This research focuses on the development of a Quantum Random Number Generator (QRNG) using the Hadamard-CNOT (HCNOT) scheme implemented on the IBM QX quantum computing platform. QRNG is a critical component in various cryptographic and simulation applications, which require high-quality bilangan acak sources. The proposed method leverages the intrinsic properties of quantum mechanics to generate truly unpredictable bilangan acaks. In this study, we employed Hadamard and CNOT gates to create quantum superposition and entanglement. The Hadamard gate is used to produce balanced superposition, while the CNOT gate is utilized to create correlations between kubit s. After quantum measurement, we applied a post-processing technique using an XOR bitmask to enhance the quality of the bilangan acak distribution. The QRNG implementation was carried out on the IBM QX platform, which provides access to real quantum hardware via the cloud. We conducted a series of experiments and statistical analyses to evaluate the performance of the proposed QRNG, including randomness testing using standard suites such as NIST SP 800- 22 and 90B. The research results indicate that the proposed HCNOT-based QRNG is capable of producing high-quality random number which passed 13 out 15 tests after post- processing using XOR bitmask. This research contributes to the development of secure and efficient bilangan acak sources for quantum in the quantum computing era.
