On Simultaneous Information and Energy Transmission through Quantum Channels
Bishal Kumar Das, Lav R. Varshney, Vaibhav Madhok
The optimal rate at which information can be sent through a quantum channel when the transmitted signal must simultaneously carry some minimum amount of energy is characterized. To…
Quantifying operator spreading and chaos in Krylov subspaces with quantum state reconstruction
Abinash Sahu, Naga Dileep Varikuti, Bishal Kumar Das +1
We study operator spreading in many-body quantum systems by its potential to generate an informationally complete measurement record in quantum tomography. We adopt continuous weak…
Unconventional topological phase transition from semimetal to insulator in SnBi2Te4: Role of anomalous thermal expansion
T. K. Dalui, B. Das, C. K. Barman +8
We propose SnBi2Te4 to be a novel candidate material exhibiting temperature (T) mediated transitions between rich topological phases. From a combined theoretical and experimental s…
