Bio:

Segolene Olivier is currently leading the quantum photonics program at CEA-Leti for applications in quantum communications and quantum computing.
She received her PhD in 2002 from the University of Paris in the field of optoelectronics and was hired at CEA-Leti in 2003 as a process and device R&D engineer. She developped her expertise in various fields such as III-V integrated photonics, microelectronic interconnects and optical data storage before she joined the silicon photonics lab in 2012. Since then, she has led several projects in collaboration with academic or industrial partners, dedicated to the development of active and passive silicon photonics components, hybrid III-V on Si lasers and integrated transmitters on silicon for WDM telecom and datacom applications. From 2016 to 2019, she was coordinating H2020 European project COSMICC on the development of Tb/s Silicon photonics transmitters for CWDM communications in datacenters. In 2018, she started exploring new emerging applications fields and launched a research activity in integrated quantum photonics.

Abstract Tomorrow’s Cybersecurity:

The future advent of quantum computers poses a serious threat on the security of current encryption algorithms used to transmit sensitive data in our communication networks. Building quantum-resistant security is therefore essential. Quantum cryptography offers absolute security, guaranteed by the laws of quantum physics. First implementations of quantum secure communication links are being demonstrated worldwide with bulky quantum key distribution systems. Miniaturization of those systems through the development of integrated components and circuits is key for the future large-scale deployment of a global quantum communication network, compatible with the existing fibre infrastructure. This talk will review the main challenges associated with the development of silicon photonics quantum integrated components meeting the requirements of advanced quantum key distribution protocols.

Abstract Quantum Computing:

Photonic qubits are a promising approach for quantum simulation and computing, providing a number of key advantages, such as insensitivity to their environment, hence no decoherence, and high connectivity. Remarkably, the use of photonic qubits has recently led to the demonstration of a quantum computing advantage. On the path towards the development of a practical large-scale quantum computing hardware, silicon photonics provides a low-cost, robust and scalable technology. This talk will review the main challenges associated with the development of silicon photonics quantum integrated components for generation, encoding, processing and detection of photonic qubits.
