Scientists at National Tsing Hua University (NTHU) in Taiwan have created what they call the world’s smallest quantum computer — a device that works using only one photon of light.

Instead of relying on many qubits like traditional quantum computers, this system encodes information in 32 different time slots (or “time-bins”) of a single photon. Each time-bin acts like a dimension, allowing the photon to carry multiple pieces of quantum information at once.

The computer is so small it can fit on a desk and operates at room temperature, unlike most quantum computers that need extremely cold environments. Despite its tiny size, the researchers successfully demonstrated that it can run basic quantum algorithms, such as factoring numbers (like 15 = 3 × 5), showing real computational potential.

OpenAI has recently introduced stricter content policies to limit ChatGPT’s ability to provide medical or legal guidance. While it can still explain general concepts, definitions, or research findings, it now avoids giving personal or case-specific recommendations — instead directing users to licensed professionals for safety and accountability.

The change comes after concerns from regulators and medical boards about misinformation risks, especially as AI tools became popular for diagnosing symptoms or suggesting treatments. OpenAI’s move aligns with growing global standards around responsible AI use, ensuring that sensitive advice isn’t mistaken for professional consultation.

Interestingly, this decision follows a wave of studies showing AI’s potential to outperform humans in areas like disease detection, contract analysis, and case prediction. But despite its impressive accuracy, ChatGPT’s creators emphasize that it’s a tool, not a substitute for certified experts — reinforcing that technology’s role is to assist, not replace, human judgment.

In a world-first, U.S. researchers have teleported a quantum state of light across 30 kilometers of standard internet fiber while normal web traffic flowed through the same cables.

This marks the first time quantum teleportation has succeeded over a live, public-style network. The team synchronized quantum photons with regular data signals, keeping their fragile quantum properties intact throughout the journey.

The result? Proof that quantum communication can coexist with today’s internet no massive infrastructure overhaul needed.

The implications are staggering: ultra-secure, unhackable communication, powered by the laws of physics. The dream of a global quantum internet is no longer science fiction it’s happening now.

In a stunning discovery, computer programmer Harishankar Narayanan found that his $300 iLife A11 smart vacuum was secretly transmitting detailed 3D maps of his home to remote servers overseas. Using tools to monitor his home network, he uncovered that the vacuum’s built-in software—powered by Google Cartographer mapping tech—was broadcasting private spatial data “halfway across the world.”

When Narayanan blocked the vacuum’s data transmissions (but allowed firmware updates), the device abruptly stopped functioning. After repeated repair attempts failed and the warranty expired, he decided to investigate deeper. What he found was alarming — the vacuum’s Android Debug Bridge (ADB) was left wide open, granting full root access to anyone who connected.

Even more shocking, a timestamped line of code matched the exact moment his device went offline — a remote kill command issued by the manufacturer. After reversing the script, the vacuum instantly came back to life, confirming his worst suspicions: it had been remotely disabled.

This case highlights growing concerns about data privacy in smart home devices, many of which have unrestricted cloud connectivity. Experts are urging consumers to research and monitor IoT products before bringing them into their homes — because convenience might come at the cost of privacy.
