Abstract
An interesting question in the design of quantum computers is how to interact with the environment. As the environment adds decoherence (or noise) to the system, we usually seek ways to minimize the interaction. It is clear to us though, that although we can try to limit this interaction, there will always be some noise. On the other hand, the environment can be a source of fresh qubits, needed for the computation. Limiting the interaction with the environment might prevent us from using this resource. In this work we explore quantum systems which do not use fresh qubits, but rather have low noise rates (which are still constant), and show what computations are possible.
