Quantum Tomography of Pure States with Projective Measurements Distorted by Experimental Noise
Artur Czerwinski
The article undertakes the problem of pure state estimation from projective measurements based on photon counting. Two generic frames for qubit tomography are considered -- one com…
Open quantum systems integrable by partial commutativity
Artur Czerwinski
The article provides a framework to solve linear differential equations based on partial commutativity which is introduced by means of the Fedorov theorem. The framework is applied…
Phase estimation of time-bin qudits by time-resolved single-photon counting
Artur Czerwinski, Karolina Sedziak-Kacprowicz, Piotr Kolenderski
We present a comprehensive framework for quantum state tomography (QST) of time-bin qudits sent through a fiber. Starting from basic assumptions, we define a positive-operator valu…
Quantum state tomography with informationally complete POVMs generated in the time domain
Artur Czerwinski
The article establishes a framework for dynamic generation of informationally complete POVMs in quantum state tomography. Assuming that the evolution of a quantum system is given b…
Tomography of time-bin quantum states using time-resolved detection
Karolina Sedziak-Kacprowicz, Artur Czerwinski, Piotr Kolenderski
We present a method for measuring quantum states encoded in the temporal modes of photons. The basis for the multilevel quantum states is defined by the use of modes propagating in…
Dynamic state reconstruction of quantum systems subject to pure decoherence
Artur Czerwinski
The article introduces efficient quantum state tomography schemes for qutrits and entangled qubits subject to pure decoherence. We implement the dynamic state reconstruction method…
