PsiQuantum shows quantum chips, PsiCube cooling

PsiQuantum has detailed the photonic quantum chips and cooling system it plans to use for a quantum computer with a million qubits.

The Omega quantum photonic chipset is purpose-built for utility-scale quantum computing and produced by Global Foundries in New York on 300mm wafer. The technology was detailed in a paper in Nature submitted last June and published this week.

This paper shows high-fidelity qubit operations, and a simple, long-range chip-to-chip qubit interconnect – a key enabler to scale that has remained challenging for other technologies.

A Million Qubits Within Reach as Microsoft Redefines Quantum Computing

Microsoft’s Majorana 1 quantum chip introduces a breakthrough Topological Core, enabling stable and scalable qubits.

By leveraging topoconductors, this innovation paves the way for million-qubit machines capable of solving complex scientific and industrial challenges. With DARPA

Formed in 1958 (as ARPA), the Defense Advanced Research Projects Agency (DARPA) is an agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements, by collaborating with academic, industry, and government partners.

A Step Closer to Limitless Energy? Scientists Have Developed a Battery That Runs on Nuclear Waste

Researchers have developed a battery capable of converting nuclear energy into electricity through light emission, according to a new study.

Nuclear power plants generate about 20% of the electricity in the United States and produce minimal greenhouse gas emissions. However, they also generate radioactive waste, which poses risks to human health and the environment, making safe disposal a significant challenge.

To address this, a team led by researchers from The Ohio State University designed a system that harnesses ambient gamma radiation to generate electricity. By combining scintillator crystals—high-density materials that emit light when exposed to radiation—with solar cells, they successfully converted nuclear energy into an electric output powerful enough to run microelectronics, such as microchips.

Chinese Scientists Overcome Key Barrier to Scalable Photonic Quantum Computing

The researchers indicate that several challenges remain. The current system operates at cryogenic temperatures, which limits practical applications. While photons themselves can function at room temperature, the quantum dot requires cooling to maintain stability. Researchers are exploring alternative materials and designs that could allow operation at higher temperatures.

Additionally, the experiment used a single quantum dot, which is not easily scalable to large numbers of qubits needed for universal quantum computing. Future work will need to integrate multiple quantum dots or alternative photon sources that can be mass-produced with high consistency.

Another limitation is the reliance on superconducting detectors with an efficiency of 79%. If detection efficiency is improved beyond 93.7%, the overall system efficiency could surpass the required threshold even further. Advancements in superconducting nanowire technology suggest this is feasible in the near future.

Move Over Smart Rings. MIT’s New Fabric Computer Is Stitched Into Your Clothes

That’s what prompted MIT engineers to create a fabric computer that can be stitched into regular clothes. The device features sensors, processors, memory, batteries, and both optical and Bluetooth communications, allowing networks of these fibers to provide sophisticated whole-body monitoring.

“Our bodies broadcast gigabytes of data through the skin every second in the form of heat, sound, biochemicals, electrical potentials, and light, all of which carry information about our activities, emotions, and health,” MIT professor Yoel Fink, who led the research, said in a press release.

“Wouldn’t it be great if we could teach clothes to capture, analyze, store, and communicate this important information in the form of valuable health and activity insights?”

It seems like something out of a movie — they successfully achieve the first quantum teleportation in history

The future is coming and much faster than we think. Let’s do an exercise of imagination, imagine, for a moment, being able to send information from one point to another without the need for cables, Wi-Fi or traditional signals, more or less like something telepathic, right? Well, that is precisely what scientists have recently achieved at the University of Oxford: teleporting data between two quantum computers. Although it may seem like science fiction or just news, the world.

Although, let’s lower the hype a little, the transmission distance of this experiment was less than two meters, but that doesn’t matter, what matters is having achieved this milestone of sharing information without the need for connections.

Quantum Breakthrough: Microsoft and Purdue Unlock the Future of Topological Qubits

Their work pushes semiconductor-superconductor hybrid technology to new heights and strengthens Purdue’s role in quantum research.

Microsoft Advances Topological Quantum Computing

Microsoft Quantum recently published an article in Nature, highlighting key advancements in measuring quantum devices — an essential step toward building a topological quantum computer. The research was conducted by Microsoft scientists and engineers, including those at Microsoft Quantum Lab West Lafayette, based at Purdue University. In their announcement, the team described the operation of a crucial device that serves as a foundational building block for topological quantum computing. Their findings mark a significant milestone in the development of quantum computers, which have the potential to be far more powerful and resilient than current technologies.

Bubbles That Defy Physics: Scientists Uncover a Mind-Blowing New Phenomenon

A team led by researchers at UNC-Chapel Hill has made an extraordinary discovery that is reshaping our understanding of bubbles and their movement. Imagine tiny air bubbles inside a liquid-filled container. When the container is shaken up and down, these bubbles exhibit an unexpected, rhythmic “galloping” motion—bouncing like playful horses and moving horizontally, despite the vertical shaking. This counterintuitive phenomenon, revealed in a new study, has significant technological implications, from improving surface cleaning and heat transfer in microchips to advancing space applications.

These galloping bubbles are already drawing significant attention. Their impact on fluid dynamics was recently recognized with an award for their video entry at the latest Gallery of Fluid Motion, organized by the American Physical Society.

“Our research not only answers a fundamental scientific question but also inspires curiosity and exploration of the fascinating, unseen world of fluid motion,” said Pedro Sáenz, principal investigator and professor of applied mathematics at UNC-Chapel Hill. “After all, the smallest things can sometimes lead to the biggest changes.”

A new approach to reduce decoherence in superconducting qudit-based quantum processors

Quantum computers, which operate leveraging quantum mechanics effects, could soon outperform traditional computers in some advanced optimization and simulation tasks. Most quantum computing systems developed so far store and process information using qubits (quantum units of information that can exist in a superposition of two states).

In recent years, however, some physicists and engineers have been trying to develop quantum computers based on qudits, multi-level units of quantum information that can hold more than two states.

Qudit-based quantum systems could store more information and perform computations more efficiently than qubit-based systems, yet they are also more prone to decoherence.

Graphyne’s transformation: A new carbon form with potential for electronics

Graphyne is a crystalline form of carbon that is distinct from both diamond and graphite. Unlike diamond, where each atom possesses four immediate neighbors, or graphite, where each atom has three, graphyne’s structure combines two-coordinate and three-coordinate carbons.

Computational models suggest that graphyne has highly compelling electronic, mechanical and . It is predicted to be a semiconductor with a band gap appropriate for electronic devices, ultra-high charge carrier mobility far surpassing that of silicon, and ultimate strength comparable to that of graphene.

Applications of graphyne in electronics, energy harvesting and storage, gas separations and catalysis have been proposed. While graphyne was first theoretically predicted more than three decades ago, its remained elusive.
