Measurement of the Temperature Using the Tomographic Representation of Thermal States for Quadratic Hamiltonians
The Wigner and tomographic representations of thermal Gibbs states for one- and two-mode quantum systems described by a quadratic Hamiltonian are obtained. This is done by using the covariance matrix of the mentioned states. The area of the Wigner function and the width of the tomogram of quantum sy...
