While it's true that quantum physics introduces inherent uncertainty and probabilistic behavior at the microscopic level, the principles of quantum mechanics do not directly affect the functioning of everyday technologies like GPS and classical computers. The reason is that the behavior of macroscopic systems, such as the devices used in GPS or classical computers, is governed by classical physics rather than quantum physics.
Quantum mechanics is the fundamental theory that describes the behavior of particles at the atomic and subatomic scales. It introduces concepts like superposition and entanglement, which can exhibit counterintuitive behavior. However, at larger scales, these quantum effects tend to average out and are not observed in classical systems.
In the case of GPS, it relies on a network of satellites that transmit signals to receivers on the ground. The precise timing of these signals is crucial for accurate positioning. While atomic clocks on the satellites use quantum phenomena (such as the vibrations of cesium or rubidium atoms) to keep accurate time, the operation of the GPS system as a whole is based on classical physics and mathematical algorithms.
Similarly, classical computers operate based on classical physics and utilize classical bits to process and store information. While they can simulate and model certain aspects of quantum systems, they themselves do not inherently rely on quantum phenomena for their regular operation.
It's important to note that quantum technologies, such as quantum computers, quantum sensors, and quantum cryptography, operate on the principles of quantum mechanics and leverage quantum effects to achieve certain advantages over classical systems. However, everyday technologies that rely on classical physics and classical computing are not directly impacted by the peculiarities of quantum mechanics.
