Two clouds of super cool Bose Einstein condensate have been successfully entangled. A first in the world of alternative matter.
There are two main branches of physics. Conventional Relativity – which is concerned with the macroscopic world, and Quantum Physics which originally attempted to explain the strange behavior of microscopic reality below planck distance – the minimum “pixel size” of conventional relativity where things transform in to the quantum foam.
Originally we observed that electrons on one side of an atom would always spin opposite to their “entangled” partner on the other side (See Quantum Chemistry). Then we discovered the same phenomena applies to photons – when light is shot through a crystal photons become entangled. No matter how far they go after the original crystal powered entanglement if you change the direction of one of them the other follows suit.
extreme temperatures can transform the distance at which quantum rules take over – creating entirely new forms of matter from super cool atomic clouds. A Bose Einstein Condensate the most well known alternate state of matter in this case.
Now we’re finding that the polarity of entire atoms and molecules can also be entangled. This type of non-local interaction is a distinguishing feature of quantum physics. Now with the most recent discoveries quantum rules continue to encroach upon sizes that were originally considered only the domain of conventional relativity.
Only recently have we begun to apply this thinking to a new wave of Technologies including radars, clocks, and radios that use fluctuations at the molecular, atomic and subatomic scale to perform useful operations.
In other word scientists, engineers and computer scientists are figuring out how to encode atomic pairs with a particular rythym of “spin flip” by adjusting the amplitude and direction of a pulsing electromagnet.
That starts with shooting a laser beam through a crystal to create an entangled light wave and then depending on what strange states of matter they choose for the computer a certain number of entangled photon pairs can be programmed to sustain a type of non-local circuit board strung across space and time.
The wavelike nature of quantum mechanics allows for instantaneous information transmission, in other words, akin to machine learning, quantum computers will comunicate across different platform and learn from one another but in adittion to that the information is processed at speeds the trump every supercomputer on the planet.
In order to hack a quantum computer you would have to observe the encrypted light waves. Upon observations wave of lights collapse in to a photon dissolving whatever connection remains between the hacker and target. So along with super fast complex processing quantum computing offers truly secure communications as far as we know so far.
Researchers cooled a gas to temperatures approaching Absolute Zero
When they are restricted to a small volume super cool gas atoms become indistinguishable from one another forming the alternate state of matter known as a Bose Einstein Condensate.
They released the cloud from it’s magnetic trap and used a laser beam to part the Condensate into separate formations, then using high resolution imaging to measure it they found that entanglement between the two clouds persevered.
Programming two entire clouds of Bose Einstein Condensate could herald a huge advancement in terms of qubit capacity. Where the current record for entangled functioning units is 72 qubits i.e. 72 pairs of 144 particles according to Google (20 proven in a lab), scientists claim that this discovery could lead to the entanglement of a thousand or more “qubits”.
We used spin mixing in a tightly confined Bose-Einstein condensate to generate an entangled state of indistinguishable particles in a single spatial mode. We show experimentally that this entanglement can be spatially distributed by self-similar expansion of the atomic cloud. We used spatially resolved spin read-out to reveal a particularly strong form of quantum correlations known as Einstein-Podolsky-Rosen (EPR
