Quantum dot computation is an alternative solution to the CMOS technology, which has the strength to increase the speed of computations and reduce the power while performing those computations as well as it reduces the area when compared to CMOS technology. To perform computations using quantum, we generate arithmetic circuits where code converters play a significant role. In this paper, we are discussing 2-, 3-, and 4-bit binary to gray code converters that are designed with a minimum number of qubits using 0.0251, 0.0382, 0.06 μ m 2 area respectively. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.Code convertersMajority gatesQCAQuantum technologyQubitXOR
