Efficient amplification of superpositions of coherent states using input states with different parities
Changhun Oh, Hyunseok Jeong
We investigate an experimentally feasible scheme for amplification of superpositions of coherent states (SCSs) in light fields. This scheme mixes two input SCSs at a 50:50 beam spl…
Optimal Gaussian measurements for phase estimation in single-mode Gaussian metrology
Changhun Oh, Changhyoup Lee, Carsten Rockstuhl +4
The central issue in quantum parameter estimation is to find out the optimal measurement setup that leads to the ultimate lower bound of an estimation error. We address here a ques…
Bayesian error regions in quantum estimation II: region accuracy and adaptive methods
Changhun Oh, Yong Siah Teo, Hyunseok Jeong
Bayesian error analysis paves the way to the construction of credible and plausible error regions for a point estimator obtained from a given dataset. We introduce the concept of r…
Bayesian error regions in quantum estimation I: analytical reasonings
Yong Siah Teo, Changhun Oh, Hyunseok Jeong
Results concerning the construction of quantum Bayesian error regions as a means to certify the quality of parameter point estimators have been reported in recent years. This task…
