Quantum-computing technology is currently being used to encrypt data, but it holds a lot more potential than that, if only because of its massive information-storage capacity. One of the marvelous little wrinkles of the quantum world is a condition known as superposition, in which a particle can occupy two states at the same time. (Don't ask; it just can.) For this reason, a quantum bit, or qubit, can store two numbers at once. Each qubit added to a quantum computer doubles the size of the system, so if you want to know the capacity of a computer...
...used purely technological approaches to fight piracy, such as restricting the operation of peer-to-peer applications” that allow students to download files illegally. Levine said he also opposed this option, noting that many peer-to-peer applications were difficult to find because they often encrypt their traffic. And some peer-to-peer programs, he added, are used for “perfectly legal purposes.” —Staff writer Alaxander B.Cohn can be reached at abcohn@fas.harvard.edu

...short for Secure Socket Layer, is used to encrypt information sent over the Internet. While most e-mail is not encrypted, SSL is commonly used by bank websites, websites processing credit card transactions, and Harvard PIN websites...
...users are sufficiently disgruntled to the point that they would do so if they knew this clause was present, we’ve already established that most users almost certainly haven’t read the terms of service to begin with. It’s possible to encrypt AIM conversations so that AOL can’t intercept them, but to do so requires both parties to commit and requires a certain level of technological proficiency which the typical AIM user doesn’t possess...
