Optical interferometric tools for probing memory effects
Saheli Mukherjee, Bivas Mallick, Samyadeb Bhattacharya +2
Recent efforts to detect non-Markovian memory have become increasingly important, motivated by the broad relevance of memory effects in quantum information processing, metrology, a…
Extracting Work from Discrete Quantum Polytropic Processes
Vishal Anand, Swarup Kumar Giri, Avijit Misra +2
We establish an upper bound on extractable work for time-dependent, non-Markovian quantum heat engines operating with finite baths. This bound analytically isolates the distinct th…
Unravelling the non-Markovian spin-boson model and quantum quasi-Otto cycle
Shreyas Harshal Pradhan, Hadi Mohammed Soufy, Vishal Anand +3
We use the spin-boson model to describe the dynamics of a two-level atom interacting with Fabry-Pérot cavity modes. We solve the Schrödinger equation for the system-bath model with…
Quantum Thermal Analogs of Electric Circuits: A Universal Approach
Devvrat Tiwari, Samyadeb Bhattacharya, Subhashish Banerjee
In this work, we develop a panoramic schematic of quantum thermal analogs of electric circuits in the steady state regime. We establish the foundations of said premise by defining…
Exploring Non-Markovianity in Ergodic Channels: Measuring Memory Retention through Ergotropy
Ritam Basu, Anish Chakraborty, Himanshu Badhani +2
In this work we introduce and characterize a broad class of quantum operations with a unique fixed point, termed quantum ergodic channels. We derive Lindblad-type master equations…
Using Quantum Switches to Mitigate Noise in Grover's Search Algorithm
Suryansh Srivastava, Arun K. Pati, Samyadeb Bhattacharya +1
Grover's quantum search algorithm promises a quadratic speedup for unstructured search over its classical counterpart. But this advantage is affected by noise acting on the search…
