1. Quantum Computers

2. Brief Overview History of Quantum Computing
Theory Behind Quantum Computers
Current Status
Problems Being Faced
Future Outlook

3. History of Quantum Computers
Originally begun in late 1970s
Came out of consideration of Moore's Law
Attempt to get around physical limitations
Applications considered were simulations of Quantum Physics
Remained curiosity until more uses discovered

4. Quantum Computer Theory
Qubits replace normal bits
Values become 0, 1, or a superposition of those
Example :
State Amplitude Probability
(a+ib) (a2+b2) i i i i i i i i

5. Theory cont. States are changed using small pulses of EM radiation
Algorithms will reduce all probabilities to 0 except one which will be returned.
After reading a single measurement, uncertainty will change system

6. Current Progress
Biggest quantum computer developed so far is 7 qubits big
NMR has emerged as best technology to read data from quantum computers
Progress limited by several problems

7. Problems 3 main problems: Decoherence Error Correction
Quantum hardware

8. Future Outlook
