Researchers Create World's First Completely Verifiable Random Number Generator

1 month 1 week ago
Researchers have built a breakthrough random number generator that solves a critical problem: for the first time, every step of creating random numbers can be independently verified and audited, with quantum physics guaranteeing the numbers were truly unpredictable. Random numbers are essential for everything from online banking encryption to fair lottery drawings, but current systems have serious limitations. Computer-based generators follow predictable algorithms -- if someone discovers the starting conditions, they can predict all future outputs. Hardware generators that measure physical processes like electronic noise can't prove their randomness wasn't somehow predetermined or tampered with. The new system, developed by teams at the University of Colorado Boulder and the National Institute of Standards and Technology, uses quantum entanglement -- Einstein's "spooky action at a distance" -- to guarantee unpredictability. The setup creates pairs of photons that share quantum properties, then sends them to measurement stations 110 meters apart. When researchers measure each photon's properties, quantum mechanics ensures the results are fundamentally random and cannot be influenced by any classical communication between the stations. The team created a system called "Twine" that distributes the random number generation process across multiple independent parties, with each step recorded in tamper-proof digital ledgers called hash chains. This means no single organization controls the entire process, and anyone can verify that proper procedures were followed. During a 40-day demonstration, the system successfully generated random numbers in 7,434 of 7,454 attempts -- a 99.7% success rate. Each successful run produced 512 random bits with mathematical certainty of randomness bounded by an error rate of 2^-64, an extraordinarily high level of confidence.

Trump Organization Announces Mobile Plan, $499 Smartphone

1 month 1 week ago
The Trump Organization on Monday unveiled a mobile phone plan and a $499 smartphone that is set to launch in September. CNBC: The new service, Trump Mobile, will offer a $47.45-per-month plan that includes "unlimited" talk, text and data, as well as roadside assistance and a "Telehealth and Pharmacy Benefit," according to its website. The company, owned by President Donald Trump, also announced it will sell a "T1" smartphone, which appears to feature a gold-colored metal case etched with an American flag.
