How the no-cloning theorem got its name

Comment on "How the No-Cloning Theorem Got its Name"

A review by A. Peres [quant-ph/0205076] appears recently. It is difficult to add something to such kind of fundamental themes, but here is briefly presented some ideas about challenges of the no-cloning theorem and imaginary modifications of quantum mechanics, that could make precise cloning possible.

伪随机态、不可克隆定理与量子货币

Pseudorandom States, Non-Cloning Theorems and Quantum Money

本文提出伪随机态概念，基于量子安全单向函数给出其高效构造，并利用不可克隆定理证明其不可复制性质，最终将其应用于构建私钥量子货币方案。

No-cloning implies unalterability of the past

A common way of stating the non-cloning theorem -- one of distinguishing characteristics of quantum theory -- is that one cannot make a copy of an arbitrary unknown quantum state. Even though this theorem is an important part of the ongoing discussion of the nature of a quantum state, the role of the theorem in the logical-algebraic approach to quantum theory has not yet been systematically studied. According to the standard point of view (which is in line with the logical tradition), quantum cloning amounts to two classical rules of inference, namely, monotonicity and idempotency of entailmen…

实验验证：若使用单次解密密钥加密，量子比特可以任意克隆

Experimental demonstration that qubits can be cloned at will, if encrypted with a single-use decryption key

该研究通过实验验证了在使用单次解密密钥加密的情况下，量子比特可以稳定克隆，修正了量子不可克隆定理的理解。
