In quantum computing, maintaining precise environmental conditions is paramount. Polyester felt, with its excellent insulation properties, is playing a role in shielding quantum computing systems from external disturbances. These systems are highly sensitive to temperature fluctuations, electromagnetic interference, and vibrations. Polyester felt – based insulation layers can be used to wrap delicate quantum components, reducing heat transfer and minimizing the impact of external vibrations. By creating a more stable environment, polyester felt helps ensure the accurate operation of quantum bits (qubits), which are the building blocks of quantum computers. This stability is essential for achieving reliable quantum computations and advancing the field towards practical applications.​

For quantum communication, security is a top concern. Polyester felt can be incorporated into the packaging and shielding of quantum communication devices. In fiber – based quantum communication systems, protecting the quantum – sensitive fibers from physical damage and external interference is crucial. Polyester felt’s soft yet durable texture provides a cushioning effect, safeguarding the fibers from mechanical stress during installation and operation. Additionally, polyester felt with electromagnetic – shielding properties can be used to prevent eavesdropping on quantum communication channels. By blocking unwanted electromagnetic signals, it helps maintain the integrity and security of quantum – encrypted data transmission, ensuring that sensitive information remains protected.​

In quantum sensing applications, polyester felt is also finding its niche. Quantum sensors rely on the unique properties of quantum systems to detect minute changes in physical quantities such as magnetic fields, temperature, and acceleration. Polyester felt can be used to create holders and mounts for these sensors, providing a stable and non – magnetic base. Its low – magnetic – susceptibility property ensures that it does not interfere with the highly sensitive measurements of quantum sensors. Moreover, polyester felt can be customized to fit the specific requirements of different quantum sensing setups, allowing for precise positioning and alignment of the sensors, which is critical for obtaining accurate and reliable sensing results.​

As quantum technology continues to progress, the demand for materials that can support its development will only increase. Polyester felt, with its combination of practical properties and cost – effectiveness, is likely to become an even more important component in the quantum technology ecosystem. Researchers and engineers are constantly exploring new ways to optimize the use of polyester felt in quantum applications, and with ongoing innovation, this humble material may contribute significantly to the realization of the full potential of quantum technology.
