Title: **Adventures in Phase Space: Non-commuting coordinates meet quantum control and quantum error correction**  
Abstract: Rapid advances in quantum computation are placing new demands on our ability to precisely control bosonic modes (quantum harmonic oscillators) for the purposes of quantum communication, computation, simulation, and error-correction. It turns out that with only classical control signals, it is not possible to achieve universal quantum control of a harmonic oscillator. I will describe new techniques being developed for universal control of hybrid systems consisting of harmonic oscillators coupled to either anharmonic oscillators or two-level qubits. Our newfound ability to ‘sculpt’ arbitrary quantum distributions in phase space benefits from beautiful pictures that provide us with intuition for using the non-commutativity of the phase space coordinates (position and momentum) for designing efficient control sequences and instruction set architectures.
