Exploiting overcompleteness of Platonic-solid POVMs for shadow estimation
Dario Melegari, Stefano Mangini, Keijo Korhonen +2
Accurately estimating expectation values of observables from a finite number of measurement shots is a central challenge in quantum information science. Informationally overcomplet…
Resource reduction for variational quantum algorithms by non-demolition measurements
Dario Melegari, Rabia Abdul Razaq, Giovanni Minuto +1
We present a comparative study of two implementations of a variational quantum algorithm aimed at minimizing the energy of a complex quantum system. In one implementation, we extra…
Quantum simulations of macrorealism violation via the QNDM protocol
D. Melegari, M. Cardi, P. Solinas
The Leggett-Garg inequalities have been proposed to identify the quantum behaviour of a system; specifically, the violation of macrorealism. They are usually implemented by perform…
A Novel Approach to Reduce Derivative Costs in Variational Quantum Algorithms
Giovanni Minuto, Dario Melegari, Simone Caletti +1
We present a detailed numerical study of an alternative approach, named Quantum Non-Demolition Measurement (QNDM), to efficiently estimate the gradients or the Hessians of a quantu…
