Robust certification of non-projective measurements: theory and experiment
Raphael Brinster, Peter Tirler, Shishir Khandelwal +7
Determining the conditions under which positive operator-valued measures (POVMs), the most general class of quantum measurements, outperform projective measurements remains a chall…

Simulating quantum instruments with projective measurements and quantum post-processing
Shishir Khandelwal, Armin Tavakoli
Quantum instruments describe both the classical outcome and the updated state associated with a quantum measurement. We ask whether these processes can be simulated using only a na…

Maximal steady-state entanglement in autonomous quantum thermal machines
Shishir Khandelwal, Björn Annby-Andersson, Giovanni Francesco Diotallevi +2
We devise an autonomous quantum thermal machine consisting of three pairwise-interacting qubits, two of which are locally coupled to thermal reservoirs. The machine operates autono…
