|
Light waves overlap and interfere with each other.
|
|
Same amplitude = reinforcement
|
|
Different amplitude = cancel each other out
|
|
|
|
With single photons the same happens!
|
|
Photons are in superposition between two paths
|
|
Possibilities interfere with each other
|

## What is a quantum computer?
|
|
Classical Bits = 0 or 1
|
|
Quantum Computer uses qubits = superposition between 0 and 1
|
|
-> Variables that have all possible values at the same time!
|
|
|
|
### Quantum parallelism
|
|
Quantum computers apply operations to all possible input value at the same time
|
|
After a quantum computer has calculated a superposition of all possible values
|
|
you measure the result and the superposition collapses to a single random f(x) |
