Quantum Optics: photons

Quantum Optics 2 (PHY 562) deals with the quantization of the electromagnetic field, the notion of photons, and the interaction between matter and quantized radiation. It addresses topics at the heart of modern quantum optics, from squeezed states of light to single-photon sources and entangled photon pairs, which play a key role in the emerging field of quantum information.

Topics covered:

• Quantization of the electromagnetic field: Hamiltonian formalism, canonical quantization
• Quantized free radiation: Quasi-classical states, squeezed states, single-photon states
• Heisenberg equations, interferometry beyond standard photon noise
• Quantized radiation-atom interaction; Spontaneous emission
• Nonlinear optics: Classical treatment, quantum treatment, twin photon pairs
• Optical Bloch equations; Weisskopft-Wigner treatment; Density matrix; Quantum effects in atom-laser interaction
• Photon entanglement; Applications in quantum information
