Quantum computers can solve certain problems exponentially faster than classical computers
Quantum computers leverage quantum phenomena such as superposition and entanglement to process information in ways that classical computers cannot. This capability allows them to perform some calculations exponentially faster than classical computers.
Example
A quantum computer could theoretically break widely used encryption schemes, which classical computers would struggle with due to the exponential increase in computational power.
Understanding quantum supremacy is crucial for advancing computational capabilities and addressing complex problems in fields like cryptography and physics.
