Abstract

The quantum state tomography is an essential component in the development of quantum technologies. It is a representation of polarization state which can be used to know the characterization of small particle called photon in the nanoscale. In this research, photon number has been measured in order to create the states tomography. Optical devices and quantum-mechanical approaches were used to accomplish the image of quantum state tomography. Due to a single qubit state density matrix can be represented by Stokes parameters, so there are four set-ups to measure the Stokes parameters for each sample. The density matrix in this work is used because the pure state only happen in theoretical idea. And in the real experiment, It always shows a mixed state. The density matrix will represent seven samples in this work. The samples of tomography measurements consist of horizontal state, vertical state, diagonal state, anti-diagonal state, right-circular state, left-circular state and the tomography of laser IR 808nm. In this work, state tomography is shown by 2x2 density matrix. This research also shows the fidelities between theory and experiment result. And it shows the good agreement. From this research, the state of laser beam has known. The laser that used is showing a vertical state with fidelity F=97,34%.
