Breaking Down Language Barriers in Quantum Tech: A Universal Translator for a Quantum Network

Scientists at UBC have devised a chip-based device that acts as a “universal translator” for quantum computers, converting delicate microwave signals to optical ones and back with minimal loss and noise. This innovation preserves crucial quantum entanglement and works both ways, making it a potential backbone for a future quantum internet. By exploiting engineered flaws in silicon and using superconducting components, the device achieves near-perfect signal translation with extremely low power use and it all fits on a chip. If realized, this could transform secure communication, navigation, and even drug discovery.

The University of British Columbia (UBC) researchers have proposed a groundbreaking solution to overcome the hurdles in quantum networking. They’ve designed a device that can efficiently convert microwave signals into optical signals and vice versa, which is crucial for transmitting information across cities or continents through fibre optic cables.

This “universal translator” for quantum computers is remarkable because it preserves the delicate entangled connections between distant particles, allowing them to remain connected despite distance. Losing this connection means losing the quantum advantage that enables tasks like creating unbreakable online security and predicting weather with improved accuracy.

The team’s breakthrough lies in tiny engineered flaws, magnetic defects intentionally embedded in silicon to control its properties. When microwave and optical signals are precisely tuned, electrons in these defects convert one signal to the other without absorbing energy, avoiding the instability that plagues other transformation methods.

This device is impressive because it can efficiently run at extremely low power – just millionths of a watt – using superconducting components alongside this specially engineered silicon. The authors have outlined a practical design for mass production, which could lead to widespread adoption in existing communication infrastructure.

While we’re not getting a quantum internet tomorrow, this discovery clears a major roadblock. UBC researchers hope that their approach will change the game by enabling reliable long-distance quantum information transmission between cities. This could pave the way for breakthroughs like unbreakable online security, GPS working indoors, and solving complex problems like designing new medicines or predicting weather with improved accuracy.

The implications of this research are vast, and it’s an exciting time to see how scientists will build upon this discovery to further advance our understanding of quantum technology.

Accelerating Evolution: The Power of T7-ORACLE in Protein Engineering

Researchers at Scripps have created T7-ORACLE, a powerful new tool that speeds up evolution, allowing scientists to design and improve proteins thousands of times faster than nature. Using engineered bacteria and a modified viral replication system, this method can create new protein versions in days instead of months. In tests, it quickly produced enzymes that could survive extreme doses of antibiotics, showing how it could help develop better medicines, cancer treatments, and other breakthroughs far more quickly than ever before.

The accelerated evolution engine known as T7-ORACLE has revolutionized the field of medicine and biotechnology by allowing researchers to evolve proteins with new or improved functions at an unprecedented rate. This breakthrough was achieved by Scripps Research scientists who have developed a synthetic biology platform that enables continuous evolution inside cells without damaging the cell’s genome.

Directed evolution is a laboratory process where mutations are introduced, and variants with improved function are selected over multiple cycles. Traditional methods require labor-intensive steps and can take weeks or more to complete. In contrast, T7-ORACLE accelerates this process by enabling simultaneous mutation and selection with each round of cell division, making it possible to evolve proteins continuously and precisely inside cells.

T7-ORACLE circumvents the bottlenecks associated with traditional approaches by engineering E. coli bacteria to host a second, artificial DNA replication system derived from bacteriophage T7. This allows for continuous hypermutation and accelerated evolution of biomacromolecules, making it possible to evolve proteins in days instead of months.

To demonstrate the power of T7-ORACLE, researchers inserted a common antibiotic resistance gene into the system and exposed E. coli cells to escalating doses of various antibiotics. In less than a week, the system evolved versions of the enzyme that could resist antibiotic levels up to 5,000 times higher than the original.

The broader potential of T7-ORACLE lies in its adaptability as a platform for protein engineering. Scientists can insert genes from humans, viruses, or other sources into plasmids and introduce them into E. coli cells, which are then mutated by T7-ORACLE to generate variant proteins that can be screened or selected for improved function.

This could help scientists more rapidly evolve antibodies to target specific cancers, evolve more effective therapeutic enzymes, and design proteases that target proteins involved in cancer and neurodegenerative disease. The system’s ease of implementation, combined with its scalability, makes it a valuable tool for advancing synthetic biology.

The research team is currently focused on evolving human-derived enzymes for therapeutic use and tailoring proteases to recognize specific cancer-related protein sequences. In the future, they aim to explore the possibility of evolving polymerases that can replicate entirely unnatural nucleic acids, opening up possibilities in synthetic genomics.

Google’s Deepfake Hunter: Exposing Manipulated Videos with a Universal Detector

AI-generated videos are becoming dangerously convincing and UC Riverside researchers have teamed up with Google to fight back. Their new system, UNITE, can detect deepfakes even when faces aren’t visible, going beyond traditional methods by scanning backgrounds, motion, and subtle cues. As fake content becomes easier to generate and harder to detect, this universal tool might become essential for newsrooms and social media platforms trying to safeguard the truth.

In an era where manipulated videos can spread disinformation, bully people, and incite harm, researchers at the University of California, Riverside (UCR), have created a powerful new system to expose these fakes. Amit Roy-Chowdhury, a professor of electrical and computer engineering, and doctoral candidate Rohit Kundu, teamed up with Google scientists to develop an artificial intelligence model that detects video tampering – even when manipulations go far beyond face swaps and altered speech.

Their new system, called the Universal Network for Identifying Tampered and synthEtic videos (UNITE), detects forgeries by examining not just faces but full video frames, including backgrounds and motion patterns. This analysis makes it one of the first tools capable of identifying synthetic or doctored videos that do not rely on facial content.

“Deepfakes have evolved,” Kundu said. “They’re not just about face swaps anymore. People are now creating entirely fake videos – from faces to backgrounds – using powerful generative models. Our system is built to catch all of that.”

UNITE’s development comes as text-to-video and image-to-video generation have become widely available online. These AI platforms enable virtually anyone to fabricate highly convincing videos, posing serious risks to individuals, institutions, and democracy itself.

“It’s scary how accessible these tools have become,” Kundu said. “Anyone with moderate skills can bypass safety filters and generate realistic videos of public figures saying things they never said.”

Kundu explained that earlier deepfake detectors focused almost entirely on face cues. If there’s no face in the frame, many detectors simply don’t work. But disinformation can come in many forms. Altering a scene’s background can distort the truth just as easily.

To address this, UNITE uses a transformer-based deep learning model to analyze video clips. It detects subtle spatial and temporal inconsistencies – cues often missed by previous systems. The model draws on a foundational AI framework known as SigLIP, which extracts features not bound to a specific person or object. A novel training method, dubbed “attention-diversity loss,” prompts the system to monitor multiple visual regions in each frame, preventing it from focusing solely on faces.

The result is a universal detector capable of flagging a range of forgeries – from simple facial swaps to complex, fully synthetic videos generated without any real footage. It’s one model that handles all these scenarios,” Kundu said. “That’s what makes it universal.”

The researchers presented their findings at the high-ranking 2025 Conference on Computer Vision and Pattern Recognition (CVPR) in Nashville, Tenn. Their paper, led by Kundu, outlines UNITE’s architecture and training methodology.

While still in development, UNITE could soon play a vital role in defending against video disinformation. Potential users include social media platforms, fact-checkers, and newsrooms working to prevent manipulated videos from going viral.

“People deserve to know whether what they’re seeing is real,” Kundu said. “And as AI gets better at faking reality, we have to get better at revealing the truth.”

The Niels Bohr Institute at the University of Copenhagen has made a groundbreaking discovery that could revolutionize the way we transmit information. Researchers, in collaboration with the University of Konstanz and ETH Zurich, have successfully sent vibrations through an ultra-thin drumhead, measuring only 10 mm wide, with astonishingly low loss – just one phonon out of a million. This achievement is even more impressive than electronic circuit signal handling.

The drumhead, perforated with many triangular holes, utilizes the concept of phonons to transmit signals. Phonons are essentially sound waves that travel through solid materials by vibrating atoms and pushing each other. This phenomenon is not unlike encoding a message and sending it through a material, where signal loss can occur due to various factors like heat or incorrect vibrations.

The researchers’ success lies in achieving almost lossless transmission of signals through the membrane. The reliability of this platform for sending information is incredibly high, making it a promising candidate for future applications. To measure the loss, researchers directed the signal through the material and around the holes, observing that the amplitude decreased by only about one phonon out of a million.

This achievement has significant implications for quantum research. Building a quantum computer requires super-precise transfer of signals between its different parts. The development of sensors capable of measuring the smallest biological fluctuations in our own body also relies heavily on signal transfer. As Assistant Professor Xiang Xi and Professor Albert Schliesser explain, their current focus is on exploring further possibilities with this method.

“We want to experiment with more complex structures and see how phonons move around them or collide like cars at an intersection,” says Albert Schliesser. “This will give us a better understanding of what’s ultimately possible and what new applications there are.” The pursuit of basic research is about producing new knowledge, and this discovery is a testament to the power of scientific inquiry.

In conclusion, the quantum drumhead revolution has brought us one step closer to achieving near-perfect signal transmission. As researchers continue to explore the possibilities of this method, we can expect exciting breakthroughs in various fields, ultimately leading to innovative applications that will transform our understanding of the world.
