Quantum Computers are the devices that perform quantum computations, the study of how to harness quantum physics phenomena to generate novel computer methods.
This type of computer uses qubits, unlike classical computers, which use bits; hence they could only decode data from bits that take the value of 1 and 0; this issue hinders their computing capacity. Quantum computers, conversely, have qubits or quantum bits; they can be 0,1 or a superposition of both; this grows their computing power exponentially.
- allow large-scale parallelism
- tremendous speed
- can solve complex computings and simulations
- permits perfect secure transmission of information
