Researchers achieve direct counterfactual quantum communication

Posted by in categories: particle physics, quantum physics

(—In the non-intuitive quantum domain, the phenomenon of counterfactuality is defined as the transfer of a quantum state from one site to another without any quantum or classical particle transmitted between them. Counterfactuality requires a quantum channel between sites, which means that there exists a tiny probability that a quantum particle will cross the channel—in that event, the run of the system is discarded and a new one begins. It works because of the wave-particle duality that is fundamental to particle physics: Particles can be described by wave function alone.

Well understood as a workable scheme by physicists, theoretical aspects of counterfactual have appeared in journals, but until recently, there have been no practical demonstrations of the phenomenon. Now, a collaborative of Chinese scientists has designed and experimentally tested a counterfactual communication system that successfully transferred a monochrome bitmap from one location to another using a nested version of the quantum Zeno effect. They have reported their results in the Proceedings of the National Academy of Sciences.

The quantum Zeno effect occurs when an unstable quantum system is subjected to a series of weak measurements. Unstable can never decay while they are being measured, and the system is effectively frozen with a very high probability. This is one of the implications of the well known but highly non-intuitive principle that looking at something changes it in the quantum realm.

Unbreakable quantum entanglement

Posted by in categories: particle physics, quantum physics, space

Einstein’s “spooky action at a distance” persists even at high accelerations, researchers of the Austrian Academy of Sciences and the University of Vienna were able to show in a new experiment. A source of entangled photon pairs was exposed to massive stress: The photons’ entanglement survived the drop in a fall tower as well as 30 times the Earth’s gravitational acceleration in a centrifuge. This was reported in the most recent issue of Nature Communications. The experiment helps deepen our understanding of quantum mechanics and at the same time gives valuable results for quantum experiments in space.

Einstein’s theory of relativity and the theory of are two important pillars of modern physics. On the way of achieving a “Theory of Everything,” these two theories have to be unified. This has not been achieved as of today, since phenomena of both theories can hardly be observed simultaneously. A typical example of a mechanical phenomenon is entanglement: This means that the measurement of one of a pair of light particles, so-called photons, defines the state of the other particle immediately, regardless of their separation. High accelerations on the other hand can best be described by the of relativity. Now for the first time, quantum technologies enable us to observe these phenomena at once: The stability of quantum mechanical entanglement of can be tested while the photons undergo relativistically relevant acceleration.

This AI Company Offers Cryogenic Freezing With Its Health Plan

Posted by in categories: biotech/medical, cryonics, employment, health, life extension, robotics/AI

Staff members who die will be put in cold storage until medical science can revive them.

Since congressional Republicans voted in a bill containing the Trump administration’s roll back of the Affordable Care Act, healthcare is once again a topic on everyone’s lips. In the absence of any universal healthcare scheme, employer-provided medical coverage is a crucial benefit for employees, tempting people to stay at jobs they might otherwise have left, or apply for positions they wouldn’t otherwise consider.

In the contest to attract new hires, tech companies often supplement already generous salaries with comprehensive benefit packages, and in this vein one company has hit on a novel idea: A health plan that covers its employees beyond death and into the realms of a speculative future rebirth.

Drug Discovery AI Can Do in a Day What Currently Takes Months

Posted by in categories: biotech/medical, robotics/AI

To create a new drug, researchers have to test tens of thousands of compounds to determine how they interact. And that’s the easy part; after a substance is found to be effective against a disease, it has to perform well in three different phases of clinical trials and be approved by regulatory bodies.

It’s estimated that, on average, one new drug coming to market can take 1,000 people, 12–15 years, and up to $1.6 billion.

Introducing Echo Show

Posted by in category: media & arts

Voice responses from Alexa are now enhanced with visuals and optimized for visibility across the room. Call or message your family and friends that also have an Echo or the Alexa App, get the news with a video flash briefing, see your Prime Photos, shop with your voice, see lyrics with Amazon Music, and more. All you have to do is ask.

Echo Show has eight microphones and beam-forming technology so it can hear you from across the room—even while music is playing. Echo Show is also an expertly tuned speaker that can fill any room with immersive audio powered by Dolby. When you want to use Echo Show, just say the wake word “Alexa” and Echo Show responds instantly.

The Ins and Outs of Cellular Senescence: Longevity Conference Paris

Posted by in categories: biotech/medical, life extension

On May 16-19th a longevity research conference is being held in Paris.

On May 16-19th renowned researchers and advocates of healthy life extension will gather in Paris to discuss recent breakthroughs in regenerative medicine. The conference organized by the International Cell Senescence Association (ICSA) “The Ins and Outs of Cellular Senescence: Understanding the Biology to Foster Healthy Aging and Suppression of Disease” will take place in the famous Pasteur Institute in Paris. In addition to the main conference, an open public event will be held on the afternoon of May, 19th: an international panel of experts in aging research under the lead of Eric Gilson (Ircan research institute on cancer and aging in Nice) will reveal what we know about biological aging today and what medicine can do to prevent age-related diseases.

The Four Technologies That Are Turning Our World Into the Future

Posted by in categories: computing, engineering, space travel

Each year, the world’s greatest innovators and inventors gather for the Edison Awards to celebrate “game-changing” developments in technology, engineering, marketing, and design. Here are just some of the innovations that are already transforming our world.

Each year, innovators from across the globe trade in their lab coats and laptops for ties and gowns to honor the nominees at the Edison Awards ceremony in New York City. Over the past three decades, the awards have highlighted the most innovative products and people in science. Last year’s honorees featured Alan Stern, Principal Investigator of NASA’s New Horizons mission to Pluto.
