Book review: Quantum Processes and Measurements Claude Fabre | Review by Silvano Donati The quantum world has never been so fascinating and interesting regarding applications since new avenues of secure communication and computing have been demonstrated with photon entanglement and the qubit. This book offers self-contained and thorough coverage of the fundamentals of quantum processes, in 11 agile chapters and 11 appendices. Six chapters describe theoretical issues related to quantum systems and cover destructive and nondestructive photon detection, density matrix, evolution, quantum measurement, entanglement, Wigner functions and quantum metrology. The five chapters falling in the experiment category cover modern achievements like the detection of single quantum objects, quantum processes, bipartite systems, quantum fluctuations and parameter estimation and metrology. The appendices are useful for recall or excursus on quantum mechanics postulates, qubits, quantum electromagnetic...
