Current-based metrology with two-terminal mesoscopic conductors
Shishir Khandelwal, Gabriel T. Landi, Géraldine Haack +1
The traditional approach to quantum parameter estimation focuses on the quantum state, deriving fundamental bounds on precision through the quantum Fisher information. In most expe…

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…
