A single photon reveals quantum entanglement of 16 million atoms

Posted by in categories: encryption, quantum physics

Quantum theory predicts that a vast number of atoms can be entangled and intertwined by a very strong quantum relationship, even in a macroscopic structure. Until now, however, experimental evidence has been mostly lacking, although recent advances have shown the entanglement of 2,900 atoms. Scientists at the University of Geneva (UNIGE), Switzerland, recently reengineered their data processing, demonstrating that 16 million atoms were entangled in a one-centimetre crystal. They have published their results in Nature Communications.

The laws of allow immediately detecting when emitted signals are intercepted by a third party. This property is crucial for data protection, especially in the encryption industry, which can now guarantee that customers will be aware of any interception of their messages. These signals also need to be able to travel long distances using special relay devices known as quantum repeaters—crystals enriched with rare earth and cooled to 270 degrees below zero (barely three degrees above absolute zero), whose atoms are entangled and unified by a very strong quantum relationship. When a photon penetrates this small crystal block, is created between the billions of atoms it traverses. This is explicitly predicted by the theory, and it is exactly what happens as the crystal re-emits a single photon without reading the information it has received.

It is relatively easy to entangle two particles: Splitting a photon, for example, generates two that have identical properties and behaviours. Florian Fröwis, a researcher in the applied group in UNIGE’s science faculty, says, “But it’s impossible to directly observe the process of entanglement between several million atoms since the mass of data you need to collect and analyse is so huge.”

Beaming laser power to ion drive is 300–400 times more thrust than just laser photonic sail

Posted by in category: space travel

A 100 meter to 150 meter solar array that is attuned to the lithium ion will be about 70% efficient.

JPL is working on the gridded lithium ion arrays to achieve 60,000 ISP.

There is work on 60 meter deployable solar arrays.

Toyota’s Trucks That Only Emit Water Vapor Are Moving Goods in LA

Posted by in categories: energy, transportation

Japanese automaker Toyota is serious about perfecting hydrogen fuel cell technology to power its vehicles, and it’s scheduled an initial feasibility study operations for its zero-emissions heavy-duty truck a little over a week from today. A concept version of a truck running Toyota’s specialized hydrogen fuel cell system designed for heavy-hauling use will be moving goods from select terminals at the Port of LA and Long Beach to nearby warehouses and rail yards beginning on October 23.

“If you see a big-rig driving around the Ports of Los Angeles and Long Beach that seems oddly quiet and quick, do not be alarmed! It’s just the future,” Toyota wrote in a press release. The company expects the daily runs to cover some 322 kilometers (200 miles) to test the fuel cell system’s duty-cycle capabilities. Afterwards, longer trips could be introduced.

A knock off of Boston Dynamics dog robot, but interesting to see. I’d be curious how loud it is, you know it’s usually pretty loud when there’s no audio.

Stem Cell Primer What You Need to Know

Posted by in categories: biotech/medical, futurism

First article (#1 of 3) in three part stem cell series.


Summary: A brief tutorial on the science behind stem cell therapy.

Doctors already use stem cells to treat blood diseases, a cell-based therapy that has saved the lives of thousands of children with leukemia. Additionally, physicians used stem cells to successfully treat some types of bone, skin, and eye injuries and diseases. The potential of stem cell therapies is enormous, and some researchers feel that we will be able to regrow organs in the near future.

Cellular Garb-aging Causes You To Age (Loss of proteostasis)

Posted by in categories: biotech/medical, life extension

Cellular Garb-aging is the build-up of junk inside the cells that naturally occurs during aging. This article says why it happens.


To maintain protein homeostasis, and prevent garb-aging, the cell uses molecular chaperones, which help assemble and disassemble proteins. Chaperonins are a special class of chaperones that provide favorable conditions for the correct folding of other proteins, thus preventing aggregation. Chaperonins prevent the misfolding of proteins, which prevents conditions such as Mad Cow Disease. Sometimes, chaperonin proteins may also tag misfolded proteins to be degraded. When properly tagged, other processes can recognize the damaged or misfolded proteins and ‘take out the trash.’

Think of it as garb-aging removal.

Why Inflammaging Causes Disease and Premature Aging

Posted by in categories: biotech/medical, life extension, neuroscience

Researchers have discovered why inflammaging occurs and are working on new treatments. Inflammaging is new medical term for “the chronic inflammation brought on by old age.”


Summary: Inflammaging is a low-grade inflammation brought on by old age. It accelerates the aging process and worsens diseases like cancer and heart disease. Because inflammaging accelerates aging, geroscientists are perfecting a few cures for the condition.

As we age, most of us tend to develop a low-grade chronic inflammation that causes disease and damage throughout the body. Because this low-level inflammation typically accompanies aging, scientists have nicknamed it ‘inflammaging.’ Most geroscientists implicate inflammaging as the cause of many of age-related diseases including diabetes, heart disease, cancer, and dementia. These chronic diseases accelerate aging and shorten our lives.
