QUANTUM OPTO-MECHANICS WITH ATOMS AND NANOSTRUCTURED DIAMOND: QOMAND
Abstract
Title: Quantum Opto-Mechanics with Atoms and Nanostructured Diamond: QOMANDObjective:The overarching goal of this MURI program is the realization of hybrid systems involving optomechanical devices that operate in the nonlinear quantum regime and which are strongly coupled to isolated qubits and telecom-wavelength photons. These systems will be used to study fundamental scientific questions regarding the key building blocks for integrated quantum networks, communication, information processing, and a new generation of quantum sensors.Approach:The program seeks to leverage several recently-developed capabilities, including: highly sophisticated planar optomechanical devices in silicon-based materials; new nanofabrication techniques for single-crystal diamond; breakthroughs in 2D material research (e.g. graphene); the efficient coupling of chip-based optomechanical devices with single-mode telecom fibers; and the coupling of these devices to well-established qubits such as nitrogen-vacancy (NV) and silicon-vacancy (SiV) centers in diamond and cold trapped atoms. These capabilities will be used to map nonclassical qubit states and quantum states of light onto phonons (and vice-versa) and will enable fundamentally new ways to prepare, control, and read out the states of quantum systems. The MURI team will investigate previously unexplored mechanisms of qubit-optomechancal interaction and new forms of optomechanical coupling to atomically thin materials. This program will push the state of the art in a number of different disciplines, including quantum science and technology, nanoscale optomechanics, materials science, and nanofabrication.Statement of Work:The MURI program is organized into four complementary thrust areas that will address four grand goals of quantum science and technology and answer the key scientific and technological questions associated with these goals. These grand goals are:~ -Quantum nonlinear regime of optomechanics~ -Quantum control of atomic motion in nanophotonic systems~ -Spin-phonon-photon quantum transducers and phonon networks~ -Optomechanical interaction in atomically thin materialsThe team will address important scientific questions and develop new paradigms for the following research avenues:~ -Multi-node quantum networks, both on chip and fiber coupled, including memory, quantum level nonlinearity, and operation at technologically desirable wavelength and bandwidth;~ -Quantum sensing, including electromagnetic field detection, motion/ displacement sensing beyond the standard quantum limit, force and strain sensing;~ -Quantum optical logic with nano-scale structures for metrology, quantum communication, and computation;~ -Efficient sources of nonclassical light for the synthesis and detection of ~arbitrary~ quantum states of light;ONR Relevance:The devices developed in this program will mostly be chip-based, and will integrate quantum functionality in materials such as silicon and diamond with telecom wavelength fiber optics. They may find applications in navigation, timekeeping, magnetometry, and practical systems for quantum information processing and communication (including quantum repeaters, and efficient sources of nonclassical light). This program will advance the state-of-the-art in nanofabrication of single-crystal diamond, which may find application in devices beyond those considered as part of this proposal. This program will also be used to train students and postdocs at leading US universities in state-of-the-art techniques in quantum information science and engineering. We anticipate that such highly trained specialists will be of considerable value for future DoD research and development programs. The PIs have an excellent track record in attracting, educating and training top young people in the field, and in advancing their careers in industrial, government, and academic settings.
