Encoding a qubit into multilevel subspaces
Matthew Grace, Constantin Brif, Herschel Rabitz +3
We present a formalism for encoding the logical basis of a qubit into subspaces of multiple physical levels. The need for this multilevel encoding arises naturally in situations wh…
Optimal Experiment Design for Quantum State and Process Tomography and Hamiltonian Parameter Estimation
Robert Kosut, Ian A. Walmsley, Herschel Rabitz
A number of problems in quantum state and system identification are addressed. Specifically, it is shown that the maximum likelihood estimation (MLE) approach, already known to app…
Quantum State Detector Design: Optimal Worst-Case a posteriori Performance
Robert L. Kosut, Ian Walmsley, Yonina Eldar +1
The problem addressed is to design a detector which is maximally sensitive to specific quantum states. Here we concentrate on quantum state detection using the worst-case a posteri…
