Quantera Call 2019 Funded Projects

Quantum Computation with Schrödinger cat states

This project seeks to establish a radically new, alternative approach to realizing the fundamental building blocks of quantum computers with superconducting qubits. In the next 3 years, we plan to employ only a handful of realistic components to realize robust error-corrected logical quantum bits.

Quantum information and communication with high-dimensional encoding

High-dimensional (HD) photonic quantum information (QI) promises considerable advantages compared to the two-dimensional qubit paradigm, from increased quantum communication rates to increased robustness for entanglement distribution. This project aims to unlock the potential of HD QI by encoding information in the spectral-temporal (ST) degrees of freedom of light. We will develop matched experimental tools and theoretical architectures for manipulating and characterizing such states, and we will demonstrate their use in applications.

SECuRe quantum communication based on Energy-Time/time-bin entanglement

Quantum communications (QC) is one of the main areas of the broader field of Quantum Technologies. The most well-known application of QC is in communication security, where huge progress has been observed since the first demonstrations of quantum key distribution (QKD). Another important application of QC is as the support backbone for future networks of quantum computers, the so-called Quantum Internet.

Short-range optical Quantum Connections

The project is concerned with the possibility of connecting heterogeneous quantum devices in a room, a building, or between buildings on a campus or in a limited neighbourhood. The challenge is to develop optical quantum connections versatile enough to connect different physical quantum platforms and faithfully carry a broad range of quantum states including discrete and continuous-variable Gaussian or non-Gaussian states.

Superinductor-based Quantum Technologies with Ultrastrong Couplings

Superconducting quantum circuits form one of the most promising solid state platforms for quantum computing. This success builds on the naturally large interaction between light, represented by microwave signals, and matter, embodied by superconducting qubits.
