Realizing the Petz Recovery Map on an NMR Quantum Processor
Gayatri Singh, Ram Sagar Sahani, Vinayak Jagadish +3
The Petz recovery map is a central construct in quantum information theory, providing an explicit, channel-aware prescription for reversing the effects of noise. Unlike standard qu…
Experimental investigation of a quantum Otto heat engine with shortcuts to adiabaticity implemented using counter-adiabatic driving
Krishna Shende, Matreyee Kandpal, Arvind +1
The finite time operation of a quantum Otto heat engine leads to a trade-off between efficiency and output power, which is due to the deviation of the system from the adiabatic pat…
Simulating Three-Flavor Neutrino Oscillations on an NMR Quantum Processor
Gayatri Singh, Arvind, Kavita Dorai
Neutrino oscillations can be efficiently simulated on a quantum computer using the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) theory in close analogy to the physical processes realized…
Experimental investigation of coherence contributions to a nonequilibrium thermodynamic process in a driven quantum system
Krishna Shende, Kavita Dorai, Arvind
The work done when a system at thermal equilibrium is externally driven by a unitary control parameter leads to irreversible entropy production. The entropy produced can be thought…
