Universal linear manipulation via routing and projective measurements
Alessio Baldazzi, Sonia Mazzucchi, Lorenzo Pavesi
Multiport interferometers with ports are basic devices in both classical and quantum photonics. Ideally, they implement a linear unitary transformation between the input and ou…
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…
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…
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…
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.…
Universal multiport interferometers for post-selected multi-photon gates
Alessio Baldazzi, Lorenzo Pavesi
We show how to use universal multiport interferometers' schemes in order to create photonic post-selected Controlled-Z and Controlled-Controlled-Z gates, which are equivalent, modu…
A linear photonic swap test circuit for quantum kernel estimation
Alessio Baldazzi, Nicolò Leone, Matteo Sanna +2
Among supervised learning models, Support Vector Machine stands out as one of the most robust and efficient models for classifying data clusters. At the core of this method, a kern…
Quantum Circuit Mapping for Universal and Scalable Computing in MZI-based Integrated Photonics
Yong Kwon, Alessio Baldazzi, Lorenzo Pavesi +1
Linear optical quantum computing (LOQC) offers a quantum computation paradigm based on well-established and robust technology and flexible environmental conditions following DiVinc…
Do different kinds of photon-pair sources have the same indistinguishability in quantum silicon photonics?
Jong-Moo Lee, Alessio Baldazzi, Matteo Sanna +5
In the same silicon photonic integrated circuit, we compare two types of integrated degenerate photon-pair sources (microring resonators or waveguides) by means of Hong-Ou-Mandel (…
