Quantum Entanglement and Teleportation

Teleportation! You’ve seen it in the movies and the books. It seems supernatural, almost a myth, maybe. But, this teleportation idea doesn’t seem that unbelievable anymore. A concept called quantum entanglement is directly related to teleportation.  Quantum entanglement, simply put, is like a connection between two particles far away from each other. Though it is not teleportation, we can use this idea for teleportation in the future, solving many of our world’s problems.

Quantum entanglement first requires a connection between two particles. This means when one particle is being conversed about/used, the second particle must be directly influenced in precisely the same way, as they are entangled with one another. This gives these particles the connection we are talking about. Let us say that we turn one particle 180 degrees clockwise. Another particle, which is quantum entangled with the first particle will also turn 180 degrees clockwise. Pretty freaky, right? Even when two entangled particles are separated by long distances, they are still entangled, letting them “communicate” across fairly long distances, maybe even infinite. To clarify, we do not know yet how far quantum entanglement can occur. It can be across a stretch of light years, galaxies even, as we haven’t found any limit to this idea.

Quantum entanglement can easily solve many of the worlds problems. Most importantly, quantum entanglement can help us discover teleportation. With teleportation, we can solve problems of insufficient medical supplies, slow emergency vehicles, insufficient clean water, and even poverty, to name a few. For insufficient clean water, we can send these countries water from countries which have sufficient water, such as the U.S. and England. The U.S. can even ship medical supplies to third-world countries. This quantum entanglement can also help our expansion in space. We can send fresh food to astronauts, which can slow the deterioration cycle of being in space. Lots of problems can be solved using teleportation coming from quantum entanglement, but there is still a ways to go before this happens.

Though we may not be too far in the art of teleportation, scientists across the world have made many recent developments in quantum entanglement. According to a recent study,

In 2016 physicists Ryo Okamoto and Shigeki Takeuchi of Kyoto University verified Aharonov and Vaidman’s predictions experimentally using a light-carrying circuit in which the shutter photon is created using a quantum router, a device that lets one photon control the route taken by another.

Another instance is where a group of Chinese scientists packed 18 qubits—the most basic units of quantum computing—into just six weirdly connected photons using quantum entanglement.

The most thrilling situation, however, is where another group of Chinese scientists broke a record by sending a packet of information from Tibet to a satellite in orbit, up to 870 miles (1,400 kilometers) above the Earth’s surface, using quantum entanglement. These discoveries show much promise, but there are still some unanswered questions surrounding them.

The problem with these experiments is we don’t know if it is the same photon on the other side. If you teleport an object, there is doubt whether it is the same object after being teleported–is it actually the original or just a convincing copy? So, instead of teleporting, we could just be copying molecules from one place to another. Today, scientists are still working on what really goes on during teleportation and quantum entanglement.

As you can see, teleportation doesn’t seem an impossible idea anymore. We are already advancing into the use of quantum entanglement, and finding the key to quantum entanglement allows us to go even farther with the idea of teleportation. This idea can help everyone, as supplies all around the world can be sent so much faster than modern transportation, along with many other benefits to our society. But, there is still a lot of mystery to solve for scientists as what exactly happens to the particles during quantum entanglement. So, there may be awhile before we get into the idea of teleporting humans from LA to Tokyo, but are closer than ever, and quantum entanglement is the way to reaching that goal.

MIT Discovers New State of Matter and Magnetism

I know we all learned in chemistry class that the basic building blocks of the ‘matter syndicate’ are solid, liquid, gas, and plasma, but it appears there’s a new player in town; his name is ‘quantum spin liquid.’

There are in fact many different states of matter that you’ve either never heard of, or didn’t realize was considered a different state of matter, ie. glass, or ferromagnets.

The specific quantum spin liquid that researchers at MIT have discovered is called herbertsmithite, named after, well, I’m sure you can figure that out. Quantum spin liquids, or QSLs, have a very strange type of magnetism.  Unlike the magnets you stick on your refrigerator, the electrons in a QSL don’t all align with the same orientation.  In fact, the internal magnetism of a QSL is constantly fluctuating.  Herbertsmithite is a solid crystal, but the magnetism is in constant motion like a liquid.   Despite the constant fluctuations of the magnetic orientation of the electrons in the QSL, there is a strong connection between all of the electrons, allowing this specific type of matter to have what it takes to be used in long rang quantum entanglement.

So what does that mean for us harebrained civvies?  According to Young Lee, the head researcher of the discovery, this means:

…advances in data storage or communications, perhaps using an exotic quantum phenomenon called long-range entanglement, in which two widely separated particles can instantaneously influence each other’s states. The findings could also bear on research into high-temperature superconductors, and could ultimately lead to new developments in that field.

Did I just hear instantaneous long range communication, infinite cloud storage, and flying cars?  Yes’m.

The truth is that this discovery will likely involve unimaginable implications.

Lee explains that:

We have to get a more comprehensive understanding of the big picture.  There is no theory that describes everything that we’re seeing.

In the last decade humanity has entered the wild, wild west of the quantum future. Herbertsmithite may very well be the trusted six shooter we’ve been waiting for.

Electronic Brain Implants Increase Intelligence

Scientists have successfully improved the thinking ability in primates through an electronic brain implant in the cerebral cortex. The decision making abilities of the primates were restored, and in many cases improved.

The scientists trained rhesus monkeys over the course of two years to gain a 75% efficiency in a basic image matching game. After mapping the monkeys’ brains with probes in the cerebral cortex, the began step two.

They got the monkeys cranked up on cocaine.  No, seriously.  While under the effect of the cocaine, the monkeys’ score on the matching game dropped by 20%. But, by stimulating the correct neurons with the probes, the monkeys’ scores returned to the 75% level. When the scientists activated the probes under normal conditions, the scores improved to unprecedented levels.

Scientists believe this is the beginning of  truly and permanently helping victims of brain trauma return to their previous selves.  It could also lead to hyper intelligent humans.

Don’t be surprised if newborns start explaining quantum entanglement to their parents.  That’s just the implants doing their job.

Long Distance Quantum Teleportation is Reality

Researchers in multiple locations around the globe have successfully teleported photons across distances greater than 100km. We aren’t ready to beam people up to the moon for a gravity-free lunar getaway just yet, but these recent breakthroughs are a monumental step in the right direction.

Just weeks after researchers in China quantumly teleported photons a distance of 100km, researchers from the University of Waterloo completed a similar teleportation near the Canary Islands over a distance of 143 km.

The technique used isn’t teleportation in the traditional Star Trek sense, it is an implementation of quantum entaglement. The photon being teleported isn’t moved anywhere. Essentially, its information is copied perfectly and instantaneously to another photon at an intended destination.  Quantum entanglement allows us to send and receive information without any error or delay whatsoever.

Using a new laser technology that ensures the laser beam remains focused and does not disperse, scientists are paving the way for a global quantum network, the next evolutionary step of the internet.  A quantum network “could form the backbone of an internet populated by quantum computers. In theory, each quantum processor/computer connected to the quantum network could be instantly linked to every other computer via an entangled pair of photons.”

Quantum teleportation also redefines privacy.  Because it is impossible to view an entangled particle, information that is entangled would be protected and guaranteed to be 100% secure.  Quantum cryptography will replace password protection in the future.

In lieu of recent breakthroughs, Kirk’s classic catchphrase may need to be changed;  “Entangle me up Scottie!”
