Xianjing Zhou

Xianjing Zhou pioneered a fundamentally new solid-state quantum computing platform by realizing the world’s first single-electron qubit on solid neon. This breakthrough began with the first observation of strong coupling between a single electron and a single photon, marking a critical milestone toward practical quantum computing.

He demonstrated the exceptional performance of this new qubit system, which includes a 0.1 ms coherence time (the longest coherence time of a charge state), high-fidelity single-shot readout (98.1% without quantum parametric amplifier), high-fidelity single-qubit gate (99.97%), two-qubit coupling, and more.

Compared to other extensively studied qubits, this platform offers competitive performance while leveraging the pristine nature of solid neon to effectively suppress environmental noise. This makes it a promising candidate for building more stable and reliable quantum computers. 

This platform also holds great promise for quantum sensing and other quantum information applications. Since single-electron systems are highly sensitive to electromagnetic fields and external perturbations, they could serve as ultra-precise quantum sensors for detecting weak electric fields, magnetic fields, and mechanical vibrations. This opens potential applications in fundamental physics research, precision metrology, and material characterization. Additionally, the ultra-clean environment of solid neon makes it a strong candidate for quantum memory and quantum networking, further expanding its impact on the future of quantum technology.

Moving forward, Xianjing is committed to further advancing this novel quantum platform, exploring its full potential for quantum computing, quantum sensing, and quantum communication, and contributing to the next breakthroughs in quantum technology.
