The consortium is collaborating with other recipients of the 2022 EIC Pathfinder Challenge: Alternative approaches to Quantum Information Processing, Communication, and Sensing. The goal is to work together towards developing novel technologies and study their potential industrialization, accelerating their emergence. The sisters projects are the following:
- Veriqub: Efficient verification of quantum computing architectures with bosons
Quantum devices offer great promise for computation, cryptography, communication, and sensing. Alternative approaches to quantum information processing in which bosonic modes are the carriers of information have attracted increasing attention, because they offer a hardware-efficient path to fault-tolerance and scalability thanks to their inherently large Hilbert space. However, this poses the problem of providing rigorous guarantees of the correct functioning of these promising bosonic architectures, a task known as quantum verification. To date, this verification is performed by general-purpose tomographic techniques, which rapidly become intractable for large quantum systems. Thus, other methods are needed as quantum devices are scaled up to achieve real-world advantages.
“Veriqub will introduce a new approach to the verification of quantum computing architectures with bosons based on continuous-variable measurements. Veriqub’s technological toolbox will comprise two main elements:
- We will experimentally demonstrate the verification of multi-mode bosonic systems for optical and superconducting architectures well beyond the state-of-the-art, and provide the first demonstration of verified quantum computational speedup.
- We will develop a theory framework that defines the fundamental advantages of our contribution, putting special emphasis on identifying and verifying resourceful bosonic quantum devices.”
The Veriqub consortium comprises world leading scientific partners who are ideally positioned to achieve the ambitious vision of this project and build a state-of-the-art verification technology toolbox, enabling bosonic quantum computing architectures to scale up, and positioning Europe as a leader in this domain.

- Heisingberg: Spatial Quantum Optical Annealer for Ising Hamiltonians
HEISINGBERG aims to develop a novel information processing platform, based on the XY spin Hamiltonian, as a scalable energy efficient alternative to current state of the art quantum simulators, considering experimental, theoretical, algorithmic and control aspects. The project is designed to fully develop :
1) the core optoelectronic system hardware,
2) a novel approach to encode spins and control their mutual couplings,
3) custom-tailored algorithms for the optimisation of the annealing process as well as the optimal mapping of real-life problems,
4) a generalisation of the existing theoretical model to account for the quantum operation regime,
5) advances in experimental realisation and measurements for the quantum operation, and finally,
6) the development of dedicated control and interfacing software for the robust deployment of the machine.
- ARTEMIS: moleculAR maTerials for on-chip intEgrated quantuM lIght sourceS
ARTEMIS proposes fundamental research toward the development of integrable single and entangled photon sources based on metallorganic molecular compounds. The project is motivated by the urgent need for novel quantum sources with unprecedented versatility, flexibility and performance. This goal will be pursued by resorting to molecular materials, based on transition metal and/ or lanthanide ions with organic moieties, characterized by tunable linear downshifted emission as well as non-linear optical properties enabling on-demand single photons and entangled photon pairs/triplets generation. Such flexible and processable metallorganic materials will replace traditional quantum photon sources based on bulk inorganic crystals allowing for the direct integration of wavelength- tunable quantum sources on current devices. The molecular quantum sources will be combined with suitable designed plasmonic supernanostructured cavities to achieve the highest optical enhancement. The proposed progress will be gained through cutting- edge synthesis techniques and advanced characterization methods integrated with nano-photonics engineering strategies. The devices and methods developed in this project will lead to photon sources with competitive performance in terms of coherence, efficiency, scalability, and cost. The achievement of the high risk/high gain project goal requires continuous feedback among molecular chemistry, linear and nonlinear optical characterizations, and quantum measurements. It is important to underline the high interdisciplinary feature of the proposed project thanks to the involvement of high-qualified scientific staff working in fields ranging from chemistry to quantum optics through physics, plasmonics and imaging. It is generally expected that the strong interdisciplinary character of the staff involved can make a significant contribution to development of innovative methods and techniques as well as make more simple collaboration with other projects in the Quantum Portfolio.
- Q-One: Quantum Optical Networks based on Exciton-polaritons
Q-ONE aims at exploring a novel approach for sensing and generating quantum states of light. The project idea places itself at the frontier between quantum physics and applied artificial intelligence. The consortium targets the realization of a novel device based on strongly interacting photons (exciton-polaritons) that, using principles of neuromorphic computing, is able to recognize, characterize, and generate a variety of quantum states. We propose to exploit the properties of a quantum neural networks (QNN) of polariton nonlinear nodes, using state-of-the-art interactions, to dentify and generate quantum states: this strongly innovative idea relies on the resonant injection of states as excitations of the QNN, which physically realizes–rather than simulates–a massively parallel computing task.
