Quantum Bit Error Rate (QBER) is an essential metric in evaluating the reliability and security of quantum communication systems, important for quantum technologies such as computing and networking. Factors like environmental conditions, hardware quality, and signal. Quantum Key Distribution (QKD) provides information-theoretic security by exploiting the principles of quantum mechanics. Among QKD protocols, the BB84 scheme remains the most widely adopted for both theoretical research and practical implementation. The physical system in the Quantum Key Distri-bution is characterized and the deviations presented due to the imperfections in the realistic devices are taken as a. Quantum Information theory, as an extension of Classical Information theory, has attracted significant attention, with regards to dimensionality reduction,, which can be of significant use for inference and classification tasks related to Machine Learning, quantum embeddings,, exact, and. In semiconductor spin quantum bits (qubits), the radio-frequency (RF) gate-based readout is a promising solution for future large-scale integration, as it allows for a fast, frequency-multiplexed readout architecture, enabling multiple qubits to be read out simultaneously. It has been noticed that the BER performance is improved in an ALOHA based scheme compared to the Superdense coding scheme. However, without using any error correction schemes, the.
