Quantum entanglement is a phenomenon in which two or more particles become correlated in such a way that the state of one particle is dependent on the state of the other, regardless of the distance between them. However, while quantum entanglement allows for instantaneous correlation between particles, it does not provide a means for directly exchanging information.
The key concept to understand is that when two particles are entangled, their states are intrinsically linked, but this link does not convey information in a conventional sense. The entanglement itself is a fundamental aspect of quantum mechanics and does not allow for the transmission of information faster than the speed of light.
The process of extracting information from an entangled system requires measurements to be made on the particles. However, these measurements are probabilistic in nature and only provide random outcomes. Even if the measurement results from one particle are instantaneously correlated with the other due to entanglement, this correlation does not convey any meaningful information until the measurement results are communicated through conventional means, which are limited by the speed of light.
In essence, while quantum entanglement is a fascinating and non-intuitive property of quantum mechanics, it cannot be used for direct communication or the exchange of information beyond what can be achieved through classical means.
