InQuRe

InQuRe Field testing an integrated quantum repeater node A quantum repeater-based internet can address our society’s need for secure communication and form the backbone for distributed quantum computing and sensing tasks. In order to address the scalability challenge, three key technologies have yet to be demonstrated. On one side, quantum error correction is required to…

EQUAISE

EQUAISE Enabling QUAntum Information by Scalability of Engineered quantum materials Future quantum applications require non-classical light sources that emit indistinguishable photons on-demand with high efficiency and purity. A stringent requirement for industrial applications is that these sources are fabricated via simple and cost-effective methods and, at the same time, be compatible with current photonic integration…

E2TPA

E2TPA Exploiting Entangled two-photon absorption – E2TPA Entangled two-photon absorption (ETPA) is a rapidly emerging technique for studying atoms and molecules, especially in low photon flux regimes. It has similarities to both classical single- and two-photon absorption techniques, which are cornerstones of modern optical imaging, but the quantum correlations, or photon-pair entanglement, also brings novel…

CVSTAR

CVSTAR Continuous-Variable Multi-User Quantum Key Distribution for 5G and distributed storage applications Quantum key distribution is a quantum technology providing cryptographic keys with future proof and therefore quantum-safe security. As a two-party protocol, quantum key distribution is usually used with direct point-to-point fiber connections. However, typical telecom infrastructures consist also of point-to-multipoint passive optical networks…

ConSpiQuOS

ConSpiQuOS Controlling Spins in Quantum systems in an Online Setting Semiconducting spin qubits have small sizes and incredible operation speeds, but using them for large-scale fault-tolerant applications has so far been prevented by material noise limiting qubit coherence and decreasing gate fidelity. However, their strong sensitivity to electric fields can be profited from if a…

ARTEMIS

ARTEMIS Neural networks controlling superconducting quantum circuits The ARTEMIS project aims at establishing and commercializing a radically new neural-networks-based quantum control approach. It will use reinforcement learning on real time experimental observations in order to overcome today’s main challenges in quantum computing – quantum error correction and optimal control. In this project we will develop…

ShoQC

ShoQC 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…

SiUCs

SiUCs 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. Microwave photons are used at every stage of quantum information protocols: qubit manipulation,…

ApresSF

ApresSF Application-ready superresolution in space and frequency The wave-particle duality of light introduces two fundamental problems to imaging: the diffraction limit and photon shot noise. With quantum information theory one can tackle both of them with a single holistic formalism: model the light as a quantum object, consider any quantum measurement, and pick the one that gives…
