The quantum internet, explained
The quantum internet is a network of quantum computers that will someday send, compute, and receive information encoded in quantum states. The quantum internet will not replace the modern or “classical” internet; instead, it will provide new functionalities such as quantum cryptography and quantum cloud computing.
While the full implications of the quantum internet won’t be known for some time, several applications have been theorized and some, like quantum key distribution, are already in use.
It’s unclear when a full-scale global quantum internet will be deployed, but researchers estimate that interstate quantum networks will be established within the United States in the next 10 to 15 years.
Microcombs unlock 112Gbps wireless link at 560GHz for 6G
Researchers at Tokushima University have demonstrated single-channel wireless transmission at 112 Gbps in the 560 GHz band using soliton microcombs, marking a significant step toward next-generation 6G communications.
Conventional electronic technologies face fundamental limitations in generating stable high-frequency signals beyond 350 GHz, including reduced output power and increased phase noise. These challenges have hindered the realization of ultra-high-speed wireless communication in the terahertz regime, which is expected to play a key role in future 6G systems.
Microcomb system tackles key hurdles To overcome these challenges, the research team developed a microcomb-driven terahertz wireless communication system that combines fiber-coupled microcombs with high-order modulation techniques. The system leverages the high frequency stability and low phase noise of microcombs to generate a low-noise terahertz carrier.
Harvard Publishes a Longevity Report for the General Public
The report, titled “Pathways to Longevity”, introduces several important longevity concepts to the general reader and is another sign that the field is coming of age and entering the mainstream.
People do want to live longer
From time to time, Harvard Health Publishing issues Special Health Reports – consumer-facing, doctor-reviewed guides translating medical research for general readers. Previous reports included topics such as Alzheimer’s and heart disease. This new one, presented to the public earlier this week, is dedicated to healthy longevity. While this report, aimed mostly at curious laypeople and priced at $29, might not reveal a trove of new information to a longevity-savvy reader, it is an unmistakable sign that longevity science and the very idea of extending lifespan and healthspan are finally entering the mainstream.
Anthropic CEO Dario Amodei Talks Scaling Laws, AI Arms Races, and Radical Abundance
This video features a conversation with Dario Amadei, CEO of Anthropic, discussing the intersection of AI and economics. Viewers will gain insights into how technological innovation impacts business processes and models, the future landscape of AI companies, and the potential societal ramifications of advancements in AI technology. The main theme emphasizes the evolving dynamics between innovation and established business strategies in the AI sector, as well as the importance of understanding how these changes affect both markets and society.
Solar-powered desalination system turns ocean water into drinking water, without waste
The United Nations estimates that 2.2 billion people lack safely managed drinking water, and communities from California to the Middle East rely on desalination plants to convert ocean water to fresh water. Common desalination techniques such as reverse osmosis and thermal distillation are energy-intensive, require pre- and post-water treatment, and leave behind a concentrated saltwater byproduct called brine that wreaks havoc on sea life when it’s deposited back into the ocean by raising the salt level and lowering oxygen in the water.
Researchers block key protein that helps Parkinson’s spread through the brain
A newly identified protein called GPNMB may play a major role in helping Parkinson’s disease spread through the brain. Researchers discovered that immune cells release the protein in response to damaged neurons, creating a vicious cycle that speeds up brain cell degeneration. In early experiments, antibodies that blocked GPNMB stopped the toxic process from spreading between cells.
New laser heat treatment could stop blindness before it starts
A new experimental treatment could finally offer hope for millions of people with dry age-related macular degeneration — one of the leading causes of blindness in older adults. Researchers at Aalto University discovered a way to gently heat tissue at the back of the eye using near-infrared light, triggering the cells’ natural “cleanup and repair” systems before major damage occurs.
Superintelligence: are we all doomed? With Nate Soares
Freddy Gray is joined by Nate Soares, president of the Machine Intelligence Research Institute, to discuss the risks posed to humanity by AI. Warning that sufficiently intelligent AI may stop following human instructions entirely, Soares tells Freddy what, if anything, could keep AI from spiralling out of control.
