Algorithmic No Cloning Theorem Deepai No cloning theorem and related issues (lecture of the quantum information class of the master in quantum science and technology) géza tóth. Note however that the no cloning theorem makes no implications on approximate cloning; it only proves that per fect copies of a quantum state cannot be made. thus, in quantum cryptography there are still probabilistic techniques that can be used to estimate approximate copies of a state. No cloning theorem the no cloning theorem states that it is impossible to create a perfect copy of an unknown quantum state. let be a classical state set having at least two elements and let and be systems sharing the same classical state set . We provide an algorithmic variant to the no cloning theorem, by showing that only a small minority of quantum pure states can clone a non negligible amount of algorithmic information.

What Is No Cloning Theorem No cloning theorem the no cloning theorem states that it is impossible to create a perfect copy of an unknown quantum state. let be a classical state set having at least two elements and let and be systems sharing the same classical state set . We provide an algorithmic variant to the no cloning theorem, by showing that only a small minority of quantum pure states can clone a non negligible amount of algorithmic information. The study of ap proximate cloning is currently an active area of both theo retical and experimental research and is discussed in detail in the additional resources provided at the end of this quick study. The no cloning theorem reveals that complex information cannot be perfectly replicated across systems. this principle underpins biological reproduction, neural processing, and ai, driving evolution and creativity. Quantum cloning is impossible. this is good news for quantum cryptography: an eavesdropper cannot intercept a message, clone it, send a copy to the intended receiver and keep a copy without introducing errors. we will come back to quantum cryptography later in the course. Two proofs of the no cloning theorem [1,2] have been published in 1982, both triggered by a claim that the use of →entangled states would allow one to transmit information with superluminal.
