Abstract: The disclosure is directed to devices, systems, and methods for a generation of a decoherence-protected subspace in a quantum system. The decoherence-protected subspace provides the quantum system with reduced sensitivity to environmental magnetic, electric, and thermal noises. Quantum information operation based on the quantum system can be performed while this decoherence-protected subspace is maintained.

Abstract: The disclosure is directed to devices, systems, and methods for performing quantum state-mediated microwave-to-optical energy conversion. Such quantum state-mediated energy conversion may be achieved via coherent interactions between an optical excitation and microwave electric field mediated by various quantum states in a defect embedded in a crystalline lattice. Such energy conversion enables coherent electro-optical modulation of optical emission from the defect, microwave-optical transduction, optical detection of microwave, and optical frequency mixing in the optical emission from the defect. The optical emission from the defect maintains and carries quantum coherence in the defect. Such devices and methods may be applied in quantum information processing systems.
