Nov 3 at 23:46 | comment | added | Daniel Hoekwater | - After the second Hadamard gate: $(|0\rangle \otimes (1+e^{i\theta_1})a|u_1\rangle + (1+e^{i\theta_2})b|u_2\rangle) + |1\rangle \otimes (1-e^{i\theta_1})a|u_1\rangle + (1-e^{i\theta_2})b|u_2\rangle)$ | |
Nov 3 at 23:46 | comment | added | Daniel Hoekwater | - After the controlled U: $(|0\rangle \otimes a|u_1\rangle + b|u_2\rangle) + (|1> \otimes e^{i\theta_1}a|u_1\rangle + e^{i\theta_2}b|u_2\rangle)$ | |
Nov 3 at 23:46 | comment | added | Daniel Hoekwater | - After the first Hadamard gate: $|+> \otimes a|u_1\rangle + b|u_2\rangle$ | |
Nov 3 at 23:46 | comment | added | Daniel Hoekwater | - Prior to the first gate: $|0> \otimes a|u_1\rangle + b|u_2\rangle$ | |
Nov 3 at 23:40 | comment | added | Daniel Hoekwater | Since we don't know how to express $a|u_1\rangle + b|u_2\rangle$ in the standard basis, I'm a little unsure how to properly track the state through each gate, but here's what I have so far: - Prior to the first gate: $|0> \otimes a|u_1\rangle + b|u_2\rangle$ | |
