- Abstract: Enabling scalable and energy-efficient control of spin defects in solid-state
media is desirable for realizing transformative quantum information
technologies. Exploiting voltage-controlled magnetic anisotropy, we report
coherent manipulation of nitrogen-vacancy (NV) centers by the spatially
confined magnetic stray fields produced by a proximate resonant magnetic tunnel
junction (MTJ). Remarkably, the coherent coupling between NV centers and the
MTJ can be systematically controlled by a DC bias voltage, allowing for
appreciable electrical tunability in the presented hybrid system. In comparison
with current state-of-the-art techniques, the demonstrated NV-based quantum
operational platform exhibits significant advantages in scalability, device
compatibility, and energy-efficiency, further expanding the role of NV centers
in a broad range of quantum computing, sensing, and communications
applications.

Hybrid quantum systems (HQSs) of localized nitrogen-vacancy (NV) centers in diamond and delocalized magnon modes have attracted significant attention.
Here, we experimentally determine the magnon-mediated NV-NV coupling from the magnon-induced self-energy of NV centers.
Our results are quantitatively consistent with a model in which the NV center is coupled to magnons by dipolar interactions.

Electromagnetically induced transparency (EIT) is a phenomenon that can provide strong and robust interfacing between optical signals and quantum coherence of electronic spins.
We show that EIT can be established with high visibility also in this material platform upon careful design of the measurement geometry.
Our work provides an understanding of EIT in multi-level systems with significant inhomogeneities, and our considerations are valid for a wide array of defects in semiconductors.
