Executive Summary
Section titled “Executive Summary”- Value Proposition: Identifies and characterizes a promising NV- center in MgO as a potential spin qubit for hybrid quantum technologies, leveraging MgO’s technological maturity.
- Specific Achievement: Demonstrated the NV- center’s stable triplet ground and excited states, enabling optical initialization and spin-dependent readout.
- Specific Achievement: Predicted key properties like absorption/emission energies, zero-field splitting (ZFS) tensor, and hyperfine interaction parameters for experimental identification.
- Specific Achievement: Analyzed the strong vibronic coupling of the NV- center with the MgO lattice and proposed design strategies to reduce it.
- Method: Utilized a high-throughput first-principles framework, advanced electronic structure methods (hybrid TDDFT, QDET), and the ADAQ software package.
- Potential Impact: Could enable hybrid classical-quantum applications, such as spintronic quantum sensors and single qubit gates, by combining spintronics, ferroelectrics, and quantum information science.
