A UK startup has made a revolutionary advancement after delivering the world’s first full-stack quantum computer, built using the same silicon chip technology found in smartphones and laptops.
London-based Quantum Motion, a quantum computing startup that develops scalable quantum computing tech using silicon, launched the industry’s first full-stack quantum computer made with silicon. It was deployed at the UK National Quantum Computing Centre (NQCC).
Black phosphorus nanoribbons (BPNRs), thin and narrow ribbon-like strips of black phosphorus, are known to exhibit highly advantageous electronic properties, including a tunable bandgap. This essentially means that the energy difference between the region where electrons are bound together (i.e., valence band) and that where electrons move freely (i.e., conduction band) can be easily controlled by adjusting the width of the nanoribbons.
A tunable bandgap is essential for the development of transistors, the components that control the flow of electrical current through electronic devices.
While several past studies have highlighted the promise of BPNRs for the development of electronics, strategies that could enable their reliable fabrication on a large scale are still lacking.
Quantum computing, an approach to deriving information that leverages quantum mechanical effects, relies on qubits, quantum units of information that can exist in superpositions of states. To effectively perform quantum computing, engineers and physicists need to be able to measure the state of qubits efficiently.
In quantum computers based on superconducting materials, qubits are indirectly measured by a so-called readout resonator, a circuit that responds differently based on the state of a qubit. This circuit’s responses are probed using a weak electromagnetic wave, which needs to be amplified to enable its detection.
To amplify these signals, also known as microwave tones, quantum technology engineers rely on devices known as amplifiers. Existing amplifiers, however, have notable limitations. Conventional amplifiers can send unwanted noise back to the qubit, disturbing its state. Superconducting parametric amplifiers introduced more recently can be very efficient, but they conventionally rely on bulky and magnetic hardware components that control the direction of signal and protect qubits from backaction noise.
Recent technological advances have opened new possibilities for the development of advanced biomedical devices that could be implanted inside the human body. These devices could be used to monitor biological signals that offer insight about the evolution of specific medical conditions or could even help to alter problematic physiological processes.
Despite their potential for the diagnosis and treatment of some conditions, most implantable devices developed to date are based on rigid electronic components. These components can damage tissue inside the body or cause inflammation.
Some electronics engineers have been trying to develop alternative implantable electronics that are based on soft and stretchable materials, such as polymers. However, most known polymers and elastic materials are not biocompatible, which means that they can provoke immune responses and adversely affect the growth of cells.
In brain-computer interfaces (BCIs) and other neural implant systems, electrodes serve as the critical interface and are core sensors linking electronic devices with biological nervous systems. Most currently implanted electrodes are static: Once positioned, they remain fixed, sampling neural activity from only a limited region. Over time, they often elicit immune responses, suffer signal degradation, or fail entirely, which has hindered the broader application and transformative potential of BCIs.
In a study published in Nature, a team led by Prof. Liu Zhiyuan, Prof. Xu Tiantian and Assoc. Prof. Han Fei from the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences, along with Prof. Yan Wei from Donghua University, have reported a soft, movable, long-term implantable fiber electrode called “NeuroWorm,” marking a radical shift for bioelectronic interfaces from static operation to dynamic operation and from passive recording to active, intelligent exploration.
The design of NeuroWorm is inspired by the earthworm’s flexible locomotion and segmented sensory system. By employing sophisticated electrode patterning and a rolling technique, the researchers transformed a two-dimensional array on an ultrathin flexible polymer into a tiny fiber approximately 200 micrometers in diameter.
Speech recognition without heavy software or energy-hungry processors: researchers at the University of Twente, together with IBM Research Europe and Toyota Motor Europe, present a completely new approach. Their chips allow the material itself to “listen.” The publication by Prof. Wilfred van der Wiel and colleagues appears today in Nature.
Until now, speech recognition has relied on cloud servers and complex software. The Twente researchers show that it can be done differently. They combined a Reconfigurable Nonlinear Processing Unit (RNPU), developed at the University of Twente, with a new IBM chip. Together, these devices process sound as smoothly and dynamically as the human ear and brain. In tests, this approach proved at least as accurate as the best software models—and sometimes even better.
The potential impact is considerable: hearing aids that use almost no energy, voice assistants that no longer send data to the cloud, or cars with direct speech control. “This is a new way of thinking about intelligence in hardware,” says Prof. Van der Wiel. “We show that the material itself can be trained to listen.”
Mayo Clinic researchers have developed a new way to predict whether existing drugs could be repurposed to treat heart failure, one of the world’s most pressing health challenges. By combining advanced computer modeling with real-world patient data, the team has created “virtual clinical trials” that may facilitate the discovery of effective therapies while reducing the time, cost, and risk of failed studies.
“We’ve shown that with our framework, we can predict the clinical effect of a drug without a randomized controlled trial. We can say with high confidence if a drug is likely to succeed or not,” says Nansu Zong, Ph.D., a biomedical informatician at Mayo Clinic and lead author of the study, which was published in npj Digital Medicine.
The ability to generate entangled states of light is a key primitive for quantum communication and distributed quantum computation. Continuously driven sources, including those based on spontaneous parametric downconversion, are usually probabilistic, whereas deterministic sources require accurate timing of the control fields. Here, we experimentally generate entangled photonic modes by continuously exciting a quantum emitter — a superconducting qubit — with a coherent drive, taking advantage of mode matching in the time and frequency domain. Using joint quantum state tomography and logarithmic negativity, we show that entanglement is generated between modes extracted from the two sidebands of the resonance fluorescence spectrum. Because the entangled photonic modes are perfectly orthogonal, they can be transferred into distinct quantum memories. Our approach can be utilized to distribute entanglement at a high rate in various physical platforms, with applications in waveguide quantum electrodynamics, distributed quantum computing, and quantum networks.

NASA announced a trailblazing experiment that aims to take personalized medicine to new heights. The experiment is part of a strategic plan to gather valuable scientific data during the Artemis II mission, enabling NASA to “know before we go” back to the lunar surface and on to Mars.
The AVATAR (A Virtual Astronaut Tissue Analog Response) investigation will use organ-on-a-chip devices, or organ chips, to study the effects of deep space radiation and microgravity on human health. The chips will contain cells from Artemis II astronauts and fly side-by-side with crew on their approximately 10-day journey around the Moon. This research, combined with other studies on the health and performance of Artemis II astronauts, will give NASA insight into how to best protect astronauts as exploration expands to the surface of the Moon, Mars, and beyond.
