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…
Implementing efficient selective quantum process tomography of superconducting quantum gates on the IBM quantum processor
Akshay Gaikwad, Krishna Shende, Arvind +1
The experimental implementation of selective quantum process tomography (SQPT) involves computing individual elements of the process matrix with the help of a special set of states…
Using a quantum SWAP engine to experimentally validate thermodynamic uncertainty relations
Krishna Shende, Arvind, Kavita Dorai
Thermodynamic uncertainty relations (TURs) arise from the bounds on fluctuations of thermodynamics quantities during a non-equilibrium process and they impose constraints on the co…
State-independent robust heat-bath algorithmic cooling of nuclear spins
Krishna Shende, Arvind, Kavita Dorai
In this work, we experimentally demonstrate the implementation of a recently proposed robust and state-independent heat-bath algorithmic cooling (HBAC) method [1] on an NMR quantum…
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…
