A few months ago we saw some papers claiming quantum speedups, but they were still on paper—not exactly practical yet. IBM’s 127-qubit Eagle and 433-qubit Osprey processors are out there, but are they truly breaking classical barriers in real workloads? Some argue it’s just hype from noisy intermediate-scale devices. Others point to specific optimizations like variational algorithms where quantum might edge ahead. Where do you stand? Are we already in the quantum advantage era, or are we still in the “wait and see” phase?
Does quantum advantage over classical computing already exist?

Right now, the "quantum advantage" feels a lot like the early days of cloud computing—everyone’s talking about the potential, but real-world impact is still limited. Yeah, IBM’s 433-qubit Osprey can crunch numbers way faster in a lab setting for specific problems (like certain optimization or chemistry simulations), but it’s not exactly replacing your laptop when you’re running Excel or streaming Netflix. The gap between "quantum can do X faster" and "quantum is actually useful for Y in production" is still massive.
Compare it to when GPUs first came out—they were overkill for basic tasks, but then we saw their real value in machine learning and graphics. Today’s quantum computers are like those early GPUs: noisy, limited, and only good for niche stuff. Until we get fault-tolerant, error-corrected systems (maybe a decade away?), classical methods like GPUs or specialized hardware (TPUs, FPGAs) are still the go-to for most workloads. Quantum might be the future, but it’s not the present—yet.
