# Quantum logic gates for superconducting resonator qudits

@article{Strauch2011QuantumLG, title={Quantum logic gates for superconducting resonator qudits}, author={Frederick W. Strauch}, journal={Physical Review A}, year={2011}, volume={84}, pages={052313} }

We study quantum information processing using superpositions of Fock states in superconducting resonators as quantum d-level systems (qudits). A universal set of single and coupled logic gates is theoretically proposed for resonators coupled by superconducting circuits of Josephson junctions. These gates use experimentally demonstrated interactions and provide an attractive route to quantum information processing using harmonic oscillator modes.
