EQI Research Areas
EQI supports a diverse array of research efforts at Caltech, the University of California, Santa Barbara, and the University of California, Irvine, with an emphasis on projects that require interdisciplinary collaboration. Below is a partial list of research projects that have received funding from EQI grants. Further details can be obtained from the EQI school websites at:
High Fidelity Trapped Ion Qubit
High Fidelity Qubit Operations with Trapped Radium Ions
PI: Andrew Jayich UCSB
The Jayich group is developing the radium ion as a resource for quantum sensing and optical clocks. With radium, the group is addressing open questions in particle physics and cosmology. The group is developing optical clocks with radium that are promising for their compatibility with integrated photonic solutions, and hence are promising for transportable optical clocks.
PI: William Evans UC Irvine
The Evans group synthesizes new classes of molecular rare-earth metal complexes with the goal of finding new properties and new opportunities in quantum science. The group has made new classes of single-molecule magnets as well as new types of molecular qubits.
Quantum Interference in Topological Insulator/Superconductor Platform
PIs: Susanne Stemmer and Leon Balents UCSB
This project aims to take this approach a major step further by employing a unique and substantially advanced materials platform.
Hybrid Silicon-Nitride Superfluid-Helium Optomechanics
PI: Dirk Bouwmeester UCSB
This project proposes to combine the best of two worlds by covering an on-chip ultra-low loss photonic waveguide with superfluid Helium, which is the ultimate dissipation-free phonon medium.
Quantum Dynamics and Curved Spacetime
PI: David Weld UCSB
The goals of this project are to demonstrate the emergence of black-hole and white-hole event horizons in strongly-driven cavities and measure the dependence of fixpoint dynamics on drive parameters.
Studying Properties of Rare-Earth Quantum Magnets
PI: Sasha Chernyshev UC Irvine
The Chernyshev group focuses on theoretical studies of the rare-earth-based quantum magnets, in which strongly spin-orbit-coupled f-shells of the rare-earths facilitate anisotropic spin-spin interactions.
Electronic Structure Calculations
PI: Filipp Furche UC Irvine
The Furche research group’s research interests span quantum chemistry from formal electronic structure theory through software development to applications together with experimental groups.
Novel Quantum Sensors with Single Molecule Magnets
PI: Wilson Ho UC Irvine
The Ho group develops novel quantum sensors based on a single magnetic molecule attached to the tip of a scanning tunneling microscope (STM) to achieve atomic scale spatial resolution in magnetic sensing.
Exploring Quantum Spin Dynamics and Magnon Condensation in Rare Earth Magnetic Oxides.
PI: Ilya Krivorotov UC Irvine
The Krivorotov group studies relativistic quantum phenomena of spin-orbit torques in ferro- and ferrimagnetic rare earth oxides such as Y3Fe5O12 (yttrium iron garnet or YIG) and LaxSr1-xMnO3 (LSMO), as well as Bose-Einstein condensation of magnons in these materials.
Nanophotonic materials and devices to bridge quantum modalities
PI: Maxim Shcherbakov, UC Irvine
The Shcherbakov Nanophotonics Laboratory designs and implements nanostructured materials and devices, such as metamaterials and photonic integrated circuits, that enable transduction between domains, from photons to atomic qubits.
Quantum Acoustics in Diamond with SiV Center
PI: Ania Jayich UCSB
This project focuses on replacing NV centers with SiV centers so as to reach the high cooperativity regime.
Using Charge Carriers to Perturb the Candidate Spin Liquid State of NaRuO2
PI: Stephen Wilson UCSB
This project looks to explore the hypothesis that charge-doping a Mott insulator with a quantum spin liquid ground state results in an unconventional (potentially high-temperature) superconducting phase.
Investigating Topological Surfaces, Spin-Vibration Couplings, and Magnetic Molecules to Advance Robust Qubit Design for Quantum Computing.
PI: Ruqian Wu UC Irvine
The Wu group studies topological properties of SmB6 surface as well as rare earth and actinide atoms in oxide lattices for use as qubits. Theoretical analyses for the possibility of making exceedingly long coherence time of qubits with spin-vibration couplings was recently done.
