## Quantum computer

- Uses real gold
- In computers everything is
`0`

and`1`

. Even all characters you type from keyboard are converted to 0s and 1s. Like`A`

is actually`0100 0001`

to computer **Quantum Science**is a branch of physics which deals witht hings which are small, isolated and very cold- Temperature is 10 mili kelvin (room temp 300 K)

### Properties of quantum computer

- Superposition
- you canot thell heads or tails when coin is spinning
- superposition of spins
- entangled
- somethings connected in someway
- interference
- How does headphones cancel noice
- constructiove and destructive interference
`cubits`

of superconduting materialsSimmulating nature, modelling atomic bonding, orbital overlap

HOw do we encode in quantum computer?

Microwaves to manupulate cubit state of superposition and entaglement

classical computung vs quantum computing

Quantum computers can break encryption, whichi are based on prime number base (RSA), Shors algorithm

^{1}Quantum computers are available to use in clouds
