- Why can't information (or just quantum info?) be destroyed, and what is it?
What is information? IIRC it has something to do with bits. What is quantum information? Can either be destroyed? Why (not)?
EPR said:Please provide a proper reference which states that information cannot be destroyed.
EPR said:If this were true, the quantum eraser experiment wouldn't be possible.
sayetsu said:What is quantum information?
sayetsu said:what are quantum states and unitarity? What do these words mean?
sayetsu said:Some, yes. More than the average bear.
sayetsu said:I've only encountered it academically in my college chem class.
Quantum information is a field of study that combines the principles of quantum mechanics and information theory to understand how information is stored, processed, and transmitted in quantum systems.
Quantum information differs from classical information in that it is not limited to binary states (0 and 1) but can exist in multiple states simultaneously. This is known as superposition and is a fundamental property of quantum systems.
The principle of indestructibility in quantum information states that quantum information cannot be destroyed or lost, even if the physical system that carries it is destroyed. This is due to the phenomenon of entanglement, where particles are connected in such a way that the state of one particle is dependent on the state of the other, regardless of distance.
Quantum information has many potential applications in technology, such as quantum computing, quantum cryptography, and quantum sensors. These technologies utilize the unique properties of quantum systems to perform tasks that are not possible with classical systems.
One of the biggest challenges in studying and utilizing quantum information is the fragile nature of quantum systems. They are easily affected by external factors, making it difficult to maintain and manipulate their state. Additionally, the principles of quantum mechanics can be counterintuitive and require a different way of thinking compared to classical systems.
