Syllabus
- Week 1 - Quantization of light: one mode
In this first lesson, you will discover what is canonical quantization, apply it to the quantization of a single mode of the electromagnetic field, and find that it behaves as a quantum harmonic oscillator. The notion of photon will then naturally emerge, as ... - Week 2 - One photon state in a single mode: particle-like behaviour
In this lesson, you will discover how the quantum optics formalism leads to the particle-like behaviour of a one photon wave-packet. For this, you will have to learn the quantum optics expressions of the simple and joint photodetection signals. A comparison wi... - Week 3 - One photon interference: Wave-Particle duality
In this lesson, you will address the fascinating question of a single photon interfering with itself, by calculating the interference pattern for a single photon launched into a Mach-Zehnder interferometer. In order to do it you will first learn how to treat a... - Week 4 - Multimode quantized radiation: quantum optics in a real lab
In the real world there is nothing like purely monochromatic radiation. A correct description of radiation necessarily involves several modes. In this lesson, you will learn how canonical quantization can be easily generalized to the case of several modes, and... - Week 5 - One photon sources in the real world
One photon sources are important components in quantum optics, both in research laboratories and in applied quantum technologies. The lesson of this week will present the various kinds of one-photon sources available today, from heralded one photon sources to ... - Week 6 - Wave-particle duality for a single photon in the real world
You are now ready to develop the description of a real experiment , which was the first one to reveal directly the dual nature -- wave and particle, of a real single photon wave-packet. You will not only be able to describe, with the formalism you have learned... - Week 7 - One-photon based quantum technologies
In this lesson, you will discover two quantum technologies based on one photon sources. Quantum technologies allow one to achieve a goal in a way qualitatively different from a classical technology aiming at the same goal. For instance, quantum cryptography is...

École Polytechnique combines research, teaching and innovation at the highest scientific and technological level in the world to meet the challenges of the 21st century. The leading French engineering school for over 200 years, its training promotes a culture of multidisciplinary scientific excellence, open to a strong humanist tradition.
It was founded in 1794 by the French National Convention under the name École centrale des travaux publics, and militarised in 1804 by Napoleon I. Originally located in Paris, the school has been in Palaiseau (Essonne) since 1976, at the heart of the Paris-Saclay technology cluster. It has the status of a public scientific, cultural and professional establishment (EPSCP-GE), is a military grande école whose engineering course is supervised by the Ministry of the Armed Forces and is a founding member of the Paris Polytechnic Institute.
