Quantum photonics is one of the key players in the ongoing second quantum revolution. On one hand, photons are the natural carrier to transmit quantum information and as such are important in quantum communication and cryptography. On the other hand, photons can be used to perform simple quantum computation and simulation tasks. For most of these applications, high-dimensional quantum states, so-called qudits, are beneficial as they allow to benefit from an enlarged underlying Hilbert space. One powerful way to encode qudits is to use complex transverse spatial structures of light, i.e. structured photons.

In this webinar hosted by the OSA Quantum Computing and Communication Technical Group, Robert Fickler, Tampere University, will introduce the concept of structured photons, how they can be utilized as high-dimensional quantum states and review the current progress in the field. Fickler will then focus on how to modulate structured photons through multi-plane mode conversion techniques and how this can be beneficially applied to quantum information tasks.

What You Will Learn:

  • The concept of structured photons and how they can be utilized as high-dimensional quantum states.
  • Current progress in the field.

Who Should Attend:

  • Undergraduate students, graduate students, faculty, post-docs, and group leaders interested in the topic.

Professor Robert Fickler is the leader of the research group "Experimental Quantum Optics" at Tampere University, Finland. In which the research focuses on structuring single photons to realize high-dimensional quantum states, quantum interference, and entanglement. He obtained his Ph.D. at the University of Vienna and the Institute for Quantum Optics and Quantum Information (IQOQI), Vienna, Austria. His Ph.D. thesis “Entanglement of Complex Structures of Photons” supervised by Anton Zeilinger received the Springer Thesis Award 2015 due to the outstanding research. Robert Fickler has been a Postdoctoral Researcher in the Institute for Quantum Optics and Quantum Information (IQOQI), Vienna, Austria, and in the University of Ottawa in the research groups of Prof. Robert Boyd and Prof. Ebrahim Karimi. He has been acknowledged with several awards as the "Young Scientist Award 2015", "Banting Postdoctoral Fellowship 2016" and "Outstanding Postdoctoral Research Fellow 2016-17".
