    sensitive experiment with an exquisite control of systematic errors Most of the experiments or projects dedicated to the quest are based on the well known direct imaging technology While imagers measure maps of the CMB interferometers directly measure Fourier components of the Stokes parameters and thus are expected to be less sensitive to systematic effects Unfortunately the classical heterodyne interferometry concept may have reached its limits in term of scale and sensitivity However Bolometric Interferometry could combine the advantages of interferometry in terms of systematic effects handling and those of direct detectors in terms of sensitivity Although many experiments are already proposed in the USA ground based and balloon borned only one project is emerging in Europe the QUBIC program supported by a French Italian USA UK Irish collaboration http www qubic org The APC CMB team including its experimental laboratory is leading this research effort with particular interest in Conception and design of the QUBIC instrument Data analysis and simulations Development of the detection chain Bolometer arrays based on the Transition Edge Sensors TES technology and multiplexed readout Kinetic Inductance Detectors KIDs a new path towards large detector arrays this new detection technique uses the variation of kinetic inductance of a superconductor when it absorbs a photon flux Their advantages are the following i they are relatively simple to fabricate ii the readout electronics is inherently multiplexed allowing for a large number of detectors of the order of 1000 or more to be readout with a single wire and iii the intrinsic sensitivity could theoretically be very high We propose to couple these new detectors with the current developments made for TESs Within 2 years a demonstrator of some 100s KIDs will be realized fully compatible with the QUBIC requirements The number of detectors will be further improved to reach some thousands of KIDs within 10 years Realization of receiver horns based on the platelets technology The goal is to achieve during the 4 coming years a complete design of the final instrument which means that it will be necessary to develop all the detector chain and choose between the 2 possible solutions we are working on KIDS and TES based arrays We will also have to build a prototype of the first module within 2 years in order to perform first observations on the sky and consequently to tune and improve the behaviour of this first module As developed in section 6 we intent to put the LABEX contributions on the KIDs development and on the conception and design of the instrument which is now well established but still needs some important effort in the data analysis aspects The description of the concept is on the process to be published and available on the archive QUBIC The QU Bolometric Interferometer for Cosmology E Battistelli et al astro ph 1010 0645 and submitted to AstroParticle Physics 3 Understanding the nature of Dark Energy The other sub work package has a different timeline it concerns the analysis of data of
