It's comprehensive, and covers a wide range of topics in the discipline. We used this in a quantum optics course to great effect. One person found this helpful.

Simply an excellent book, both for teaching - and for reference. The clarity of the explanations - and the math - has kept editions of this book beside me for decades. The book is really nice, I highly recommend if you are in looking for fun and training for Olympiads and physics contest.

This is a decent book. I'd agree that it can be dry and focused on equations more than physics at times, but it offers a very balanced selection of topics, and clearer explanations than many physics books.

I particularly like the progression from old quantum theory to semiclassical theory to the fully quantized theory. It emphasizes the useful aspects of each theory, in particular the usefulness of the old theory in terms of simplicity and accuracy in many situations.

History may not always be the best approach to science, but it works if you emphasize the usefulness of simple models and how they follow from more sophisticated models. For an introduction to quantum optics, the author is to be highly commended for keeping the mathematics and derivations straightforward and easily followed by a senior or 1st year graduate student in experimental physics.

Unfortunately, he does not go beyond the math to discuss the physics which the mathematics describe. The problems he includes for students to work out are all derivation of formula with absolutely no application of formula.

By the time I got through the book, I realized that I still had no real intuition of how a laser worked, or any understanding of how to apply the quantized radiation field to any real-world problems. So if you're looking for a handbook to give you a simple tour of the mathematics in the quantum theory of light, this is the book for you.

If you're looking for a more comprehensive treatment, look elsewhere.

Undergraduate Quantum Optics: the Challenge, and the Excitement

A 53, A 54, Dung, H. A 57, Sommerfeld, A. Stratton, J. The excitation of one photon in a single travelling mode is frequently considered in the discussion of interference experiments, for example Young's slits or the Mach—Zehnder interferometer. Each spatial mode in these systems includes input light waves, both paths through the interferometer, and 2 Introduction: The photon output waves appropriate to the geometry of the apparatus.

A one-photon excitation in such a mode is distributed over the entire interferometer, including both internal paths. Despite the absence of any localization of the photon, the theory provides a relation between the input and output spatial distributions, equivalent to a determination of the interference fringes.

The fringes are the same in the classical and quantum theories, essentially because the spatial modes are identical.

The single-mode picture is not strictly valid in the conditions of practical one-photon interference experiments but its use has acquired respectability from some distinguished contributions to the discussion, for example Dirac [3] and Frisch [4].

The frequency separations beween discrete spatial modes are much smaller than any other characteristic frequencies for light beams in most open systems.

The discrete modes then effectively condense to a continuum and the systems are more rigorously and conveniently treated by a continuous-mode theory. The typical quantum-optical experiment produces one- or two-photon excitations described by a spatial wavepacket, with some degree of localization.

The wavepacket function is expressed as an integral over contributions from waves with a range of frequencies, or wavevectors. It is no longer so straightforward to explain what is meant by a 'photon' ; the level of excitation of the system continues to be represented by a number operator with integer eigenvalues, but the mean energy of the one-photon wavepacket is given by h times an average over its frequency components.

The one-photon state has, however, the important and distinctive property that it can produce only a single current pulse in the ionization of a photodetector. The concept thus survives as an operational definition in terms of photon detection and it provides a useful qualititative description of the nature of the state. As a general comment on the notion of interference in quantum mechanics, the effect occurs in general for experiments in which the probability of a given observation is given by the square modulus of a sum of two or more probability amplitudes [5].

Each such probability amplitude represents a contribution to a given output state from the same input state. In the customary photon description of quantum-optical interference experiments, it is never the photons themselves that interfere, one with another, but rather the probability amplitudes that describe their propagation from the input to the output. The two paths of the standard interference experiments provide a simple illustration, but more sophisticated examples occur in higher-order measurements covered in the main text.

Loudon R. The Quantum Theory of Light

In , Einstein [2] showed how the photoelectric effect could be explained by the hypothesis of a corpuscularity of electromagnetic radiation. The quantum of radiation was named a photon much later [3], in The work of Planck and Einstein stimulated much of the early development of quantum mechanics.

Another main stream in the initial formulation of the quantum theory was concerned with the interpretation of atomic spectral lines.Each photon has a more-or-less uniform spatial distribution within the cavity, proportional to the square modulus of the complex field amplitude of the mode function. site Drive Cloud storage from site. The photoelectric effect itself was shown [8] to be well described by the so-called semiclassical theory, in which the atomic part of the experimental system is treated by quantum theory but classical theory is used for the radiation.

They can be treated by means of a simple phenomenological theory due to Einstein [4].

The nth excited state has n quanta of energy ha in addition to the zero-point energy. The nature of the field correlation function and hence of the interference fringes depends on the kind of light incident on the interferometer.

Hopfield, J. Unlike its classical counterpart, a quantum harmonic oscillator of angular frequency co can only be excited by integer multiples of hco, the integers n being eigenvalues of the oscillator number operator.

The atom is no longer in a pure state of the form shown in eqn 2.
