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…
Role of quantum state texture in probing resource theories and quantum phase transition
Ayan Patra, Tanoy Kanti Konar, Pritam Halder +1
Building on the recently developed quantum state texture resource theory, we exhibit that the difference between maximum and minimum textures is a valid purity monotone in any dime…
Expediting quantum state transfer through the long-range extended XY model
Sejal Ahuja, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Going beyond short-range interactions, we explore the role of long-range interactions in the extended XY model for transferring quantum states through evolution. In particular, emp…
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…
