Quantum state estimation with nuisance parameters
Jun Suzuki, Yuxiang Yang, Masahito Hayashi
In parameter estimation, nuisance parameters refer to parameters that are not of interest but nevertheless affect the precision of estimating other parameters of interest. For inst…
Uncertainty relation for the position of an electron in a uniform magnetic field from quantum estimation theory
Shin Funada, Jun Suzuki
We investigate the uncertainty relation for estimating the position of one electron in a uniform magnetic field in the framework of the quantum estimation theory. Two kinds of mome…
Nuisance parameter problem in quantum estimation theory: General formulation and qubit examples
Jun Suzuki
In this paper, we analyze quantum-state estimation problems when some of the parameters are of no interest to be estimated. In classical statistics, these irrelevant parameters are…
User-specified random sampling of quantum channels and its applications
Jun Yan Sim, Jun Suzuki, Berthold-Georg Englert +1
Random samples of quantum channels have many applications in quantum information processing tasks. Due to the Choi--Jamiołkowski isomorphism, there is a well-known correspondence b…
Quantum process tomography via optimal design of experiments
Yonatan Gazit, Hui Khoon Ng, Jun Suzuki
Quantum process tomography --- a primitive in many quantum information processing tasks --- can be cast within the framework of the theory of design of experiment (DoE), a branch o…
