Optimization of quantum computations: the impact of the Doppler effect on cubit coherence

The Doppler effect, arising from the relative motion between the source and the observer, plays a significant role in quantum computations, particularly in the context of decoherence and the state of qubits. In quantum systems where information is encoded in the states of qubits, changes in the frequency of photons caused by the Doppler effect can lead to coherence violations and a decrease in computational accuracy. These changes can cause state mixing and complicate the management of quantum interactions, increasing the probability of errors. Understanding and accounting for the Doppler effect is critically important for designing robust quantum systems, as it can manifest in various types of qubits, including photonic, atomic, and ion qubits. To minimize the impact of the Doppler effect, it is necessary to develop error correction methods and utilize technologies such as polarizing filters or feedback systems. Thus, studying the Doppler effect deepens our understanding of the mechanisms of decoherence and contributes to the creation of more stable and efficient quantum computing systems.
