QuTech researchers, collaborating with Fujitsu and Element Six, have achieved a significant quantum computing milestone by demonstrating diamond spin-based quantum gates with error rates below 0.1%—satisfying a critical threshold for quantum error correction and bringing us one step closer to scalable quantum computation.
Lower cooling requirements, longer operating times, lower error rates: Quantum computers based on spin photons and diamond promise significant advantages over competing quantum computing technologies. The consortium of the BMBF project SPINNING coordinated by Fraunhofer […]
A paper has solved a major hurdle facing researchers working with diamond by creating a novel way of bonding diamonds directly to materials that integrate easily with either quantum or conventional electronics. With this technique, […]
Quantum coherence in diamond-based NV centers, crucial for quantum computing applications, faces limitations from decoherence effects. This study examines how nitrogen impurities (P1 centers) impact NV-spin coherence using cluster correlation expansion and density functional theory. Results show T2 varies linearly with P1 concentrations (log scale, -1.06 slope), matching experimental data. The Jahn-Teller effect and hyperfine interactions significantly influence decoherence dynamics. These findings establish theoretical T2 limits across P1 densities, guiding material optimization for quantum devices.
