1.Product Overview

TNU1CTU is a dedicated classical optical interconnect research and experimental board designed for prototype development and laboratory research of quantum computing systems on the OSN 9800 series optical transmission platform.This product aims to provide high-performance and highly flexible control signal distribution, state reading data feedback, and system synchronization solutions for medium to large-scale (tens to hundreds of qubits) quantum computing prototypes.It addresses the practical engineering challenges in quantum laboratory environments by deeply integrating advanced optical communication technology with quantum control system requirements, providing a programmable, observable, and optimizable classical network experimental platform for quantum computing researchers and engineers to accelerate the evolution of quantum prototypes towards practical systems.

2.Core positioning and engineering challenges to be solved

Low noise and low jitter optical distribution of quantum control signals

Provide high fidelity electro-optical conversion and transmission channels for microwave or laser controlled pulses required for quantum bits such as superconductors and ion traps, minimizing additional noise and timing jitter introduced by the transmission link.

Resolve signal attenuation, crosstalk, and electromagnetic interference issues caused by long cable transmission in laboratory environments.

Real time transmission and processing of high bandwidth measurement data

Provide a high linearity and high bandwidth fiber optic transmission path for high-speed analog or digital signals generated by quantum state reading, such as resonant cavity frequency response and photon counting.

Classic data processing units (such as FPGA, CPU) that support low latency transmission of raw measurement data to room temperature for real-time feedback and control.

Synchronization and timing management of multi-channel systems

Provide high-precision multi-channel signal synchronization output capability for complex multi-channel quantum control systems (such as those that require simultaneous operation of multiple qubits).

Support synchronization with external master clocks (such as atomic clocks, GPS tame clocks) to ensure a unified time reference for the entire experimental system.

Flexible adaptation to diverse quantum hardware and experimental protocols

The design has high configurability and programmability, and can adapt to the special requirements of different quantum computing systems (superconductivity, ion traps, photons, etc.)and different experimental protocols for control waveforms, timing, and data processing methods.
