Imaginarity-generating power of unitaries: A resource-theoretic approach
Akhil Kumar Awasthi, Mrinmoy Samanta, Sudipta Mondal +2
Imaginarity, stemming from the complex structure of quantum mechanics, has recently emerged as a fundamental resource, yet its dynamical generation remains largely unexplored. In t…

Hierarchies of Gaussian multimode entanglement from thermodynamic quantifiers
Mrinmoy Samanta, Sudipta Mondal, Ayan Patra +2
We develop a thermodynamic characterization of multimode entanglement in pure continuous-variable systems by quantifying the gap between globally and locally extractable work (ergo…

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…
