High-fidelity two-qubit gates in quantum computers are often hampered by fluctuating
experimental parameters. The effects of time-varying parameter fluctuations lead to coherent …

Describing the thermodynamic properties of quantum systems far from equilibrium is
challenging, in particular when the system is strongly coupled to its environment, or when …

Bosonic modes are prevalent in all aspects of quantum information processing. However,
existing tools for characterizing the quality, stability, and noise properties of bosonic modes …

Trapped atomic ion crystals are a leading platform for quantum simulations of spin systems,
with programmable and long-range spin-spin interactions mediated by excitations of …

Two-qubit gates in trapped-ion quantum computers are generated by applying spin-
dependent forces that temporarily entangle the internal state of the ion with its motion. Laser …

Spectroscopy is one of the most accurate probes of the molecular world. However,
predicting molecular spectra accurately is computationally difficult because of the presence …

High-quality control is a fundamental requirement for quantum computation, but practically it
is often hampered by the presence of various types of noises, which can be static or time …

Electric-field noise stemming from surface adsorption of atoms serves as the main factor of
anomalous motional heating and decoherence for trapped ions confined in harmonic …

In quantum logic spectroscopy (QLS), one species of trapped ion is used as a sensor to
detect the state of an otherwise inaccessible ion species. This extends precision …

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 …
