2. What is Quantum? Classical Computer vs Quantum Computer
- Molecules (electrons) don’t just go up and down
Superposition the entirety of Quantum Mechanics
- Can represent both a 1 and 0 at the same time
Qubits
- 1 qubit = 2 states
-2 qubits = 4 states
- With every added quantum bit, you double computational power
- 30-qubit computer = faster than world fastest super computer
- 300-quibit computer > all computers in the world connected together

3. Do we need it?
Moore’s law states: Transistors per square inch on circuit boards will double every year.
Moore’s law has slowed down drastically- Do we need faster computers?
Traveling Salesman Problem
- Calculate the fastest and number of routes he can take
- 14 cities = 10^11 possible routes = 100 seconds
- 22 cities = 10^19 possible routes = 1600 years!!

4. Benefits Factor really large prime numbers Better Security…
better weather predictions
Location of distant planets
Better understanding of chemistry = cure for Alzheimer’s disease
Better Security…

5. The Problem First come first serve. 21st century space race.
Easy data breaches
Person data
Military data
Classified government Documents

6. A solution Post-Quantum Cryptography – Quantum Key Distribution
Using Photons to transfer information
Creating a key that is completely random
Generalized Knapsack Code
Developed by Nathan Hamlin
Disguising data with number strings more complex than the zero and one’s modern computers use to operate

7. Final Thoughts Theoretical yet plausible Next 20 – 30 years
Bring awareness
