IonQ Demonstrates 1 kHz Memory-Enhanced Quantum Interconnect Connecting Trapped Ions and Diamond Color Centers
IonQ reported a memory-enhanced quantum interconnect that links a trapped ion qubit with a diamond-based quantum memory. The system operated at an entanglement rate above 1 kHz with high fidelity, which the company describes as a significant improvement over previous benchmarks. The work was carried out with Element Six and AWS.
IonQ could use this interface within two years to connect multiple trapped-ion modules through diamond color-center memories, creating small modular processors that share entanglement across physically separated traps.
