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…
Disparity between multipartite entangling and disentangling powers of unitaries: Even vs Odd
Mrinmoy Samanta, Sudipta Mondal, Aditi Sen De
We compare the multipartite entangling and disentangling powers of unitary operators by assessing their ability to generate or eliminate genuine multipartite entanglement. Our find…
