Offer Description
The candidate will be required to design the electronic circuitry enabling control of the photonic chip and utilize this photonic chip to implement a communication protocol.
The objective of this contract is to integrate an optical communication link onto the silicon platform for conducting quantum key exchange using the BB84 protocol on the polarization observable. To achieve this goal, it will require the development of key components, including electro-optic modulators and on-chip integrated systems for both rapid and slow polarization control.
Silicon photonics is garnering increasing interest, primarily for the development of integrated, compact, and low-power transceivers. In recent years, the ability to realize quantum circuits on the silicon platform has opened up a vast scientific domain with significant societal implications. For instance, quantum properties such as state superposition, wave-particle duality, entanglement, and direct manipulation of quantum states have led to extraordinary scientific advancements. Notably, one of these advancements pertains to the development of new functionalities in the field of quantum communications. This poses a major challenge in constructing all layers of future communication networks, aiming to secure data for individuals, businesses, organizations, and states. While it is well-known that the quantum properties of light can be harnessed to establish secure key exchange protocols between distant parties, the operational implementation of these protocols remains complex, cumbersome, and costly, hindering their deployment in data centers. This field, known as quantum cryptography, represents the quantum technology closest to practical applications, ensuring the secure exchange of encryption keys. In this context, the emergence of silicon photonics provides a way to overcome these challenges by offering solutions for integrating various optical and optoelectronic elements needed for this implementation. This is achieved through compact, stable, efficient, user-friendly devices that are compatible with telecom and datacom standards.
