How close are quantum computers to being really useful? Podcast
Quantum computers could revolutionize science by solving complex problems. However, scaling and error correction remain significant challenges before achieving practical applications.
Quantum computers have the potential to solve big scientific problems that are beyond the reach of today’s most powerful supercomputers, such as discovering new antibiotics or developing new materials.
But to achieve these breakthroughs, quantum computers will need to perform better than today’s best classical computers at solving real-world problems. And they’re not quite there yet. So what is still holding quantum computing back from becoming useful?
In this episode of The Conversation Weekly podcast, we speak to quantum computing expert Daniel Lidar at the University of Southern California in the US about what problems scientists are still wrestling with when it comes to scaling up quantum computing, and how close they are to overcoming them.
Quantum computers harness the power of quantum mechanics, the laws that govern subatomic particles. Instead of the classical bits of information used by microchips inside traditional computers, which are either a 0 or a 1, the chips in quantum computers use qubits, which can be both 0 and 1 at the same time or anywhere in between. Daniel Lidar explains:
“Put a lot of these qubits together and all of a sudden you have a computer that can simultaneously represent many, many different possibilities … and that is the starting point for the speed up that we can get from quantum computing.”
Faulty qubits
One of the biggest problems scientist face is how to scale up quantum computing power. Qubits are notoriously prone to errors – which means that they can quickly revert to being either a 0 or a 1, and so lose their advantage over classical computers.
Scientists have focused on trying to solve these errors through the concept of redundancy – linking strings of physical qubits together into what’s called a “logical qubit” to try and maximise the number of steps in a computation. And, little by little, they’re getting there.
In December 2024, Google announced that its new quantum chip, Willow, had demonstrated what’s called “beyond breakeven”, when its logical qubits worked better than the constituent parts and even kept on improving as it scaled up.
Lidar says right now the development of this technology is happening very fast:
“For quantum computing to scale and to take off is going to still take some real science breakthroughs, some real engineering breakthroughs, and probably overcoming some yet unforeseen surprises before we get to the point of true quantum utility. With that caution in mind, I think it’s still very fair to say that we are going to see truly functional, practical quantum computers kicking into gear, helping us solve real-life problems, within the next decade or so.”

🕒 [UPDATE] Orion Performs Translunar Injection Burn
The spacecraft has completed its critical engine burn, sending Artemis II on a trajectory toward the Moon. This marks the official start of its deep space journey.
Artemis II Successfully Launches
CAPE CANAVERAL, Fla. — NASA has successfully launched its Artemis II mission, marking the first crewed journey toward the Moon in more than 50 years.
The powerful Space Launch System (SLS) rocket lifted off from Kennedy Space Center on April 1, carrying four astronauts on a 10-day mission around the Moon and back.
On board are Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Canadian astronaut Jeremy Hansen. The mission is already being hailed as a major milestone in NASA’s effort to return humans to deep space.
Shortly after liftoff, the Orion spacecraft successfully reached orbit and deployed its solar arrays, beginning its journey that will eventually send the crew on a translunar trajectory toward the Moon. 
Artemis II is a lunar flyby mission, meaning astronauts will not land but will travel farther from Earth than any human mission in decades while testing critical systems needed for future landings.
The mission also marks several historic firsts, including the first woman and the first person of color—Victor Glover—to travel into lunar space.
NASA says the mission is a key step toward future lunar landings and long-term plans to establish a human presence on the Moon later this decade.
🛰️ Artemis II Mission Timeline
The 10-day Artemis II mission follows a carefully planned trajectory from Earth to the Moon and back:
- Day 1: Launch and Earth orbit
- Day 1–2: Translunar injection burn
- Days 2–4: Deep space travel
- Days 4–5: Lunar flyby
- Days 5–8: Return to Earth
- Days 9–10: Reentry and splashdown

CropX Technologies has launched CropX Vision, a new AI-powered vineyard monitoring solution designed to help growers measure vine water stress using a single canopy image.
The new tool uses computer vision and agronomic modeling to estimate leaf water potential from a smartphone photo, giving growers and agronomists a faster and more scalable way to assess plant stress across entire vineyard blocks. The company says the goal is to support better irrigation decisions throughout the growing season.
CropX Vision is available globally on both iOS and Android. The platform is also integrated into the broader CropX application, allowing users to combine canopy-based stress insights with other agronomic data in one place.
According to CropX, the technology offers an in-season alternative to traditional pressure chamber measurements, which can be more time-consuming and limited in sampling range. Instead of relying on specialized equipment, growers can capture a single image in the field and receive plant-level water stress insights.
The product builds on technology originally developed by Tule Technologies, a California-based precision irrigation company acquired by CropX in 2023. Tule’s canopy sensing technology has already been used in California vineyards, and CropX is now expanding that capability to growers worldwide.
CropX says the global release reflects its continued focus on data-driven tools that help growers improve productivity while managing water more efficiently.
CropX Vision is now available for download via the app stores:
- iOS: https://apps.apple.com/nl/app/cropx-vision/id6756921607?l=en-GB
- Android: https://play.google.com/store/apps/details?id=com.cropx.cropx_vision&pcampaignid=web_share

Unilever, Google Cloud Strike Five-Year AI Partnership to Reshape Consumer Goods Marketing
Unilever and Google Cloud have announced a five-year partnership aimed at accelerating the consumer goods giant’s digital transformation through AI, cloud infrastructure, and data modernization.
The deal centers on helping Unilever strengthen brand discovery, marketing measurement, and AI-driven customer engagement across its global portfolio, which includes Dove, Vaseline, and Hellmann’s. A major focus is the rise of conversational and agentic commerce, where consumers increasingly discover and shop for products through AI-powered interactions rather than traditional search and browsing.
As part of the agreement, Unilever will migrate its integrated data and cloud platform to Google Cloud, creating what the companies describe as an AI-first digital backbone. That system is intended to help Unilever move faster on demand generation, turn data into actionable insights, and respond more quickly to shifts in the market.
The partnership is built around three pillars:
- Agentic commerce and marketing intelligence
- An integrated data and cloud foundation
- Advanced AI adoption across the business
Unilever leadership framed the move as part of a broader shift in which technology is becoming central to value creation in the fast-moving consumer goods sector. Google Cloud said the collaboration will use advanced AI models, including Gemini, to help modernize business processes and improve agility.
Unilever said it generated €50.5 billion in sales in 2025, operates in more than 190 countries, and reaches 3.7 billion people every day.
What to watch for
- How “agentic commerce” changes consumer brand discovery
- Whether other major CPG companies follow with similar AI-cloud partnerships
- How AI-backed marketing measurement impacts ad efficiency and conversion
