Is quantum computing the future of computers?

Years ago, I had an interesting experience in a university physics lab. Under the guidance of Prof. Tanaka, we conducted an experiment using superconducting quantum interference devices (SQUIDs) to observe quantum tunneling. These devices were nothing like the classical transistors we know; electrons seemed to pass through potential barriers as if they were ghosts. At that moment, I witnessed something a normal computer’s logic circuits could never do: the system synthesized states that existed simultaneously in parallel universes, merging into one outcome. There may be question marks in our minds about quantum computing, but what physicists aren’t entirely sure about is *how this technology will evolve over time*. Similarly, when the first transistors were invented, even scientists couldn’t predict they’d change everything from keyboards to monitors. The advantages of quantum computers are clear: they have the potential to solve complex equations, calculate factorials of large numbers, or simulate chemical reactions at the molecular level—tasks that classical machines might take hours or even years to complete—in mere seconds. Think of protein folding simulations in the pharmaceutical industry; this requires evaluating millions of possibilities in parallel. That said, it’s still early days for desktop computers. Quantum systems need cold environments to operate, require a large number of quantum bits (qubits) to correct errors, and are still vulnerable to noise. From where we stand now, quantum computing seems poised to revolutionize supercomputers or cloud-based specialized applications. For example, it could break new ground in AI training or logistics optimization. My own experience has shown that no matter how complex technology seems, it eventually becomes ordinary and a part of our lives. Maybe in 20 years, we’ll be hearing about "Quantum Core i9" processors in our desktop PCs—who knows?
