For every breathless new reports of game-changing breakthroughs, the reality of having a Mister Fusion on our flying cars remains as elusive as the climate-induced end of the world. Then there’s quantum computing. This one has been five years away for a lot less than the others, but it doesn’t seem any closer to fruition. Like fusion, there’s occasional breakthrough announcements but realistically working quantum computers…? Five years, tops. Or maybe not. First off: what *is* quantum computing? A normal computer is *binary*, that is its most basic component, the bit, is like a light switch: either on or off. The basic component of quantum computers is a qubit, which is more like a spinning coin that is both heads and tails at the same time while it’s in the air. Only when it lands (when you measure it) does it settle into one definite answer. Because of this ‘both-at-once’ property, a handful of qubits can explore a huge number of possibilities simultaneously. That is why, for certain very specific problems, such as factoring huge numbers, simulating molecules, or searching unsorted data, a quantum machine could, in theory, finish the job far faster than any conventional supercomputer. The catch is that the whole arrangement is incredibly fragile. Any tiny vibration, temperature change or stray electromagnetic noise collapses the delicate quantum state, which is why today’s machines need to be kept colder than outer space and still make a lot of errors. So while the idea is real and the early prototypes exist, practical, large-scale quantum computers that outperform ordinary ones on everyday tasks remain years, possibly decades, away. Then there’s the matter of the software to run the hardware. > [Currently, the](https://www.newscientist.com/article/2582565-why-full-fledged-quantum-computers-might-always-be-five-years-away/?ref=goodoil.news) quantum computing industry has its sights on reaching “fault tolerance”, or building a quantum computer that is so good at catching its own errors that it can reliably run unprecedentedly complex computations. Once this goal is reached – and many firms are projecting they will do so by the end of the decade – will quantum computers have arrived? Will we know which type of qubit won the quantum-computing race? And what will be the next milestone? Well, getting past the field’s own little replication crisis would be a start. > [The results of most](https://www.newscientist.com/article/2584476-quantum-computing-may-be-facing-a-replication-crisis/?ref=goodoil.news) scientific papers reporting on advances in quantum computers can’t be replicated, according to a new analysis. This may undermine the credibility of some of the achievements that the quantum computing industry has reported in recent years, kicking off a replication crisis in the fast-growing field. Of a hand-checked sample of 127 recent papers, only about a quarter even bothered to supply code that anyone else could attempt to run. Of those that did, nearly two-thirds of the code failed to work. A broader automated sweep of almost five thousand papers found the same dismal pattern: barely more than a quarter provided enough information for an independent researcher to try replicating the claimed results. > **Wolfgang Mauerer** at the Technical University of Applied Sciences Regensburg in Germany \[…says\] “We did a smaller-scale study four or five years ago, and we already found that the situation is bad, but it didn’t really improve over time,” he says. “We thought the numbers would be better by now.” You guessed it: they aren’t. The usual excuses are already circulating. Quantum hardware is still immature and maddeningly variable: what works on one machine today may not work on another tomorrow, even when both are rented through the same cloud service. Software in a fast-moving field is a ‘living thing’ that needs constant community maintenance. Innovation, we are told, matters more than boring old reproducibility while the technology is young. AI coding agents will soon tidy everything up. All of which may contain a grain of truth. It is also a remarkably convenient set of explanations for an industry that has spent years issuing breathless announcements of breakthroughs that largely evaporate under scrutiny. It’s not just a spherical chicken in a vacuum, the chicken is also locked in a box with **Erwin Schrödinger**’s cat. Conventional computer science took decades to demand proper standards of reproducibility. Quantum computing appears determined to stretch that timeline even further while still insisting the revolution is only five years away. In other words, the spinning coin remains in the air. Whether it will ever land on a result that other people can actually check is, for the moment, anyone’s guess. Meanwhile, the spin goes on. --- 💡 ****If you enjoyed this article please share it using the share buttons at the top or bottom of the article.**
