Key suppliers of quantum research: application practice in scientific research
Blog Article
In the cutting-edge exploration of quantum research, optical component suppliers, with their professional products and customized services, have become a key force driving scientific research breakthroughs. Chongqing Smart and other enterprises, with acousto-optic devices and active/passive optical devices as their core, have deeply integrated into quantum research scenarios, providing technical support for fields such as quantum computing, quantum communication, and quantum precision measurement. The following is an analysis of their roles from the perspectives of practical cases and value creation.
Quantum computing: Precise control of optical qubits
(1) The core role of the sound and light modulator
In the experiment of optical quantum computing, it is necessary to precisely regulate the state of optical qubits. The acousto-optic modulator (AOM) provided by key suppliers in quantum research can rapidly modulate the frequency and intensity of lasers through radio frequency signals, achieving the "0" and "1" state switching of optical qubits. For instance, for the 1550nm band photonic quantum system, the customized AOM features an ultra-fast response time of ≤100ns and a high extinction ratio of ≥40dB. It can complete the logical operations of photonic qubits within nanoseconds, providing a stable optical control tool for the verification of quantum algorithms and the construction of quantum gates.
(2) Customized Solution Practice
The AOM customized for a certain quantum computing laboratory integrates a low-noise RF drive circuit and a highly stable acousto-optic medium. In the quantum state manipulation experiment of optical quantum chips, this AOM can stably output modulated signals with precise frequencies, increasing the fidelity of optical qubits to over 99%. Through collaborative optimization with the research team, the modulation frequency of AOM is matched with the optical coupling efficiency of the quantum chip, facilitating the laboratory to achieve the preparation of multi-bit optical quantum entangled states and promoting the advancement of quantum computing from theory to experimental verification.
Quantum communication: Reliable transmission and encryption of optical signals
(1) Application value of optical passive devices
Quantum communication relies on the stable transmission of single-photon and entangled photon pairs. The passive components such as low-loss optical fibers and high-isolation optical switches provided by the supplier ensure the integrity of quantum optical signals during long-distance transmission. In the quantum Key Distribution (QKD) system, low-loss optical fibers can control the transmission loss of single-photon signals to below 0.2dB/km. Combined with high-extinction ratio optical switches, it realizes the rapid switching and secure encryption of quantum channels, providing fundamental support for the construction of metropolitan and intercity quantum communication networks.
(2) Extreme Environment Adaptation cases
In the field experiments of quantum communication, the supplier customized waterproof and high-temperature resistant passive optical components to cope with high-temperature and high-humidity environments. The optical fiber connectors developed by it adopt a special sealing process, and the optical switch is equipped with an internal temperature compensation module to ensure the transmission stability of quantum optical signals in harsh environments. In a certain quantum communication research project, this type of device enabled the quantum key distribution distance to exceed 200 kilometers and controlled the bit error rate within 1%, verifying the feasibility of quantum communication in complex environments and accumulating experience for the practical deployment of quantum communication networks.
Quantum precision measurement: The guarantee of ultra-sensitive light detection
(1) Fine modulation of audio-visual devices
Quantum precision measurements (such as atomic clocks and gravitational wave detection) require ultra-stable laser light sources and fine light modulation. The supplier's acousto-optic modulator can precisely shift the laser frequency (such as 20-200 MHZ), and in combination with a highly stable RF source, the laser frequency stability is better than 10⁻¹⁵. In the atomic interferometer experiment, by modulating the laser frequency with AOM to control the stimulated transition and interference processes of atoms, the measurement accuracy of gravitational acceleration reached 10⁻⁹ g, providing a high-precision measurement tool for geological exploration and fundamental physics research.
(2) Technological innovation in collaborative scientific research
In collaboration with the quantum precision measurement research team, the supplier has developed a customized AOM for cold atom optical trap systems. The optimized AOM has lower insertion loss (<3dB) and higher frequency resolution, and can achieve fine power regulation and frequency scanning of atomic-cooled lasers. In the cold atomic clock experiment, this AOM helped the research team increase the frequency stability of the atomic clock to the 10⁻¹⁸ level, providing key technical support for the construction of a new generation of ultra-high-precision time reference, and promoting the development of quantum precision measurement towards a more microscopic and precise direction.
Value extension: From product supply to research partners
Key suppliers in quantum research are no longer confined to product delivery but are deeply involved in scientific research projects, collaborating with research teams on innovation from demand research to solution iteration. Accelerate the transformation of quantum scientific research achievements by sharing optical device R&D technologies and participating in the design of experimental plans. For instance, Chongqing Smart, with its patented technology and customized service capabilities, has provided an overall solution of "devices + technical support" for quantum laboratories in many domestic universities, enabling research teams to focus on exploring the essence of quantum physics and shortening the technology verification cycle.
Key suppliers in quantum research, taking professional optical components as a fulcrum, provide core support of "light control", "light transmission" and "light measurement" for scientific research breakthroughs in fields such as quantum computing, communication and precision measurement through customized products and collaborative innovation services. From basic research in the laboratory to practical technology verification, suppliers have deeply integrated into the quantum research ecosystem, becoming a key force in driving quantum technology from theory to application, and helping humanity unlock more mysteries of the quantum world.
