Major development successes in diamond spin photon quantum computers Consortium presents interim results of the BMBF project SPINNING .
Quantum computers based on spin photons and diamond promise significant advantages over competing quantum computing technologies.
For the first time, the project team successfully demonstrated entanglement of two registers of six qubits each over a distance of 20 m and achieved a high mean fidelity .
SPINNING outperforms SSJ quantum computers based on superconducting Josephson junctions.
With an error rate of < 0.5% , the spin-photon-based quantum computer comprising twelve qubits to date achieves the same result in the one -qubit gate as the prominent SJJ models Eagle ( 127 qubits) and Heron ( 154 qubits), in terms of coherence time.
