Understanding The Problem Is The Most Important Part Toward Quantum Advantage

Why quantum advantage has nothing to do with speed

The hype surrounding Quantum Computers promises revolutionary speeds. You’ve been told that Quantum Computers are faster. But that’s not true.

If you only look at clock speed, Quantum Hardware is slow. Much slower than classical chips.

Clock speed is not where the promise of Quantum Computing lies.

Fortunately, it is not. This is because some problems become exponentially more difficult as they grow in size. The number of steps required to solve them grows exponentially with the size of the problem. Once this happens, no amount of speed increase would help. Ever. So if Quantum Computers were designed to speed up classical calculations, they would not help us at all with these problems.

Instead, the promise of Quantum Computing lies in solving problems in ways that classical computers never could. It’s about solving them with fewer steps. Ideally, exponentially fewer.
