Indirect Cooling of Weakly Coupled Trapped-Ion Mechanical Oscillators
Pan-Yu Hou, Jenny J. Wu, Stephen D. Erickson +6
Cooling the motion of trapped ions to near the quantum ground state is crucial for many applications in quantum information processing and quantum metrology. However, certain motio…
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 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 (…
