What is Quantum Advantage?

Introduction to Quantum Computing

Quantum Advantage is the goal of demonstrating that a programmable quantum device can solve a problem that no classical computer can solve in any feasible amount of time

"Quantum advantage refers to the demonstrated and measured success to process a real-world problem faster on a quantum computer than on a classic computer. Since QPUs (quantum processing units) are not yet scalable enough to run some of the larger real-world problems, it could be years before we reach true quantum advantage."

"Quantum supremacy refers to the demonstrated and measured ability to process a problem faster on a quantum computer than on a classic computer.  Note that it’s, any problem, not a real-world problem. Which is a different situation that deserves a different perspective."

"Advantage means you took a problem from a real-world scenario and ran it on a quantum computer with faster, better results.  Real-world, as in real data, real problem, real data volumes with regard to variables, constraints and goals."

"Supremacy means you can solve a very select, non real-world problem and prove that quantum beats classical. It could be any problem, which means it can compute a very small number of variables with minimal constraints."
