Analogy between optimal spin estimation and interferometry
Z. Hradil, M. Dusek
Scheme for optimal spin state estimation is considered in analogy with phase detection in interferometry. Recently reported coherent measurements yielding the average fidelity (N+1…
Reconstruction of the spin state
Z. Hradil, J. Summhammer, G. Badurek +1
System of 1/2 spin particles is observed repeatedly using Stern-Gerlach apparatuses with rotated orientations. Synthesis of such non-commuting observables is analyzed using maximum…
Quantum theory of incompatible observations
Z. Hradil, J. Summhammer
Maximum likelihood principle is shown to be the best measure for relating the experimental data with the predictions of quantum theory.
Quantum tomography as normalization of incompatible observations
Z. Hradil, J. Summhammer, H. Rauch
Quantum states are successfully reconstructed using the maximum likelihood estimation on the subspace where the measured projectors reproduce the identity operator. Reconstruction…
Entropy of phase measurement: Quantum phase via quadrature measurement
Zdeněk Hradil, Robert Myška, Tomáš Opatrný +1
The content of phase information of an arbitrary phase--sensitive measurement is evaluated using the maximum likelihood estimation. The phase distribution is characterized by the r…
Quantization of electromagnetic field in inhomogeneous dispersive dielectrics
Zdenek Hradil
Canonical quantization of electromagnetic field inside the time--spatially dispersive inhomogeneous dielectrics is presented. Interacting electromagnetic and matter excitation fiel…
