IBM’s Starling quantum computer: 20,000X faster than today’s quantum computers

IBM has just unveiled its boldest quantum computing roadmap yet: Starling, the first large-scale, fault-tolerant quantum computer—coming in 2029. Capable of running 20,000X more operations than today’s quantum machines, Starling could unlock breakthroughs in chemistry, materials science, and optimization.

According to IBM, this is not just a pie-in-the-sky roadmap: they actually have the ability to make Starling happen.

In this exclusive conversation, I speak with Jerry Chow, IBM Fellow and Director of Quantum Systems, about the engineering breakthroughs that are making this possible… especially a radically more efficient error correction code and new multi-layered qubit architectures.

We cover:
- The shift from millions of physical qubits to manageable logical qubits.
- Why IBM is using quantum low-density parity check (qLDPC) codes.
- How modular quantum systems (like Kookaburra and Cockatoo) will scale the technology.
- Real-world quantum-classical hybrid applications already happening today.
- Why now is the time for developers to start building quantum-native algorithms.

Turning trash into treasure: How microwaves are revolutionizing e-waste recycling

You may not have heard of tantalum, but chances are you’re holding some right now. It’s an essential component in our cell phones and laptops, and currently, there’s no effective substitute. Even if you plan to recycle your devices after they die, the tantalum inside is likely to end up in a landfill or shipped overseas, being lost forever.

As a researcher focused on critical materials recovery, I’ve spent years digging through , not seeing it as garbage, but as an urban mine filled with valuable materials like .

Terahertz polarimetry detects microscopic tissue changes linked to cancer and burns

Recent advances in electronics and optics have opened new possibilities for terahertz (THz) waves—an invisible type of light that falls between infrared light and microwaves on the spectrum. The use of THz scattering for medical diagnosis is a promising frontier in this field, as THz waves can probe tissue structures in ways that traditional imaging methods cannot. Emerging THz measurement methods have the potential to detect subtle changes in tissue architecture that occur in diseases like cancer and burn injuries, serving as a powerful diagnostic tool.

However, existing THz imaging techniques face significant limitations for medical applications. Most existing approaches rely primarily on water content differences between healthy and as their main source of diagnostic contrast—an approach that proves overly simplistic for complex disease conditions.

Moreover, while polarization measurements of reflected THz waves seem to be valuable for tissue diagnosis, the underlying mechanisms that create different polarization responses in tissues remain poorly understood. This gap in understanding underscores a need for computational models capable of explaining and predicting the phenomena that researchers have observed experimentally.

Mind-Blowing Speed of Quantum Entanglement Measured for the First Time

In a monumental breakthrough, scientists have measured the speed of quantum entanglement for the first time—an achievement that is set to radically transform the way we understand the quantum world. For years, quantum entanglement was thought to be an instantaneous process, but this new research, published in Physical Review Letters, has pushed the boundaries of our knowledge, providing new insights into the quantum realm and setting the stage for revolutionary advances in data security and computational technologies.

Physicists set new world record for qubit operation accuracy

Physicists at the University of Oxford have set a new global benchmark for the accuracy of controlling a single quantum bit, achieving the lowest-ever error rate for a quantum logic operation—just 0.000015%, or one error in 6.7 million operations. This record-breaking result represents nearly an order of magnitude improvement over the previous benchmark, set by the same research group a decade ago.

To put the result in perspective: a person is more likely to be struck by lightning in a given year (1 in 1.2 million) than for one of Oxford’s quantum logic gates to make a mistake.

The findings, to be published in Physical Review Letters, are a major advance towards having robust and useful quantum computers.

A new way for quantum computing systems to keep their cool

Heat causes errors in the qubits that are the building blocks of a quantum computer, so quantum systems are typically kept inside refrigerators that keep the temperature just above absolute zero (−459 degrees Fahrenheit).

But quantum computers need to communicate with electronics outside the refrigerator, in a room-temperature environment. The metal cables that connect these electronics bring heat into the refrigerator, which has to work even harder and draw extra power to keep the system cold. Plus, more qubits require more cables, so the size of a quantum system is limited by how much heat the fridge can remove.

To overcome this challenge, an interdisciplinary team of MIT researchers has developed a wireless communication system that enables a quantum computer to send and receive data to and from electronics outside the refrigerator using high-speed terahertz waves.

(From 2023)

A new wireless terahertz communication system enables a super-cold quantum computer to send and receive data without generating too much error-causing heat.

Astronomers simulate a star’s final moments as it’s swallowed by a black hole: ‘Breaks like an egg’

The universe is full of spectacular and violent events, but few are more dramatic than a black hole tearing apart a star. Now, thanks to advanced computer simulations, scientists have gotten their closest look yet at what this cosmic catastrophe might actually look — and even sound — like.

A team of astronomers, led by theoretical astrophysicist Elias Most of the California Institute of Technology (Caltech), modeled the dramatic final milliseconds before a neutron star, the incredibly dense core left behind by a massive stellar explosion, is devoured by a black hole.

How artificial retinas could cure blindness | Dante Muratore | TEDxRoma

In this TEDx talk, Dante Muratore shows the transformative potential of brain-computer interfaces. He explains how they can be used to help patients suffering from neurodegenerative diseases, focusing on an artificial retina he and his team are developing to cure blindness in patients with macular degeneration and retinitis pigmentosa. He also describes how brain-computer interfaces will change what it means to be human in the future and challenges us to think deeply about the use we want to make of this technology in society.

Professor of Bioelectronics at Delft University of Technology, where he leads the Smart Brain Interfaces group. His research group explores hardware and system solutions for brain-computer interfaces capable of interacting with the nervous system. The group is working, in collaboration with leading universities in the field, on a microchip to be implanted in the retina to improve the lives of people affected by retinitis pigmentosa and degenerative maculopathy.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Polymer waveguides show promise for reliable, high-capacity optical communication

Co-packaged optics (CPO) technology can integrate photonic integrated circuits (PICs) with electronic integrated circuits (EICs) like CPUs and GPUs on a single platform. This advanced technology has immense potential to improve data transmission efficiency within data centers and high-performance computing environments. CPO systems require a laser source for operation, which can be either integrated directly into the silicon photonic chips (integrated laser sources) or provided externally.

While integrated laser sources allow for dense CPO integration, ensuring consistent reliability can be challenging, which may affect overall system robustness. The use of external laser sources (ELS) in CPO, in comparison, offers improved system reliability.

Single-mode waveguides are crucial components of many PICs, where they help couple light from an external laser to the PIC or distribute optical signals within the system. They are cost-effective and mechanically flexible, besides being highly compatible with electrical circuits. Therefore, they show significant potential for use in CPO systems utilizing ELS.
