“…First steps towards the development of heralded photon sources with low wavelengths compared with present day sources (in the visible and UV), have been achieved by Flurin et al [36] through the successful production of pairs of entangled electromagnetic fields in the microwave domain, using superconducting circuits made of Josephson junctions. Another encouraging progress towards radio heralded photon sources is the manipulation of energy-time entangled photons in optical fibers at telecommunication wavelengths, which has been demonstrated by Olislager [37]. One should also highlight that future work on developing tunable nanoantenna structures could eventually lead to 2D metamaterials to provide enhanced functionality for entanglement distillation of electromagnetic signals in the radio domain [38].…”

The possibility to use a Hong–Ou–Mandel (HOM) interferometer to carry out gravitational waves detection and spectrometry is investigated. The noise budget of the instrument is evaluated. The basic experimental requirements are calculated. It is shown that the power and wavelength of the heralded photon source, together with the angular accuracy of the measurement of the photon polarization rotation, form the main constraints to determine the type of gravitational waves sources, which would be the target of HOM gravitational wave spectrometers. The currently available pW power heralded photon sources, with typical heralded photon frequencies in the order of 1014 Hz (visible—UV part of the optical spectrum) are totally unsuitable, in terms of required detection time for any of the GW sources, which are presently targeted by ground and space based GW detectors. The operation of the HOM interferometer as a GW spectrometer is illustrated with a numerical model that uses the gravitational wave strain data recorded by LIGO on 14 September 2015 (GW150914 event). Assuming an angular accuracy of rad for the measurement of photons polarization rotation, these measurements could only be carried out with HOM interferometer’s arm lengths of the order of 10.000 km (only achievable in space, if we do not use optical cavities), and by using heralded photon sources of about 1 W power, producing heralded photons with wavelengths in the radio-wave band of the electromagnetic spectrum, 10 MHz. Although the technology to produce this type of heralded photon sources is currently not available, a brief discussion of the possible implementation of a large arm HOM interferometer in space is introduced.

“…Among various photonics observables, one also can use, for instance, frequency-bin or angular momentum qubits for quantum communication and processing. With frequencybin observable, qubit manipulation is done through the implementation of acousto-optical modulators or combinations of electro-optical modulators with optical filters [Olislager et al 2010b, Olislager et al 2010a, Olislager et al 2011, Ramelow et al 2013. Meanwhile, angular momentum qubits may not represent a household name, particularly in quantum communication.…”

This manuscript reports the development of fundamental resources for long distance quantum communication based on fibre telecom technology and non-linear optical waveguides. After a general introduction on quantum communication, the thesis is structured along three parts. The first part illustrates the development of two photonic polarization entanglement sources suitable for quantum networking. Both sources allow the generation of paired photons in the telecom C-band of wavelengths via spontaneous parametric down conversion (SPDC) in periodically poled lithium niobate waveguides (PPLN/W). The first source relies on type-II phase matching. In this configuration, two important elements, namely fiberbased walk-off compensation, and deterministic separation of the paired photons using lowloss, dense wavelength division multiplexing (DWDM) filters, are detailed. On the other picosecond pulsed telecom fiber laser, operating at 2.5 GHz repetition rate, acting as a master optical clock, enabling to accurately synchronize the emission of photon pairs in the telecom C-band of wavelengths at two remote locations. This innovative approach is applied for synchronizing two remote PLLN/W based sources operated at 2.5 GHz, and preliminary results on two-photon interference obtained with single photons coming from each source are shown and discussed.
