Efficient training of a 128-modes 3D continuously coupled photonic chip via limited quantum resources

Integrated photonics provides a promising route towards the development of large-scale, stable and low-loss quantum hardware. Existing implementations of universal quantum photonic chips generally rely on architectures consisting of localised interactions between the modes that can be programmed with known algorithms to implement specific operations. Recent advances have shown that interferometers based on 3D continuously … Continua a leggere

Two new PhD students join Quantum Lab!

The Quantum Lab team is excited to welcome two new members: Lorenzo Iasenzaniro and Giulia Lelli, both recently graduated in Physics at La Sapienza University of Rome, who join the group as PhD students starting this November.  Lorenzo’s research focuses on harnessing quantum properties of light to implement novel computation protocols and platforms.

Quantum Simulation of Electronic Structure using Quantum Density Functional Theory on a Programmable Integrated Photonic Circuit

Quantum simulations of molecular electronic structure hold the potential for computational advantage but are inherently limited by the linear scaling of qubit requirements with respect to system size. Quantum Density Functional Theory (Q-DFT) addresses this constraint by reformulating the interacting many-body problem in terms of a non-interacting Kohn–Sham reference system. Here, we present and experimentally validate … Continua a leggere

Multiparameter quantum-enhanced adaptive metrology with squeezed light out in Nature Communications

Squeezed light enables quantum-enhanced phase estimation, with crucial applications in both fundamental physics and emerging technologies. To fully exploit the advantage provided by this approach, estimation protocols must remain optimal across the entire parameter range and resilient to instabilities in the probe state. In this context, strategies that rely on pre-calibrated squeezing levels are vulnerable … Continua a leggere
