Quantum computing has alternated between breakthrough darling and overhyped promise in technology circles. Its powerful new capabilities come with a threat to break current cryptography, but for business leaders navigating the noise, the signal should be clear: post-quantum cryptography (PQC) is a manageable evolution, not a crisis.

The mathematics behind today’s encrypted digital transactions may yield to quantum computers one day, but the transition to quantum-resistant algorithms is neither sudden nor insurmountable. For executives concerned about disruption, cost, or complexity, a structured and phased approach exists with trusted technology partners like Intel that are already beginning to deliver the infrastructure to make it possible.

A natural evolution, not a cliff edge

The “quantum threat” narrative often swings between two extremes: imminent catastrophe or distant irrelevance. The reality occupies a more pragmatic middle ground. Quantum computers are highly specialized accelerators that exploit quantum physics

The machine that could change the world will be housed in a room that looks like a data center crossed with an ice cream factory. Inside will be some 100 stainless-steel cabinets, each about six feet tall and connected to a supply of liquid helium that keeps them only a few degrees above absolute zero. Inside those cabinets will be hundreds of chips, and on those, thousands of particles of light flying through a maze of optical switches and beam splitters. Each photon must be accounted for, because precisely measuring where it ends up will help answer questions that current computers might take millions of years to solve.

This computer, as described, does not exist. It’s the brainchild of a company called PsiQuantum, founded in 2016 by four physicists from UK universities. In a crowded field of deep-pocketed competitors with similarly fantastical visions, the

Building up: IBM has unveiled a prototype chip that stacks transistors in two vertical layers—a design the company calls a nanostack—doubling the density of its previous state-of-the-art tech and fitting roughly 100 billion transistors onto an area the size of a fingernail.
A meaningful leap in performance: Compared to IBM’s previous state-of-the-art approach, the new design can be used to make chips that handle up to 50% more work in the same amount time and run up to 70% more efficiently—gains that could meaningfully improve energy use in data centers within a decade.
Not without complications: The technology is not yet in production, and stacking transistors introduces real manufacturing headaches: more transistor layers opens up more room for errors, and engineers must build each tier without generating enough heat to melt the connections below—a constraint IBM has solved, though it won’t say how.” data-chronoton-post-id=”1139696″ data-chronoton-expand-collapse=”1″

The changes may be less perceptible than in smartphones, tablets, or wearables, but chargers have also been quietly reinvented over the last decade. At one time a bulky mix of tangled cables and connectors, slow to perform and prone to overheating, they’re now smaller, safer, and faster, thanks to a slew of technological advances.

These advances include a switch to gallium nitride (GaN), which has now usurped silicon as the preferred semiconductor, capable of handling higher voltages, faster switches, and more efficient conduction. Multi-port chargers, coupled with an industry-wide shift toward USB-C standardization, mean a single charger can handle multiple devices. And early smart chargers are also trickling onto the market, able to dynamically distribute power and carry out autonomous safety checks.

Combined, these have repositioned chargers as differentiated standalone devices, rather than peripheral accessories.

But, manufacturers say there is much further to
