Quantum Communication Empowers All-in-One Computer Touch Screens: Reconstructing Data Security and Intelligent Decision-Making Systems in Smart Cities
In smart city construction, all-in-one computer touch screens are evolving from "information display terminals" to the "nerve centers of urban intelligent agents." By integrating display, computing, communication, and control functions, they connect key aspects of urban operations such as transportation, energy, and security. However, as the number of devices surpasses the tens of billions, traditional encryption systems face risks from quantum computing attacks, while data transmission delays and device heterogeneity have become bottlenecks limiting system efficiency. The integration of quantum communication with all-in-one computer touch screens is providing breakthrough solutions to these challenges.
Traditional IoT devices often rely on asymmetric encryption algorithms like RSA and ECC, whose security is based on the complexity of mathematical problems. However, Shor's algorithm on quantum computers can break these algorithms exponentially faster, posing a disruptive risk to existing encryption systems. Quantum Key Distribution (QKD) ensures end-to-end security in key generation, transmission, and verification through the quantum no-cloning theorem and measurement collapse principle:
Beijing-Shanghai Quantum Communication Trunk Line:
The University of Science and Technology of China (USTC) team achieved a 512-kilometer fiber-optic QKD network with a key distribution rate of 1.12 Mbps and a bit error rate below 1%, validating the feasibility of metropolitan-scale quantum-secure communication.
Quantum Teleportation (QT):
In smart healthcare scenarios, QT enables instantaneous and secure transmission of patient vital signs. For example, a top-tier hospital used quantum relay nodes to encrypt and transmit ICU device data to a cloud-based AI diagnostic platform, reducing latency from 500 ms in traditional solutions to under 20 ms.
All-in-one computer touch screens must handle millisecond-level response tasks such as traffic signal control and industrial equipment coordination. Quantum communication's entangled state transmission eliminates signal attenuation and retransmission delays in traditional communication:
Quantum Direct Communication (QDC):
A QDC prototype developed by Shanghai Jiao Tong University achieved 10 Gbps relay-free transmission over 10 kilometers of optical fiber with end-to-end latency below 100 μs, meeting real-time interaction needs between autonomous vehicles and roadside units.
Quantum Network Slicing:
Using SDN technology for dynamic quantum resource allocation, a smart park project achieved differentiated services for security monitoring (priority QoS) and energy management (standard QoS), improving network utilization by 40%.
Next-generation all-in-one computer touch screens require integration of quantum communication modules and high-performance computing units. Take the USR-EG628 controller as an example:
