2.Core positioning and core challenges to be addressed

Exploration of the Performance Limits of Quantum Bit Controlled Networks

Research the high fidelity and high-precision distribution capability of microwave/laser control pulses required for mainstream quantum computing routes such as superconductivity and ion traps in complex optical networks.

Explore how to achieve scaled expansion of control channels while maintaining signal integrity through advanced optical network architectures such as wavelength division multiplexing and space division multiplexing as the quantum bit scale grows exponentially.

Femtosecond level global synchronization and extremely low jitter transmission

Quantum computing operations require strict time alignment of all control signals and measurement signals (typically requiring sub nanosecond to picosecond synchronization, and future femtosecond synchronization).

This platform aims to study how to achieve femtosecond level time synchronization distribution and extremely low jitter (<10 fs RMS) signal transmission across cabinets and computing modules in a distributed optical network environment.

High speed and low-noise feedback of quantum state reading data

The analog or digital signals generated by quantum bit measurement need to be collected at high speed and low noise and transmitted back to the classical processing unit.

Platform research aims to achieve a high bandwidth and high signal-to-noise ratio measurement data optical transmission scheme in a quantum computing laboratory environment with strong electromagnetic interference.
