Coupled integrated photonic quantum memristors using a single photon source made of a colour center
Alessio Baldazzi, Roy Philip George Konnoth Ancel, Sebastiano Guaraldo +7
Photonic quantum memristors provide a measurement-induced route to nonlinear and history-dependent quantum dynamics. Experimental demonstrations have so far focused on isolated dev…
Resource-efficient variational quantum solver for the travelling salesman problem and its silicon photonics implementation
Alessio Baldazzi, Stefano Azzini, Lorenzo Pavesi
The travelling salesman problem is a well-known example of computationally-hard combinatorial problem for classical machines. Here, we propose a novel variational quantum algorithm…
A resource-efficient and noise-robust entanglement witness based on the swap test
Sebastiano Guaraldo, Sonia Mazzucchi, Alessio Baldazzi +2
Quantum entanglement is an essential resource for quantum technologies, and the controlled swap test provides a versatile tool for its detection and quantification. Here, we propos…
Four-Qubit Variational Algorithms in Silicon Photonics with Integrated Entangled Photon Sources
Alessio Baldazzi, Matteo Sanna, Massimo Borghi +2
Variational quantum algorithms are hybrid quantum-classical approaches extensively studied for their potential to leverage near-term quantum hardware for computational advantages.…
