We talk a lot about quantum computation and quantum key distribution here at Ars, but when we do this, we're usually talking about a discrete logic system. That is, the quantum system uses a set of ...

Have you ever heard the person who talks about the weather on TV say that the weather is going to be variable close variableA named piece of data (often a number or text) stored in a computer’s memory ...

Variables are introduced using the example of a squirrel who wants to know where his nuts are buried, and how many he has. A variable is described as a special box where computers keep useful ...

The field of quantum information processing aims to harness the uniquely non-classical features of quantum mechanics to perform computational tasks that surpass classical capabilities. In continuous ...

Every twenty to twenty-five years, trends and fads start reappearing. 2016 is shaping up to be a repeat of 1992; the X-files is back on the air, and a three-way presidential election is a possibility.

Continuous variable quantum information technology can provide an equivalent to analog data in the quantum world. Researchers are now demonstrating that it's possible to use these systems to avoid ...
