Current technology for building digital computers is predicted to reach its limit within the next 10 years due to the increasing miniaturization of digital components. By reaching sizes of a few nanometers, electrons stop behaving as particles and start behaving as waves, obeying essentially the principles of Quantum Mechanics, and effects such as interference, superposition and entanglement become dominant. The utilization of those effects allows more that just an evolution of the miniaturization process. It allows for a computational parallelism impossible to be obtained efficiently through classical computational methods or devices. Several algorithms utilizing such effects have been proposed and indicated that Quantum Computation is significantly more efficient at solving certain class of problems than classical computation. Actually, there is not yet any hardware (a quantum computer) able to compute a useful algorithm outside of research labs. A turn-around to that problem is to simulate the behavior of a quantum computer by a classical computer. There are, to this day, a number of quantum computer simulators available which, in general, use the quantum circuit model defined by Deutsch. Just a few of them are universal. We have developed a novel universal quantum circuit simulator, called Zeno, to the design and test of quantum algorithms. Zeno offers a set of features that engulfs most of the features presented by the other existing universal quantum circuit simulators and that also allows it to be used in the design and simulation of quantum channels.
