“Variational approach to photonic quantum circuits via the parameter shift rule”

In the current era of noisy intermediate-scale quantum computers, variational quantum algorithms represent one of the most viable approaches for their application to solve tasks of interest. These algorithms train a parameterized quantum circuit to execute a specific task encoded in a cost function that needs to be minimized using a classical optimizer. In this … Continua a leggere

“Modular Quantum-to-Quantum Bernoulli Factory in an Integrated Photonic Processor” just published in Nature Photonics

Generating and manipulating randomness is essential for numerous information technology applications, and quantum mechanics has been shown to offer distinct advantages in this area. A notable model for randomness manipulation is the Bernoulli factory, which enables the controlled adjustment of the bias in Bernoulli random processes. Initially, this framework was explored entirely within a classical … Continua a leggere

Quantum Lab at the European Researchers’ Night 2024
