The quantum teleportation allows one to teleport quantum information, but to fully recover it one needs to send 2 bits of classical information over a classical channel per each teleported qubit?
Quantum teleportation is a fundamental concept in quantum information theory that enables the transfer of quantum information from one location to another, without physically transporting the quantum state itself. This process involves the entanglement of two particles and the transmission of classical information to reconstruct the quantum state at the receiving end. In quantum teleportation,
Does the No-cloning theorem state that you cannot clone the basis states of the qubit?
The No-cloning theorem is a fundamental concept in quantum information theory that asserts the impossibility of creating an exact copy of an arbitrary unknown quantum state. This theorem has significant implications for quantum computing, quantum cryptography, and quantum communication protocols. To delve into the specifics of the No-cloning theorem, let us first understand the context

Should quantum measurement be made in a way not to disturb the measured quantum system?
Quantum measurement is a fundamental concept in quantum mechanics, playing a crucial role in extracting information from quantum systems. The question of whether quantum measurement should be made in a way not to disturb the measured quantum system is a central issue in quantum information theory. To address this question, it is essential to delve
