A existent quantum leap
Sometimes subject does make our world move upside down

Scientific American, June 2026
One of nan endemic illnesses of nan American tech manufacture is an addiction to unsupported superlatives: Descriptors for illustration “revolutionary,” “game-changing” aliases “disruptive” are applied to inventions that are astatine champion incremental and astatine worst of nary usage astatine all.
Despite nan truth that I cognize this to beryllium true, I now connection nan pursuing bonzer statements: Quantum computing could alteration nan world. It’s transformative, monumental, unprecedented. A once-in-a-generation exertion that shifts paradigms and ushers successful a caller era of innovation. A quantum leap, even.
Here’s 1 illustration why: Modern finance—our full economical system, really—relies connected public-key cryptosystems that are fundamentally unbreakable. Even nan consumer-level codes that encrypt your online banking are truthful difficult to break that each machine connected nan satellite moving together would request longer than nan property of nan beingness to brute-force them apart.
On supporting subject journalism
If you're enjoying this article, see supporting our award-winning publicity by subscribing. By purchasing a subscription you are helping to guarantee nan early of impactful stories astir nan discoveries and ideas shaping our world today.
A quantum machine could facet those integers and bargain your owe costs successful conscionable a mates of hours.
Of course, there’s a catch, and it’s a large one. Despite immense advances successful nan field, we don’t really cognize really to build a functionally useful quantum machine aliases moreover if specified a point is imaginable astatine all. In this month’s screen story, subject journalist and astrophysicist Adam Becker takes america wrong nan cryogenically chilled bosom of quantum computing to find an answer: Will quantum computers toggle shape medicine, materials subject and cybersecurity, aliases is nan tech manufacture betting billions connected a sci-fi fantasy?
Elsewhere successful nan issue, Scientific American unit newsman Joseph Howlett seeks answers to different arsenic yet unsolved problem that could reshape everything from cryptography to physics: nan Riemann hypothesis, a 167-year-old conjecture truthful difficult to beryllium that apical mathematicians debar moreover trying. “The Scariest Problem successful Math” has a million-dollar reward for its solution, but Howlett explains why hardly anyone is trying to find it.
We besides return clip to bespeak connected a precocious completed accomplishment that has impressed and inspired america all. Over 11 days successful April, the Artemis II satellite mission took humans backmost to nan satellite and farther from Earth than they had ever been before.
Journalist Nadia Drake explains really nan triumphant expedition marks a caller era of lunar exploration, while our ain Joe Howlett explains why Artemis’s early will beryllium a crippled changer for astronomy. In “A Nuclear Moon,” volcanologist and subject writer Robin George Andrews digs into why NASA wants to build a fission reactor connected nan lunar aboveground wrong nan adjacent 5 years and why that scheme isn’t arsenic crazy arsenic it sounds.
Finally, aft each that looking guardant to nan future, we induce you to return a bully stroll down nan roads of our ancient past. Archaeologist Tom Brughmans takes readers connected a travel done a integer mapping task that is transforming what we cognize astir nan Roman Empire by combining centuries-old archaeological records pinch outer imagery and modern topographic data. Brughmans and his squad person assembled nan first high-resolution integer representation of Roman roads that shows nan web mightiness person stretched immoderate 300,000 kilometers, carrying troops, grain, ideas and illness crossed an area rivaling nan modern European Union.
So, yes, superlatives for illustration “revolutionary” and “game-changing” do get thrown astir excessively easily. But arsenic this rumor shows, subject tin make our world move upside down, whether because of a qubit, a conjecture, a moonshot aliases a representation of 2,000-year-old roads. Hyperbole isn’t ever hype; sometimes nan truth catches up.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d for illustration to inquire for your support. Scientific American has served arsenic an advocator for subject and manufacture for 180 years, and correct now whitethorn beryllium nan astir captious infinitesimal successful that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped style nan measurement I look astatine nan world. SciAm always educates and delights me, and inspires a consciousness of awe for our vast, beautiful universe. I dream it does that for you, too.
If you subscribe to Scientific American, you thief guarantee that our sum is centered connected meaningful investigation and discovery; that we person nan resources to study connected nan decisions that frighten labs crossed nan U.S.; and that we support some budding and moving scientists astatine a clip erstwhile nan worth of subject itself excessively often goes unrecognized.
In return, you get basal news, captivating podcasts, superb infographics, can't-miss newsletters, must-watch videos, challenging games, and nan subject world's champion penning and reporting. You tin moreover gift personification a subscription.
There has ne'er been a much important clip for america to guidelines up and show why subject matters. I dream you’ll support america successful that mission.
