Reversible logic has applications in low-power computing and quantumcomputing. However, there are few existing designs for reversiblefloating-point adders and none suitable for quantum computation. In this paperwe propose a space-efficient reversible floating-point adder, suitable forbinary quantum computation, improving the design of Nachtigal et al. Our workfocuses on improving the reversible designs of the alignment unit and thenormalization unit, which are the most expensive parts. By changing a fewelements of the existing algorithm, including the circuit designs of the RLZC(reversible leading zero counter) and converter, we have reduced the cost about68%. We also propose fault-tolerant designs for the circuits. The KQ for ourfault-tolerant design is almost sixty times as expensive as for a 32-bitfixed-point addition. We note that the floating-point representation makesin-place, truly reversible arithmetic impossible, requiring us to retain bothinputs, which limits the sustainability of its use for quantum computation.
