Center for Molecular Quantum Transduction (CMQT)

Project: Research project

Project Details


The mission of the CMQT is to develop the fundamental scientific understanding
needed to carry out quantum-to-quantum transduction through a bottom up synthetic approach which imparts atomistic precision to quantum systems. The CMQT has assembled an interdisciplinary team of physicists, chemists, and materials scientists. with the individual expertise and collective breadth to bridge the knowledge gaps in this emerging field. CMQT goals are embodied in three cross-cutting Thrusts with closely integrated approaches and team
Thrust 1. Localized Molecular Quantum-to-Quantum Transduction (co-Leaders: Fuchs and Freedman). The goal of this Thrust is to develop new mechanisms and strategies to coherently couple localized molecular degrees of freedom, i.e. the various pairwise interactions between photons, excitons, magnons, phonons, spins, and charges, at the level of single molecules, and thus lay the foundation for molecular quantum-to-quantum transduction.
Thrust 2. Distributed Molecular Quantum-to-Quantum Transduction (co-Leaders:
Johnston-Halperin and Long). The goal of this Thrust is to demonstrate quantum transduction within distributed molecular quantum systems, which will bridge the length scales of single molecules with those of conventional solid-state quantum systems.
Thrust 3. Multi-scale Molecular Quantum-to-Quantum Transduction (co-Leaders:
Goldsmith and Weiss). The goal of this Thrust is to use the combination of flying qubits (photons) and molecular degrees of freedom to achieve quantum transduction over multiple length scales within hierarchical quantum systems.
Description: Designer molecular qubits with long coherence times and tunable interactions will enable quantum state transduction between molecular quantum states as well as quantum measurement at the level of single molecules. We will explore synthesis and measurements that leverage atomic precision to enable quantum transduction through local interactions. We will explore quantum transduction in ensembles of tailored molecular qubits that interact via spinmagnon
coupling to delocalized, highly coherent, magnon modes in molecule-based magnetic thin films. Incorporating molecular systems into photonic structures will demonstrate coherence transfer between multiple molecular degrees of freedom and between these degrees of freedom and photons, including producing heralded photons necessary to probe quantum aspects of natural and artificial photosynthesis.
