Dissipative preparation of W states in trapped ion systems
Daniel C. Cole, Jenny J. Wu, Stephen D. Erickson +4
We present protocols for dissipative entanglement of three trapped-ion qubits and discuss a scheme that uses sympathetic cooling as the dissipation mechanism. This scheme relies on…
Quantum harmonic oscillator spectrum analyzers
Jonas Keller, Pan-Yu Hou, Katherine C. McCormick +5
Characterization and suppression of noise are essential for the control of harmonic oscillators in the quantum regime. We measure the noise spectrum of a quantum harmonic oscillato…
Ion transport and reordering in a two-dimensional trap array
Y. Wan, R. Jördens, S. D. Erickson +7
Scaling quantum information processors is a challenging task, requiring manipulation of a large number of qubits with high fidelity and a high degree of connectivity. For trapped i…
Quantum logic spectroscopy with ions in thermal motion
D. Kienzler, Y. Wan, S. D. Erickson +4
A mixed-species geometric phase gate has been proposed for implementing quantum logic spectroscopy on trapped ions that combines probe and information transfer from the spectroscop…
Quantum gate teleportation between separated qubits in a trapped-ion processor
Yong Wan, Daniel Kienzler, Stephen D. Erickson +9
Large-scale quantum computers will require quantum gate operations between widely separated qubits. A method for implementing such operations, known as quantum gate teleportation (…
