Question

1- In your opinion, what is one of the motivations of learning Quantum Computing?
Name one problem in which Quantum Computation excels (compared to classical computation)?

Answer 1

1 Motivation Behind quantum computing - Quantum computing is based on quantum mechanics phenomenon, quantum particles such as photons can occupy two-state simultaneously This principle, called quantum superposition, can be observed in the famous double-slit experiment.

2 Quantum computer can simulate quantum systems, so there is a possible solution for strongly correlated problems (high Tc superconductor) using quantum computation.

3 Quantum computer can solve the hard issues of classical computing using computational power inherent in quantum mechanics. Quantum algorithms can solve some of the NP problems (but not NP-complete) like searching.

4 The security of quantum communication.

5 Quantum computation can break the classical cryptography

Comparative between quantum and classical computing

Quantum computation based on Qbit while classical computing based on the bit,

Classical bits = 0,1

While the quantum bit is described by vector two-dimension Hilbert space
