Abstract: Brian Anderson

Quantum systems with a Hilbert space dimension greater than two (qudits) provide an alternative to qubits as carriers of quantum information, and may prove advantageous for quantum information tasks if good laboratory tools for qudit manipulation and readout can be developed. We have implemented a protocol for arbitrary unitary transformations (qudit manipulation) and quantum state tomography (qudit readout) in the 16 dimensional hyperfine ground manifold of Cesium 133 atoms. Our version of quantum state tomography uses our qudit control scheme, so the process of control and measurement are interrelated. I will discuss the theory and experiment behind these protocols that have been developed over the past several years.
