiparameter estimation with indefinite causal order
Sudipta Das, Rivu Gupta, Aditi Sen De +1
We identify single-mode Gaussian probes, generated by displacement and squeezing operations on the vacuum state, which are optimal for the simultaneous estimation of displacement a…
Characterizing pairwise swapping capabilities of dense coding channels
Abhishek Muhuri, Nirman Ganguly, Aditi Sen De +1
We introduce a novel multipartite entanglement-assisted classical communication task, referred to as dense coding swapping, in which legitimate parties collaboratively swap the den…
Symmetric Equilibrium Propagation for Thermodynamic Diffusion Training
Aditi De
The reverse process in score-based diffusion models is formally equivalent to overdamped Langevin dynamics in a time-dependent energy landscape. In our prior work we showed that a…
Thermodynamic Diffusion Inference with Minimal Digital Conditioning
Aditi De
Diffusion-model inference and overdamped Langevin dynamics are formally identical. A physical substrate that encodes the score function therefore equilibrates to the correct output…
Dimensional advantage in network cooling with hybrid oscillator-qudit systems
Mrinmoy Samanta, Debkanta Ghosh, Rivu Gupta +1
We examine the cooling of networks of oscillators through repeated unitary evolution followed by conditional measurement on a finite-dimensional auxiliary system, coupled via Jayne…
