Ⅱ.Purpose : MIQC is a metrology framework that will foster development and market take up of quantum communication technologies in particular Quantum Key Distribution technologies. The resulting metrology tools will help the QKD industry improve and maintain their products.
Ⅲ. Contents
* Provision of the measurement framework for the characterisation of photon emitters being developed for QKD.
- Photon emitters statistics will develop techniques for traceable measurement of the mean and variance of the photon number per pulse emitted by a QKD source.
Different techniques will be investigated.
- Spectral, temporal and polarisation properties of photon emitters will deliver measurements of wavelength, bandwidth, polarisation and pulse jitter for attenuated laser QKD sources. Furthermore, it will demonstrate techniques for polarisation state reconstruction.
- Single-photon properties of emitters will evaluate the quantities used by the quantum information community to characterise single-photon sources
* Investigation of the connection between fibre properties and decoherence of photon state used as information carrier, by developing a QKD testbed.
- Fibre properties relevant to State Propagation will investigate the evolution of the
state induced by the propagation in fibre.
- State preparation/detection will characterize devices used for state preparation and detection like Random Number Generators and Phase Shifters.
- Realization of an optical fibre based QKD test-bed will realize a QKD test-bed (a fiber link) with modular structure
- Measurement devices for in-line calibration of QKD systems will be realised.
* Provision of the measurement framework for the characterisation of photon detectorsdeveloped for QKD.
- Detection Efficiency of Commercial Single-Photon detectors for QKD
- Relevant properties of Commercial Single-Photon Detectors for QKD
- Detection efficiency characterisation of PNR detector based on tree configuration
- Primary reference for calibrating single-photon receivers
Ⅳ.Expected contribution
- MIQC will set the foundations for a robust quantum industry that will provide a step change in the telecoms industry and future proof data management that will ultimately impact on us all.
- MIQC will support the development of metrological capacity.
- MIQC will help the integration of the European Metrology.
- MIQC will make the social network between KRISS and European metrology scientists
