Researchers have unveiled long “hidden” and finely detailed tattoo designs on the skin of ancient mummies from Peru, a study reports. Tattoos were a prevalent art form in pre-Hispanic South America, as attested by the discovery of mummified human remains in the region with preserved skin decoration that date back centuries, and even millennia.

While such body art works can provide insights into ancient cultures, tattoos are known to fade and bleed over time — a process compounded in mummies by the decay of the body. This often means that the original designs are difficult to make out.

In the latest study, published in the journal Proceedings of the National Academy of Sciences, a team of researchers used a technique known as laser-stimulated fluorescence (LSF) to examine tattoos on mummified individuals belonging to the pre-Hispanic Chancay culture of what is now coastal Peru.

The mummified remains that team of researchers examined were originally discovered in 1981 at the Cerro Colorado cemetery archaeological site in the Huaura Valley of Peru. The LSF technique revealed “exceptionally fine” and previously unknown details of the ancient tattoos.

The team managed to identify intricate geometric and zoomorphic (representing animal forms) designs that were “very surprising” because they demonstrate a higher degree of artistic complexity than any other existing Chancay artwork, including on pottery and the culture's renowned textiles. The art of tattooing was clearly important to the Chancay, as evidenced by the high proportion of tattooed individuals among known mummified remains from the ancient culture.

For the first time, 2025 will see quantum computers leave labs and research institutions and actually deploy into the networks and data centers of real-world customers. For quantum computing companies, this will be a real test of steel.

It’s one thing to have a groundbreaking, powerful quantum computer that only works on its very best day — when the lab conditions are perfect and when the team of PhDs operating it are at the top of their game. But the reality is that quantum computers need to work on their worst days too — in the real world, in real organizations. The quantum computing companies that land on top will be the ones that have built for this challenge since day one.

People tend to hear the words “quantum computing” and jump straight to science fiction or the multiverse. And while it seems daunting, we’ve actually reached a point where the “quantum” part of quantum computing is the easiest bit — it’s the “computing” that is inherently complex. For those on the front lines of building powerful quantum computers, this means it’s no longer a physics challenge — it’s an engineering one.

Companies won’t need to know the ins and outs of quantum computers in order to leverage its unprecedented power — they’ll simply benefit from its ability to solve the problems that could never be solved on classical computers.
