SC479 - Introduction to Quantum Optics

Sunday, 05 May
13:30 - 17:30

Short Course Level: Beginner


Bahaa Saleh, CREOL, University of Central Florida, USA

Short Course Description:

This course is an introduction to quantum optics and its role in quantum information technology. It begins with a brief overview of the basic quantum principles — superposition, indeterminacy, non-clonability and entanglement. The quantum state of photon polarization will be used to describe these principles and introduce the qubit.

This will be followed by a description of the inherent uncertainty in the optical field amplitude, phase and quadrature components, and a summary of the photon statistics associated with various quantum states of light. Squeezed states of light will then be introduced along with their role in continuous-variable quantum technology.

The third segment of the course covers optics of the multimode single photon, including photonic implementation of modal quantum gates and applications to secure communication, e.g., quantum key distribution. This is followed by optics of two photons in an entangled state (biphotons) and optical systems for implementation of multi-photon multi-qubit quantum gates and circuits.

The fourth segment is devoted to multiphoton quantum correlation and interference and their applications to quantum sensing, metrology and imaging. The enhancement in sensitivity and resolution gained by use of nonclassical light will be highlighted.

Short Course Benefits:

This course will enable you to:

  • Explain the principal quantum principles underlying the quantum technology leap 
  • Explain the difference between entanglement and classical correlation resulting from shared information at birth
  • Explain the meaning of squeezing of light and its advantage in precision measurement
  • Compare the photon statistics and noise properties associated with various states of light
  • Compare single-photon optics to classical coherent optics
  • Compare two-photon optics to classical partially coherent optics
  • Determine the diffraction and interference properties of a single photon
  • Determine the diffraction and interference properties of a biphoton
  • Distinguish between classical and quantum ghost imaging
  • Identify the origin of the enhanced sensitivity in two photon interference
  • Delineate the advantages and challenges of photonic quantum logic gates
  • Become familiar with the jargon and basic issues pertaining to new advances in optical quantum information technology
Short Course Audience:

This course is intended for an audience with background in physics, electrical engineering or optical science/engineering, and an interest in learning about emerging quantum technology from an optics and photonics perspective.
