From: Quantum secure image encryption using hybrid QTRNG and QPRNG
Quantum Gate | Parameter | Purpose | Explanation |
|---|---|---|---|
Pauli X gate | Flips the quantum state \(\:\left|0\right. \rangle\to\:\left|1\right. \rangle\) | State Initialization | It prepares selected qubits for quantum state encoding. |
Hadamard gate | Rotation around Y-axis \(\:\left(\frac{\pi\:}{2}\right)\) and X-axis (\(\:\pi\:)\) | Superposition creation | It converts bases into superposition quantum state. |
Phase gate | Phase shift \(\:\left(\frac{\pi\:}{2}\right)\:,\:\) Rotation around Z axis | Phase modulation | It refining the phase for randomness control |
Double Control Not gate | QTRNG-derived bits | Pseudo random logic using true randomness | It applies double CNOT logic controlled by QTRNG output and generate hybrid random sequences. |
Measurement gate | Output | Generation of hybrid random bits | Measures qubit superposition to extract unpredictable random bits. |
