Quantum Entangled Emitter and Receiver

In summary, the conversation discusses the concept of using entangled particles for instantaneous transfer of data. However, it is explained that this is not possible as the other person would only receive a random bit and there is no way to discover the entanglement until both parties compare notes. This idea may have potential problems and limitations.

Hello fellow science enthusiasts.
The other day I was thinking of a device for instantaneous transfer of data. You would have two entangled particles (or any even number but two just for simplicity), then you would "put" each one in two devices. An input is needed. For example a simple message in binary saying "Test 123". The message would be indeed made up of ones and zeros. That would be then recognised by another device as each 1 or 0 is an instruction. For example a one would turn on a magnetic field to rotate the particle so it is pointing up and a 0 pointing down with a neutral state or rest position being pointing to the middle. Now I know up, down and middle are not specific directions but just imagine them as relative ones. If I am correct that would mean the other particle would experience the same effect and the up or down will be detected by a device with exact recognition of what each state is and it would translated into ones and zeros. That would then be put together to form a bunch of ones and zeros which would go into a output of some sort which will then translate the binary into "Test 123". This is just to begin with, you could speed up the process with more data being sent to maybe even form a picture and later on, a live video feed.

Now I know this is all just something I thought about which will at least, have some problems to begin with. To start, I don't even know if it's actually possible to use a small magnetic field on an entangled particle without disrupting the entanglement, in other words, breaking the bond. I just wanted to know if it's possible. If it was, it could mean a communication latency would be very little (even on an interstellar or intergalactic scale)

Many thanks,

Sorry - entanglement doesn't work that way.

No matter what you do to your particle, if the other guy makes either a left-right or an up-down measurement, he'll get a random bit.

There's no way of even discovering that any entanglement was going on until you and the other guy get together and compare notes. Then you'll discover that, for every particle pair, if you had both measured up-down or you both had measured left-right you always got opposite answers; if one of you measured left-right and the other up-down the results were completely uncorrelated.

Thanks for clearing up the confusion :)
 

1. What is a Quantum Entangled Emitter and Receiver?

A Quantum Entangled Emitter and Receiver is a technology that allows for the transmission of quantum information between two distant objects instantaneously, regardless of the distance between them. This is made possible through the phenomenon of quantum entanglement, where two particles become connected in such a way that the state of one particle affects the state of the other, even when they are separated by vast distances.

2. How does Quantum Entanglement work?

Quantum Entanglement works by creating a pair of particles that have opposite properties, such as spin or polarization. These particles are then separated, but their states remain connected. When one particle's state is changed, the other particle's state is also changed, no matter how far apart they are. This allows for the transmission of information between the particles instantaneously, making it faster than the speed of light.

3. What are the potential applications of a Quantum Entangled Emitter and Receiver?

There are a variety of potential applications for a Quantum Entangled Emitter and Receiver, including secure communication, quantum teleportation, and quantum computing. With secure communication, the transmission of information through quantum entanglement would be unhackable, providing a new level of security for sensitive data. Quantum teleportation could also be achieved by using entangled particles to transmit the quantum state of an object, allowing for the creation of a replica at a distant location. Lastly, entanglement is a crucial component of quantum computing, allowing for faster and more powerful processing capabilities.

4. What are the challenges of using Quantum Entanglement in technology?

One of the main challenges of using Quantum Entanglement in technology is maintaining the entanglement over long distances. The state of entangled particles can be easily disrupted by outside interference, making it difficult to transmit information reliably. Additionally, the technology required to produce and detect entangled particles is complex and expensive, making it a challenge to implement on a large scale.

5. Are there any ethical concerns surrounding the use of Quantum Entanglement?

There are some ethical concerns surrounding the use of Quantum Entanglement, particularly in regards to its potential use in secure communication and surveillance. The ability to transmit information instantaneously and without detection could raise concerns about privacy and government control. Additionally, the development of quantum computing through entanglement could potentially lead to a significant power imbalance in technology and data control. It is important to carefully consider the ethical implications of this technology as it continues to advance.
