DURIP: Enhancing Electromagnetic Wave Coupling to Topological Quantum States in Low Dimensional Materials
Abstract
We propose to develop instrumentation to enable microwave/THz/optical control of non-abeliananyons and entangled photons in quantumdevices made of low-dimensional materials. One of the majortechnological challenges for the effective operation of quantum computers is the control and regulationof qubit decoherence. In this project, we plan to construct an instrument that can combine microwave,THz and optical control of emergent quantum states realized in 2D quantum heterostructures by a uniquecombination of electromagneticwave coupling to quantum devices in the radio frequency (RF),microwave (MW), THz and optical frequency range. We will use this instrument to demonstrate themanipulation and characterization of entangled quantum states in low-dimensional materials whereemergent condensation of excitons can be realized. The PI, Philip Kim, is a leader in the science andtechnology of two-dimensional (2D) and quantum materials. Much of the PI s research has beensupported by ONR and otherDoD agencies. The instrument will also offer exciting opportunities for thedevelopment of novel quantum electronic and optoelectronic devices based on 2D materials andgraphene nanoelectronic structures.Specifically, the proposed instrument development will enhance three DoD-funded researchprojects on 2D quantum materials for electronic and optoelectronic device applications. Since theentangled quantum states can often be manipulated by electromagnetic waves with resonant energyscales of the system, the new instrument will enhance our current ONR-funded research projects byproviding broadband access to electromagnetic waves via a specially designed port. These projectsinclude Non-Abelian Anyon Braiding in Corbino Topological Josephson Junctions (N00014-24-1-2081,Program Manager: Dr. Lennart (Dan) Gunlycke), Topological Spin Qubits Based on GrapheneNanoribbons (N0014-21-1-2537, Program Manager: Dr. Lennart (Dan) Gunlycke); and QuantumEngineered van der Waals Heterostructures for Topological Electronic Structures towards Novel DeviceApplications (N00014-18-1-2877, Program Manager: Dr. Jean-Luc Cambier); and ExtraordinaryElectronic Switching of Thermal Transport (N00014-1-12377, Program Manager: Dr. Mark Spector).The microwave/THz/optical access in low temperature measurement system provided by the magnetoopticalcryostat will create a new research opportunity in our current ONR-funded research to provide awide range of electromagnetic wave coupling to the quantum states for new characterization andcoherent manipulation. The instrument will also have a major impact on the ARO-funded research onproviding new characterization capabilities for entangled photon pairs from a TMD-based light emittingdiode using correlated electron holes in superconducting proximitized TMD semiconductors.By enabling electromagnetic wave coupling, we will novel device applications such as low-power,high-speed electronics. These advances are critical to miniaturized electronics, a major focus ofONRand DoD. Our interdisciplinary approach provides excellent training opportunities for graduate studentsand postdoctoral fellows in the fields of RF, microwave, mm-wave, THz, optics, cryogenics, andquantum device engineering, providing pathways to employment with industry and DoD partners. Thebroadapplicability of these devices benefits diverse research efforts in the broader community.
