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…
Quantum control using sequences of simple control pulses
S. G. Schirmer, A. D. Greentree, V. Ramakrishna +1
Structured decompositions of a desired unitary operator are employed to derive control schemes that achieve certain control objectives for finite-level quantum systems using only s…
Control of a Coupled Two Spin System Without Hard Pulses
V. Ramakrishna, R. J. Ober, K. L. Flores +1
Constructive methods for controlling a coupled, two spin system via bounded amplitude, piecewise sinusoidal fields are provided. The fields are incident at the alrmor frequencies a…
