Abstract |
|
|
| We develop a practical quantum tomography protocol and implement measurements
of pure states of ququarts realized with polarization states of photon pairs (biphotons).
The method is based on an optimal choice of the measuring scheme’s parameters that
provides better quality of reconstruction for the fixed set of statistical data. A high
accuracy of the state reconstruction (above 0.99) indicates that developed methodology
is adequate. |
