4. what is Moore' Law? The deta density of storable information on a silicon circuit, and the correspoding computing speed is doubling every 18 to 24 months. 5. what is quantum computing and what are the two obstacles of quantum computing? How to overcome this problem? Information would not be stored as strings of numbers, but as a series of quantum mechanical states: spin directions of electronis or polarization orientation of photon. The system loses its quantum coherence when heat or light disturbs it and error correction schemes won't work for subtomic. Spread information over several qubits
