A NAND gate doesn't erase information; you still have the inputs. In Quantum computers it's more a matter of "overwriting" a qubit with a new value.

- dreamcompiler 3y agoEvery gate that has more inputs than outputs erases information. (NOT gates don't erase information.) Quantum gates generally have the same number of outputs as inputs, so they don't erase.
