Advancements in Ternary Quantum Information Processing: High-Fidelity Generation of Two-Qutrit Entangling Gates

Researchers at Lawrence Berkeley National Laboratory and the University of California, Berkeley have achieved a breakthrough in quantum computing by successfully entangling two qutrits, three-level quantum systems, with high fidelity. This advancement brings us closer to enabling ternary logic, which can encode more information than binary logic. The team used a microwave-activated entanglement technique and achieved gate fidelities significantly higher than previous works. Ternary quantum information processors have the potential to improve quantum simulation, error correction, and certain quantum algorithms and applications.
