THIS GRANT IS A CONTINUATION OF N000141510048 Transcribing Quantum Information Using Quantum Dynamics of Coherent Materials
Abstract
Quantum information science stands to benefit immensely from real-world implementation ofsimple quantum algorithms at the device level. We will create a new blueprint for quantuminformation science by designing and synthesizing polymeric materials decorated withchromophores that support coherent relaxation dynamics, and examining how Laguerre-Gaussmodes are processed by the relaxation dynamics. By exploiting the analogy to coherentrelaxation dynamics evident in photosynthetic systems, these materials will permit directdetection of the quantum state of the incident photon. We will create theoretical models both tofeedback into the design process and to provide an interface to quantum information science.Two dimensional electronic spectroscopy will be used to characterize the coherent dynamics andrelaxation pathways within the functionalized polymers. The relaxation dynamics within thematerial can be customized and programmed for specific applications. The goal of this project isto create new materials for quantum information science that can exploit information channelsbeyond the ~classical~ regime without attempting to build a universal quantum computer.This project exploits excitations in semi-ordered supermolecular arrays of coupledchromophores attached to polymers; excitations in this material will delocalize across manychromophores, allowing different relaxation paths to interfere and be resolved. This intermediateregime presents a fascinating compromise between semiconductor systems, in which excitonlocalization due to disorder prohibits chemical control of dynamics, and molecular excited stateswhere coupling between molecules is random. With our proposed polymer systems, we haveenough chemical control to manipulate the structure, coupling, and detuning amongstchromophores while still exploiting some aspects of solid state physics that arise from coherentdelocalization of excited states. If successful, this effort will generate materials for opticalundersea communication, ultrasensitive detection, and quantum encryption.
