IBM and University of Chicago demonstrate quantum advantage with verifiable 70-qubit result

IBM and University of Chicago researchers used a new error-correction technique to encode 70 logical qubits and complete a random circuit sampling task in roughly 15 minutes, a computation that would take leading classical supercomputers an impractical amount of time. The team also designed a more structured circuit approach to verify that the quantum output was actually correct, addressing a longstanding challenge in confirming quantum results once problems exceed classical checking ability. The circuits and data have been published via the Quantum Advantage Tracker.

Mara raises $7M for backpack-sized drone interceptors priced against cheap FPV threats

San Francisco startup Mara raised $7 million in pre-seed funding to build Spike, a portable counter-drone system carried in a backpack. The system pairs a launcher holding up to 48 lightweight 250-gram Seeker interceptors with a Spotter sensor unit that fuses optical, acoustic and optional radar detection to track fiber-optic and autonomous drones that evade radio-frequency jammers. Mara says each Seeker costs roughly the same as the sub-$1,000 FPV quadcopters it's meant to destroy, undercutting rival interceptors by a claimed 20-fold margin.

Nvidia's earnings reveal edge extends beyond GPU chips into full data-center systems

Following its latest earnings report, Nvidia is showing investors that its competitive moat isn't limited to GPU chips, where rivals like Amazon and Google are building in-house alternatives. The company's Vera Rubin architecture bundles GPUs with CPUs, inference accelerators, storage and networking racks, positioning Nvidia as the orchestrator of entire gigawatt-scale AI data centers rather than just a chip supplier.

DRC Ventures Founder Details How Company Values Act as a Decision Filter

An entrepreneur behind more than 22 companies at DRC Ventures argues that corporate values only matter when tested by hard trade-offs, not when displayed as slogans. He describes turning mission statements into operational filters that guide daily decisions on suppliers, partnerships and deals, even when a less principled option would be easier or more profitable.

Entrepreneur Op-Ed: Treat Employee Training as a Competitive Strategy, Not a Checklist

A new Entrepreneur commentary argues that most companies underinvest in training as a strategic tool, focusing instead on sales, tech and operations while overlooking the staff who directly shape customer experience. The author says businesses that link training to standards, coaching and culture—not just task completion—build stronger consistency and retention over time.

Apple's iPhone 18 Pro seen keeping edges over pricier iPhone Ultra foldable

Leaks suggest Apple's upcoming iPhone 18 Pro will retain several advantages over the more expensive iPhone Ultra, including a variable aperture main camera, longer battery life on the Pro Max variant, and continued support for Face ID. The Ultra's ultra-thin foldable design reportedly forces trade-offs, such as dropping Face ID for Touch ID and using a smaller battery than the Pro Max.

Category leadership, not AI content volume, drives brand differentiation

An Entrepreneur contributor argues that as AI makes content production cheaper and more abundant, companies that clearly define and own a market category will stand out faster than those competing purely on content volume. The piece contends that vague, broad positioning makes brands forgettable, while firms that establish a distinct category shape how buyers evaluate the entire market and gain first-mover advantage.
