How does the quantum measurement work as a projection?
In the realm of quantum mechanics, the measurement process plays a fundamental role in determining the state of a quantum system. When a quantum system is in a superposition of states, meaning it exists in multiple states simultaneously, the act of measurement collapses the superposition into one of its possible outcomes. This collapse is often

Realism means that all physical quantities have their values determined before the measurement?
Realism in the context of quantum mechanics refers to the philosophical viewpoint that physical quantities possess definite values independent of measurement. This concept has been a subject of intense debate, especially in the realm of quantum information theory, where phenomena such as quantum entanglement challenge classical intuitions about the nature of reality. According to classical

What does it mean for two spatially separated systems to be inside the locality limits?
In the realm of Quantum Information, the concept of locality plays a pivotal role in understanding the behavior of quantum systems. When two spatially separated systems are said to be inside the locality limits, it refers to the principle that the measurements or interactions on one system should not have an instantaneous effect on the
