In the high-tech field, quantum computing is hailed as the "next generation computing revolution." Unlike traditional electronic computing, quantum computers have extremely high requirements for each component in design and structure, with the performance of connectors (Connector) being particularly crucial. Today, we combine the product characteristics of the globally renowned brand Murata (Murata) to discuss whether domestically produced connectors can meet the application requirements of quantum computing interfaces.
One, advantages of Murata connectors in the high-precision electronics fieldMurata is one of the world's leading electronic component manufacturers, with profound technical accumulation in high-frequency communication, microwave connectivity, board-to-board signal transmission, and module integration. Its connector products are widely used in:
● Wireless communication module (Wi-Fi, 5G, Bluetooth)
Medical instruments and precision sensors
●Automotive electronics and industrial automation systems;
Microwave communication and radio frequency test equipment.
Murata's connector features mainly include:
Low contact resistance and stable high-frequency performance;
●Compact design, supporting high-density PCB layout;
Excellent mechanical life and vibration resistance.
Adaptable to precise welding and automatic assembly processes.
These technical foundations have also laid the groundwork for its potential applications in quantum computing, optical communication, and high-energy physics equipment.
Special Requirements for Quantum Computing InterfacesQuantum computers have a "core connection" that is different from ordinary circuit systems. The requirements for connectors are extremely strict in aspects such as control signals, low-temperature readout, and quantum bit coupling, mainly including:
High-temperature working capacity (usually in the millikelvin temperature range)
Connector materials must have an extremely low thermal expansion coefficient and thermal conductivity to avoid the instability of qubits.
High shielding and low noise performance
●The radio frequency connector requires an extremely high shielding ratio to prevent external electromagnetic interference from disrupting quantum states.
3. High-frequency and ultra-wideband transmission characteristics
The transmission of control and readout signals for quantum bits usually operates at GHz levels and requires extremely high impedance consistency.
4. Vacuum Compatibility and Low Outgassing Materials
Connectors for superconducting systems must be made of non-volatile, low-pollution materials.
Murata's technology in射频连接器和微波组件 is highly consistent with the above requirements. Its coaxial connector series maintains stable performance at GHz-level frequencies and is a common solution in scientific instruments and precision testing equipment.
Part Three: Opportunities and Challenges of Domestic Connectors in the Quantum Computing FieldCurrently, many domestic connector companies have started to layout the R&D in high-frequency, low-temperature, and quantum measurement and control interface directions, such as using gold-plated terminals, ceramic insulators, ultra-thin shells and other technologies to meet the requirements of high-precision signal transmission.
But compared with international brands like Murata, domestic connectors still face three challenges:
Insufficient data accumulation of low-temperature performance: Most domestic connectors have excellent performance at normal temperatures, but there is still a lack of reliability verification data below -200°C.
2. High-frequency consistency and microwave loss: The insertion loss and reflection characteristics of some models still need to be optimized in frequency bands above 20GHz.
Mass production consistency and miniaturization precision control: the precision processing and assembly technology still needs to be further improved to meet the requirements of quantum experimental systems for micro-size tolerances.
However, domestic manufacturers are also actively breaking through:
Develop terminal materials that are compatible with low-temperature copper alloys and high-purity coatings.
Optimize the RF structure to achieve better return loss performance.
Collaborate with research institutions to verify the reliability at low temperatures and electromagnetic compatibility.
This means that domestically produced connectors have the full potential to replace applications in quantum computing interfaces in the future.
Four, the integration path of Murata and domestic substitutionFrom the current trend, Murata's connectors still dominate the high-reliability field, while domestic manufacturers are accelerating towards the direction of "customized quantum interfaces." In the future, domestic substitution may take the following three paths:
Material and process localization: Adopting domestically produced LCP plastic, ceramic insulators, and gold-plated terminal materials.
Structural compatibility replacement: compatible with Murata's existing connection size and lock structure, achieving "plug and play" replacement.
3. Joint verification and certification cooperation: domestic manufacturers and research institutions jointly establish a low-temperature verification standard system, gradually obtaining recognition from laboratories and industrial projects.
This "technology benchmarking + scenario adaptation" approach is expected to allow domestic connectors to occupy a place in quantum computing interfaces.
The competition in quantum computing interfaces is both a clash of scientific frontiers and a contest of precision manufacturing processes. With its accumulation in high-frequency and high-reliability fields, Murata has set a technical benchmark for the connector industry. Meanwhile, domestic connector companies are rapidly rising, making significant progress in material, structural design, and automated assembly. It is predictable that within the next three to five years, domestically produced high-precision connectors are expected to enter the core supply chain of quantum computing interfaces.
