2. Motivation & Problems
Provide a solution for real world problem
1. Security issues in logistic
2. The noise problem in NISQ era
3. Make a real blockchain use case;
with quantum computing
4. Contribute to the Qiskit community

Our Work
Ⅰ
Set-up
Cloud
Server
Ⅱ
Build
QRNG with
Qiskit
Ⅲ
Build a code
for blockchain
application
goorm.io

7. Build QRNG with Qiskit
Make hash values with 48 qubits
Jacak, J.E., Jacak, W.A., Donderowicz, W.A. et al. Quantum
random number generators with entanglement for public
randomness testing. Sci Rep 10, 164 (2020).
q = QuantumRegister(48)
c = ClassicalRegister(48)
circuit = QuantumCircuit(q,c)
circuit.h(q)
for i in range(47):
circuit.cx(q[i], q[47])

8. Build a code for blockchain application
1. Build a website (Input email)

9. Build a code for blockchain application
2. Blockchain; make blocks
1. Email + QRNG
= Key Value
2. Klaytn Blockchain
Node Call for
Transaction
3. Write the Block for
Key Value and then
Receive the txHash
Value
4. Check the txHash
Value in Klaytnscope
5. Block record proof
for tracking shipments

10. Conclusion
Email + Hash
1. Satisfiy the industrial blockchain
transaction standard
2. Cannot change saved key-value

11. Future Prospects
1. Use this
system for
delivering
REAL SWAG
2. Utilize
for other
blockchain
services

12. Stay safe at home.
SWAG will be delivered
to your home safely!

13. Thank you for listening
