WebQuantum carry-lookahead adder has already attracted some attention because of its low T-depth. Our work further reduces the overall cost by introducing a higher radix layer. By analyzing the performance in T-depth, T-count, and qubit count, it is shown that the proposed adder is superior to existing quantum carry-lookahead adders. http://vlsigyan.com/16-bit-carry-look-ahead-adder-verilog/
WebExplanation: To derive the two-level Boolean expression for the output carry C4 shown in the given four-bit adder with carry lookahead, we need to use the carry lookahead generator logic to determine the carry between the second and third stages of the adder, then use the carry output from the third stage to determine the carry output for the ...
