Motivation

Let's design the alternative Internet using the quantum computer technology

What to Learn from this paper

Q1. Can we construct the Internet with the quantum computer technology?
Q2. How can we build the distributed quantum network?
Q3. What is the difference (restrictions) between the classic and the quantum network?

Q1. Can we construct the Internet with the quantum computer technology?

A1. Yes, but the quantum network is not equivalent to the classic network.

Q2. How can we build the distributed quantum network?

Prerequisite Knowledge
1. the classic network architecture
2. basic knowledge about quantum computing

1. the classic network architecture

2. basic knowledge about quantum computing

a. Qubit
b. EPR pair
c. Teleportation
d. Purify and Swap (proposed Quantum Error Correction mechasnim)

a. Qubit

The unit of quantum information

Unlike classic bit, a qubit has three states; 0, 1 and superposition

A qubit has globally unique but limited number of patterns

You can measure the patterns of quantum state with 100% probability

No clone

b. EPR pair

group of qubits exhibiting strong correlation between two qubits

c. Teleportation

an idea to transfer a qubit

e.g., send 1001 from A to B

d. Purify and Swap

- proposed Quantum Error Correction mechasnim

step1: find the EPR pair
step2: measure patterns of a qubit
step3: swap a qubit
step4: agree to begin quantum communication

Q2. What is the design of the quantum network?

A2. QRNA (Quantum Recursive Network Architecture)
- vertical network architecture for protocol stacks
- horizontal network architecture for application design

Vertical QRNA

Horizontal QRNA

Q3. What is the difference between the classic and quantum network?

Conclusion

QRNA is the proposed concept of the distributed quantum network

future work: engineering the network
