Quantum tomography is a process that involves the reconstruction and characterization of a quantum state using a series of collected measurements. Over the past few years, many physicists have been trying to use this process ...
A certain amount of noise is inherent in any quantum system. For instance, when researchers want to read information from a quantum computer, which harnesses quantum mechanical phenomena to solve certain problems too complex ...
