In collaboration with the Australian National University, IonQ has achieved a significant milestone in quantum computing by developing faster, higher-fidelity, mixed-species quantum gates using trapped-ion technology. This advancement, announced in College Park, MD, demonstrates a novel approach to achieving megahertz-speed two-qubit gates between different atomic species, reducing errors and improving scalability for large-scale quantum networks.
“In addition to being an important milestone for quantum computing, achieving high-speed mixed-species quantum gates is also a crucial step toward scalable and modular quantum networks,”“This research paves the way for architectures that can more efficiently interconnect and process information.”

The research introduces ultrafast state-dependent kicks (SDKs) from nanosecond laser pulses, enabling more efficient entanglement and quantum information transfer, which brings practical applications of quantum computing closer to reality.
The significance of ultrafast state-dependent kicks (SDKs) in IonQ’s quantum gate technology is their ability to precisely control individual qubits. SDKs apply tailored pulses to ions based on their quantum states, which helps mitigate errors and improve the fidelity of quantum operations. This technique is particularly important for scaling up ion trap quantum computers while maintaining high performance.
