moleculAR maTerials for on-chip intEgrated quantuM lIght sourceS

Introduction

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.

Research Goals

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
• 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.

Methodology

The molecular quantum sources will be combined with suitably designed plasmonic supernanostructured cavities to achieve the highest optical enhancement. The proposed progress will be gained through:

1. Cutting-edge synthesis techniques
2. Advanced characterization methods
3. Integrated nano-photonics engineering strategies

Expected Outcomes

The devices and methods developed in this project will lead to photon sources with competitive performance in terms of:

• Coherence
• Efficiency
• Scalability
• Cost

This will lead to a fundamental breakthrough in the development of quantum technologies, paving the way to bring them out of the laboratory into the real world.

Consortium and Impact

The achievement of the high risk/high gain project goal requires intensive research activity in different scientific/technological areas, achievable thanks to a multidisciplinary consortium.

The right balance among:

• Competitiveness of the expected results
• Degree of technological innovation
• Future development

is essential. The outcomes and targets are expected to lead European research at the forefront of the second quantum revolution, thus contributing to Europe's position as a global leader in the field.
