Quantum Supremacy and Quantum Advantage
Quantum supremacy is a time period used to describe the
factor at which a quantum pc can carry out a selected venture quicker than any
classical computer, no matter its length or velocity. In 2019, Google claimed
to have executed quantum supremacy whilst its quantum processor, Sycamore,
solved a selected trouble faster than the most advanced classical
supercomputers.
Quantum advantage, then again, refers back to the broader
state of affairs wherein quantum computer systems can outperform classical
computer systems for practical and significant obligations. While quantum
supremacy is a huge milestone, quantum advantage is the last aim, because it
holds the potential to convert industries and resolve troubles which can be
presently intractable.
