Use and benefits of quantum entanglement

Quantum entanglement is a phenomenon in quantum physics where two or more particles can be correlated in a way that the state of one particle cannot be described independently of the other(s), even if the particles are separated by a large distance. This property has the potential to bring about many benefits in the future, particularly in the fields of communication, computing, and cryptography.

  1. Communication: Quantum entanglement can be used to establish secure communication channels that are resistant to eavesdropping. This could have applications in areas such as secure financial transactions, military communications, and other sensitive information transfers.
  2. Computing: Quantum computers leverage the properties of quantum entanglement to perform certain calculations much faster than classical computers. This could lead to breakthroughs in areas such as cryptography, simulations, and optimization problems.
  3. Cryptography: Quantum key distribution (QKD) uses quantum entanglement to generate a secure key for encrypting and decrypting messages. QKD is believed to be secure against all known forms of eavesdropping, making it a promising solution for secure communications.
  4. Sensing: Quantum entanglement can also be used for highly sensitive measurements in fields such as biology, chemistry, and physics.

It is important to note that while the potential benefits of quantum entanglement are significant, realizing these benefits will require substantial technological and scientific advances. Additionally, the development of practical applications of quantum entanglement is still in its early stages, and it will likely take several years before these technologies become widely adopted.

Now, the reality: As per Communication

First, it has been speculated that the speed of entanglement is 10,000 times the speed of light, often denoted as 10,000c. In my opinion, it could very well be billions of times the speed of light. While it hasn’t been definitively demonstrated or proven, there is a consensus that the speed of entanglement is indeed faster than light.

Secondly, the reason we cannot “hop” off the entanglement phenomenon for communication is that we cannot control the state of entangled particles. Two entangled particles exist in every possible state simultaneously until observed. Once observed, the state of particle A is randomly set, and particle B instantly assumes the opposite state, whether it has been observed or not. Once either particle A or B, or both, have been observed or monitored, their states are set and cannot be changed, manipulated, or used again. *&?@!*, and I thought quantum entanglement would be easier to grasp!

If you’re losing sleep trying to understand this as I am, here’s a pretty good video from the Cool Worlds YouTube channel. The video explains why the speed of entanglement is fascinatingly rapid and also delves into the reasons we can’t utilize it just yet.
