Quantum technologies are often described as if they operate through a narrow keyhole, letting one fragile process slip through at a time. Work from Bar-Ilan University, described in the paper Multiplexed processing of quantum information across an ultrawide optical bandwidth shows that this picture is far too small. A single beam of quantum light can carry many independent channels at once, each one capable of carrying its own quantum information. The surprising part is that the limitation ha

The race to build a quantum computer capable of breaking modern cryptography has always seemed like a contest of scale. The common belief has been that once someone builds a machine with a million high-quality qubits, the door to factoring classical asymmetric cryptography, such as RSA 2048, will swing open. Yet the closer the field gets to that scale, the more it becomes clear that the real obstacle is not the qubits themselves but the physical burden of supporting them. Q CTRL’s recent work
How smart is today’s artificial intelligence, really? Not in marketing terms, not in sci fi language, but in the sober light of difficult questions like… How many tendons attach to a tiny bone in a hummingbird’s tail? Which syllables in a Biblical Hebrew verse are “closed” according to the latest specialist scholarship? Those are not trivia questions; they are examples from “Humanity’s Last Exam,” a new benchmark that is reshaping how we think about AI progress.[1]
The benchmark comes from a
