The Quantum Internet is Born
“Years from now it may be said that the quantum Internet was born today.” Of course, the quantum internet is just in the baby stages now - but when it matures, it will be able to process ridiculous amounts of data at blaring speed, and never be hacked. The system, developed by physicists Stephan Ritter and Gerhard Rempe at the Max Planck Institute of Quantum Optics in Germany, has two nodes. Although this is small, the internet you’re on right now started in the 1960s in a similar process.
This first quantum network was built by utilizing two atoms of rubidium which exchange photons. Each atom is placed inside an individual ‘room’ with highly reflective mirrors surrounding it, and at a short distance from its sister atom. These rooms, called optical cavities, are connected by an optical fiber.
First, scientists aim a laser at the first rubidium atom, which induces an emission of a single photon. That photon travels along the optical fiber to the other optical cavity, containing the other atom. Thanks to the mirrors, the photon bounces off the mirrors thousands of times, and is absorbed by the atom upon collision. This absorption transmits information about the first atom’s quantum state - and voila, a transfer of information.
The two rubidium atoms were entangled beforehand, which effectively means that they were linked together. During entanglement (read more about entanglement here), certain properties of the atoms are linked, and measuring one instantaneously produces the same result in the other atom. During this experiment, the atoms were entangled for 100 microseconds - a long time in quantum physicists. Entanglement what renders any form of hacking impossible - as soon as a would-be hacker tapped into the quantum network, the quantum states of the atoms would no longer match up.
This is the first step towards something great.
I love physics
Interviewer: And we’re hoping that at some point we can get rid of the hungry and sleepy problem.
Jason Silva: Exactly, because that’s really the point, right? We want to transcend our biological limitations. We don’t want biology or entropy to interrupt the ecstasy of consciousness. Consciousness, when it’s unburdened by the body, is something that’s ecstatic; we use the mind to watch the mind, and that’s the meta-nature of our consciousness, we know that we know that we know, and that’s such a delicious feeling, but when it’s unburdened by biology and entropy it becomes more than delicious; it becomes magical. I mean, think of the unburdening of the ego that takes place when we watch a film; we sit in a dark room, it’s sort of a modern church, we turn out the lights and an illumination beams out from behind us creating these ecstatic visions. We lose ourselves in the story, we experience a genuine catharsis, the virtual becomes real—-it’s total transcendence, right?Right.
Silva: But then think of being in the movie theater and you have to pee, or you have a headache, or you ate too much for lunch before the movie and you’re being weighed down by your metabolism. This is biology getting in the way of the potential that consciousness has to experience these heightened states. So you have this interesting thing happening where biology is this emergent phenomenon that builds upon its own complexity, and it leads to the emergence of consciousness, but then consciousness wants to free itself from constraints that biology sets forth. So even though biology causes consciousness, it also burdens it.
This guys mind is amazing
oh how i wish life was simple as the cartoons we watch
Has Science Found the First “White” Hole?
A white hole is a theoretical beastie that exists as a set of equations that were a by-product of Einstein’s theory of relativity. It is basically a black hole in reverse. If a black hole is an object from which nothing can escape, then a white hole is an object into which nothing can enter—it can only radiate energy and matter.
