Molyneux was known popularly known as a mathematician and maker of mathematical instruments such as compasses and hourglasses. He became acquainted with many prominent men of the day, including the writer Richard Hakluyt and the mathematicians Robert Hues and Edward Wright. He also knew the explorers Thomas Cavendish, Francis Drake, Walter Raleigh and John Davis. Davis probably introduced Molyneux to his own patron, the London merchant William Sanderson, who largely financed the construction of the globes.

莫利纽克斯最初是作为一名数学家和制作诸如圆规和沙漏这样的数学仪器而被人所知，他与当时的很多社会名流都有来往，包括作家理查德·哈克卢特，数学家罗伯特·休斯和爱德华·赖特，他还认识探险家托马斯·卡文迪什，弗兰西斯·德雷克，约翰·戴维斯，戴维斯很可能将莫利纽克斯介绍给了他的资助人，伦敦商人威廉·桑德森，而他对莫利纽克斯制作球仪提供了大量的资助。

Quantum cryptology is a new method for secret communications. Compared to the classical cryptography, the greatest advantages of quantum cryptography are provable security and detectives; this is because the security of quantum cryptography is ensured by quantum no-cloning and Heisenberg's uncertainty principle that instead of relying on some complex mathematical problems.

量子密码技术是一种实现保密通信的新方法，它比较于经典密码的最大优势是具有可证明安全性和可检测性，这是因为量子密码的安全性是由量子物理学中量子不可克隆性和Heisenburg测不准原理来保证的，而不是依靠某些难解的数学问题。
