Informational completeness of continuous-variable measurements
D. Sych, J. Rehacek, Z. Hradil +2
We justify that homodyne tomography turns out to be informationally complete when the number of independent quadrature measurements is equal to the dimension of the density matrix…
Variations on the adiabatic invariance: the Lorentz pendulum
Luis L. Sanchez-Soto, J. Zoido
We analyze a very simple variant of the Lorentz pendulum, in which the length is varied exponentially, instead of uniformly, as it is assumed in the standard case. We establish qua…
Quantum polarization characterization and tomography
Jonas Soderholm, Gunnar Bjork, Andrei B. Klimov +2
We present a complete polarization characterization of any quantum state of two orthogonal polarization modes, and give a systematic measurement procedure to collect the necessary…
Complementarity and phases in SU(3)
H. de Guise, A. Vourdas, L. L. Sanchez-Soto
Phase operators and phase states are introduced for irreducible representations of the Lie algebra su(3) using a polar decomposition of ladder operators. In contradistinction with…
Symmetric discrete coherent states for n qubits
C. Munoz, A. B. Klimov, L. L. Sanchez-Soto
We put forward a method of constructing discrete coherent states for n qubits. After establishing appropriate displacement operators, the coherent states appear as displaced versio…
The transfer matrix: a geometrical perspective
L. L. Sanchez-Soto, J. J. Monzon, A. G. Barriuso +1
We present a comprehensive and self-contained discussion of the use of the transfer matrix to study propagation in one-dimensional lossless systems, including a variety of examples…
