Quantum Computers: Why They're Faster

Click For Summary
SUMMARY

Quantum computers are faster than classical computers due to their ability to leverage superposition and parallel processing. A qubit, unlike a classical bit, can exist in multiple states simultaneously, allowing for the exploration of all linear combinations of its eigenstates at once. This capability enables quantum computers to perform complex calculations more efficiently than traditional systems, fundamentally changing computational paradigms.

Why quantum computers are faster?
 
Physics news on Phys.org
I have read dome articles about that but still I am confused about parallel processing (and how it is related to superposition)?
Does it mean that we use all linear combinations of the eigenstates of a qubit in the same time? So in contrast to bit, qubit is a unit of information with infinite states, which can be used simultaneously. s this correct?
