No, when quantum entangled particles interact with their surroundings or other particles, their entanglement can be disrupted or altered. This is a fundamental characteristic of entanglement in quantum mechanics. Entanglement is a delicate and non-classical correlation between particles, where the state of one particle is intrinsically linked to the state of another, regardless of the distance between them.
When entangled particles interact with their environment or other particles, they can become entangled with additional degrees of freedom, leading to a process called entanglement decoherence. Decoherence occurs when the entangled particles become entangled with a large number of uncontrollable degrees of freedom in their surroundings, such as thermal vibrations or electromagnetic fields. As a result, the entanglement between the original particles is disrupted, and they become effectively disentangled.
The process of entanglement decoherence is a major obstacle in the practical implementation of quantum information processing and quantum communication systems. Researchers are actively studying methods to mitigate or control decoherence effects, such as isolating the system from external influences or employing error-correction techniques.
In summary, the interaction of entangled particles with their surroundings or other particles can disrupt their entanglement, leading to entanglement decoherence. Maintaining and protecting quantum entanglement is a significant challenge in the field of quantum information science.
