Microwave Photonics with Superconducting Circuits
Quantum information processing (QIP) is the research field which aims at exploiting quantum phenomena to revolutionise information technology and perform computations inaccessible to classical computers. Quantum states of light consisting of many entangled modes (multimode entangled states) provide a powerful quantum resource and have been proposed as a platform for universal quantum computing.
Photonic multimode continuous variable (CV) quantum states are routinely adopted at optical frequencies but they are still not established in the microwave regime, where one can take advantage of much higher non-linear interactions without introducing dissipation or dephasing. This research line addresses this challenge, aiming at generating and manipulating large multimode entangled states in the microwave regime. We use superconducting quantum circuits, specifically, Josephson meta-materials, to generate and control quantum correlations between frequency modes in microwave photons.
TruePA aims at developing the next generation of Traveling Wave Parametric Amplifiers (TWPAs), which are key tools for quantum technologies and basic sciences involving the detection of weak electromagnetic signals in the microwave domain. TruePA aims at pushing TWPA devices beyond current limits pursuing three main ground-breaking advances: demonstration of TWPAs which are (i) resilient to magnetic fields, (ii) quantum-noise-limited and (iii) fully nonreciprocal.
TruePA brings together internationally known researchers with complementary expertise in the field of superconducting circuits, quantum amplifiers, nanofabrication and quantum optics. This specialized knowledge is complemented by the expertise of two industry partners, to push a new generation of TWPAs to off-the-shelf components contributing to the growth of quantum technologies in Europe and at the same time pushing forward basic science research.
Out team is the Italian node of the consortium. Our contribution is mostly focused on WP2: development of truly quantum-noise-limited TWPAs.
The Institute is a consortium that teams up several Italian entities carrying out competitive and innovative research in the field of Quantum Science and Technology (QST).
Our team constributes to the SPOKE 5 which aims at developing Electron-based Platforms for Quantum Technologies.

This is a PRIN 2022 project funded by the Italian Ministery of Research. The project aims at developing Advanced Control and Readout of Scalable Superconducting NISQ Architectures. The project is coordinated by the University of Naples Federico II and involves two more unites: University of Catania and our CNR-SPIN Napoli unit.
Our team's contribution focuses of the development of optimal experimental protocols for the control and readout of superconducting qubits.
Quantum optics harnesses the states of photons and the properties of quantum light involving multiple modes (e.g. spatial, temporal, frequency or polarisation). It offers the potential for large-scale quantum computing in which each mode represents an individual quantum state or degree of freedom. This type of system has been realised for photons in the visible frequency range but it is not yet estabilished in the microwave range which has numerous advantages for quantum computing. The EU-funded MOSAiC project provided a first step to fill this gap with experimental demostration of two-mode entanglement in traveling microwave photons with a superconducting quantum circuit.
