Quantum-lattice BlockChain Structure

• Index
• Timestamp
• Data
• Quantum Key
• hash (lattice-based)

Quantum Key Distribution ( based on BB92 protocol)

• Simulate BBM92 quantum key distribution protocol
• Creation of two quantum circuits named Alice and Bob
• Apply Hadamard gate on Alice's qubit, measure it, and share the circuit state with Bob
• Simulate circuits, compare results, and establish a secure key

Latice Based Hash

• Take index, previous_hash, timestamp, data, quantum_key as input
• Calculate hash using lattice-based hash function
• lattice-based hash function employs SHAKE-256 algorithm and large prime modulus for message digest and producing lattice-based hash using previous_hash
