The Cornell project, called “Hybrid Quantum Magnonics for Transduction and Sensing,” received $1.8 million of the funding and is led by Greg Fuchs, associate professor of applied and engineering physics in Cornell’s School of Applied and Engineering Physics (Cornell Engineering).
The research aims to make advances on one of the fundamental challenges of solid-state quantum technologies: networking quantum processors together to exchange information, according to an Aug. 16 news release on the Cornell website.
The project will also focus on quantum-enhanced sensing, by using magnons — the magnetic excitations in ultra-low damping materials — to connect superconducting circuits to individual quantum bits. By combining desirable properties from different quantum systems, the hybrid systems will create new opportunities for enhanced quantum functionality, including the control of large-scale quantum states, new interconnects for solid-state quantum bits, and the ability to control the direction of quantum information flow.
“I’m excited to push magnetic materials into the quantum limit to enable new ways to make quantum devices,” Fuchs said in the release. “The project is fundamental, but the opportunity is to take advantage of the fact that magnetic materials are nonreciprocal, meaning they can enforce ‘one-way’ interactions. That is currently difficult in quantum systems.”
Research collaborators include Dan Ralph, a physics professor in Cornell’s College of Arts and Sciences; Michael Flatté, professor of physics and astronomy at the University of Iowa; and Ezekiel Johnston-Halperin, professor of physics at Ohio State University.
The Cornell project “Planar System for Quantum Information” received $3.6 million and is led by Jie Shan, professor of applied and engineering physics at Cornell Engineering.
Shan and her research partners will focus on developing moiré materials for quantum simulation, which are formed by overlaying layers of 2D materials with a small twist angle or lattice mismatch. Electrons can tunnel between traps created by the moiré structure, presenting “unprecedented possibilities” for simulation of interacting quantum particles in a solid-state platform.
The project will also develop advanced methods for material synthesis and 2D assembly, such as bulk crystal growth using a flux-synthesis method and the creation of tailored 2D heterostructures with on-demand control of rotation angle using dry-transfer techniques.
Co-principal investigators include Kin Fai Mak, associate professor of physics in Cornell’s College of Arts and Sciences, as well as collaborators from Columbia University, the University of Texas at Austin, and the SLAC National Accelerator Laboratory, operated by Stanford University.
