Abstract: QScale is a European research project, funded by the CHIST-ERA coordination. It is devoted to the development of advanced quantum communication technologies, specifically of quantum repeater architectures, which represent a major and timely challenge for the field of quantum information science and technology.

INO’s Experiments/Theoretical Study correlated:
Quantum light state engineering

The Scientific Results:
1) A high-fidelity noiseless amplifier for quantum light states
2) Adaptive detection of arbitrarily shaped ultrashort quantum light states
3) Two-color quantum memory in double-Lambda media
4) Towards higher precision and operational use of optical homodyne tomograms
5) Quantum process nonclassicality
6) Single-photon-added coherent states: Estimation of parameters and fidelity of the optical homodyne detection
7) Manipulating Frequency-Bin Entangled States in Cold Atoms
8) Generation of hybrid entanglement of light
9) Heralded noiseless amplification and attenuation of non-Gaussian states of light
