The solution must demonstrate the synchronization of local interferometers and the stabilization of their interconnecting optical link for the real-time readout of non-local quantum states.Challenge StatementQuantum correlation present among the particles of light promises improved metrological measurements with precision beyond what is achievable by classical resources. National Research Council (NRC) has recently established the source of entangled photons at Metrology Research Centre (METRO) in order to push the measurement precision limit in Optical Metrology to what is guaranteed by quantum physics. In measuring quantum entanglement between spatially distributed photons, it is critical to ensure synchronizing a readout-phase between local interferometers as quantum state analyzers (QSAs) and stabilizing their interconnecting optical links against thermal and/or mechanical fluctuations, within the coherence of participating photons. NRC is hence seeking innovators who could build active feedback system(s) for quantum channel stabilization and analyzer synchronization. Together, the resulting system, will enable robust and faithful observation of space-separated quantum states, and will eventually be integrated into quantum network prototype based on three-photon entanglement that NRC is currently developing as a fundamental building block for a scalable quantum Internet. Anticipated applications of the prototype include quantum secret sharing between three users and networked quantum information processing with multiple quantum sensors distributed over a distance.Desired outcomes and considerationsEssential (mandatory) OutcomesThe proposed solution must:Consist of a minimum of four interferometers (three optimized for quantum signals centered at 1550.00 +/- 0.05 nm, and one optimized for a pump signal centered at 775.00 +/- 0.01 nm).Be able to actively stabilize and control an optical phase within 0.001 radians.Have negligible crosstalk noise (greater than 80 dB isolation) from phase-locking laser on quantum signals.Yield a high throughput (each interferometer must have a transmission of greater than 80%).Have the ability to tune path-length difference of each interferometer at least 10 millimeters with 1 micrometer precision.Be able to stabilize relative temporal fluctuation of photon between two spatially separated interferometers on the order of picoseconds.Be able to stabilize relative temporal fluctuation of photon among all interferometers on the order of picoseconds.Be scalable with additional interferometers.Additional OutcomesThe proposed solution should:Be capable of monitoring phase of interlocked interferometers using Labview or Python.Be capable of monitoring temperature of all individual interferometers.Be capable of monitoring relative arrival time of photons at each interferometer using Labview or Python.Background and ContextOptical channel stabilization is essential for the realization of quantum networks as local quantum nodes are interconnected by interfering independent photons travelled from each network node. This photonic interference measurements require all participating photons indistinguishable in their degrees of freedom (DOFs), i.e. frequency, polarization, space and time. Compared to other DOFs, stabilizing the arrival time of photons, within their typical coherence of O (1 - 10 ps), is nontrivial due to sudden and large thermal and/or mechanical fluctuations throughout the entire system. Such a high-precision time-stabilization system could be expensive and labour intensive as separate hardware (lasers and photon detectors) and feedback mechanism are needed to be integrated into the main quantum system. Therefore, the development of an innovative solution to this problem through the IRAP-ISC challenge program would be time- and cost-effective, and would further support the quantum industry in Canada. Until now, no commercial solution has been provided by enterprises.ENQUIRIESAll enquiries must be submitted in writing to TPSGC.SIC-ISC.PWGSC@tpsgc-pwgsc.gc.ca no later than ten calendar days before the Challenge Notice closing date.
