All computations can be done in a reversible way. The basic idea is that we can discard memories instead of erasing them, and that idea is coherent with physics and mechanism.
Because it is theoretically possible to do computations reversibly, doesn't mean that they are done that way. It is very difficult in practice, as the developers quantum computers have found. And even computations that are done reversibly in a quantum computer then do not come to definite results. We are not conscious of superpositions. So I stand by my point that consciousness is a classical phenomenon.
