There indeed has been research on reversible adiabatic logic in superconducting electronics. But superconducting electronics has a whole host of issues of its own, such as low density and a requirement for ultra-low temperatures.

When I was at Sandia we also had a project exploring ballistic reversible computation (as opposed to adiabatic) in superconducting electronics. We got as far as confirming to our satisfaction that it is possible, but this line of work is a lot farther from major commercial applications than the adiabatic CMOS work.
