I'm constructing a quantum circuit that implements a gray code that connects the binary strings |0001> and |1110> using CNOT gates. Since the two strings are negations of each other, two equivalent circuits can be designed where the control qubit conditions are negated. My question is what is more efficient/ easier to construct: a CNOT where control qubit is set if it equals 0 or one where its set if it equals 1?(adsbygoogle = window.adsbygoogle || []).push({});
