Optimal quantum multi-parameter estimation and application to dipole- and exchange-coupled qubits
Kevin C. Young, Mohan Sarovar, Robert Kosut +1
We consider the problem of quantum multi-parameter estimation with experimental constraints and formulate the solution in terms of a convex optimization. Specifically, we outline a…
Quantum Process Tomography via L1-norm Minimization
Robert L. Kosut
For an initially well designed but imperfect quantum information system, the process matrix is almost sparse in an appropriate basis. Existing theory and associated computational m…
Channel-Optimized Quantum Error Correction
Soraya Taghavi, Robert L. Kosut, Daniel A. Lidar
We develop a theory for finding quantum error correction (QEC) procedures which are optimized for given noise channels. Our theory accounts for uncertainties in the noise channel,…
Quantum Metrology Subject to Instrumentation Constraints
Robert L. Kosut
Maximizing the precision in estimating parameters in a quantum system subject to instrumentation constraints is cast as a convex optimization problem. We account for prior knowledg…
