The mass network integration of devices and environmental monitors predicted by experts for the near-future , in addition to the already rapidly increasing demand on bandwidth, will require technology that can facilitate and enable this social transition: an Internet with perfect security for large amounts of sensitive data (e.g. personal, health, or bank transactions), as well as the high data computing and processing power to handle these "big data." The continuously growing field of quantum optics shows high potential towards supporting a solution for these important demands mainly aimed at the development of perfectly secure quantum communication systems and ultrafast quantum computers based on photonics platforms. In this regards, optical quantum sources emitting so-called time-bin entangled quantum states are of significant importance to realize such systems, as they are compatible with current IT infrastructure. With this six-month engage project we aim to offer an innovative versatile solution to the generation and characterization of these important quantum states by developing an actively stabilized unbalanced fiber-optical interferometer for the quantum state generation and, relying on this, a tomographic quantum state characterization system. The proposed project will thus allow the researchers from the INRS-EMT, in collaboration with their industrial partner (OptoElectronic Components Inc.), to lead Canadian efforts in developing the very basis for this next technological revolution. The project will address the issue of the optical stability necessary for achieving a widespread use of time-bin entangled qubits. The developed devices will be robust, compact and universally applicable to any quantum source, thus constituting the ideal prerequisite for a successful commercialization through our industrial partner. The new knowledge generated from this project and the training of highly qualified personnel associated to this work will contribute to enhance Canada's global competitiveness in the most advanced high-technology sectors.
