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…
Experimental speedup of quantum dynamics through squeezing
S. C. Burd, H. M. Knaack, R. Srinivas +9
We show experimentally that a broad class of interactions involving quantum harmonic oscillators can be made stronger (amplified) using a unitary squeezing protocol. While our demo…
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{…
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…
