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…
Coherent coupling and non-destructive measurement of trapped-ion mechanical oscillators
Pan-Yu Hou, Jenny J. Wu, Stephen D. Erickson +10
Precise quantum control and measurement of several harmonic oscillators, such as the modes of the electromagnetic field in a cavity or of mechanical motion, are key for their use a…
High-fidelity indirect readout of trapped-ion hyperfine qubits
Stephen D. Erickson, Jenny J. Wu, Pan-Yu Hou +8
We propose and demonstrate a protocol for high-fidelity indirect readout of trapped ion hyperfine qubits, where the state of a qubit ion is mapped to a $^{25}\text{…
Resource-efficient dissipative entanglement of two trapped-ion qubits
Daniel C. Cole, Stephen D. Erickson, Giorgio Zarantonello +7
We demonstrate a simplified method for dissipative generation of an entangled state of two trapped-ion qubits. Our implementation produces its target state faster and with higher f…
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 (…
