Question

More on tensor products

Answer 1

?

Answer 2

two kets with unknown coefficients\[|\phi\rangle=(\alpha_0|0\rangle+\alpha_1|1\rangle)\]\[|\psi\rangle=(\beta_0|0\rangle+\beta_1|1\rangle)\]their tensor products are\[|\phi\rangle\otimes|\phi\rangle=(\alpha_0|0\rangle+\alpha_1|1\rangle)(\alpha_0|0\rangle+\alpha_1|1\rangle)\]\[|\psi\rangle\otimes|\phi\rangle=(\beta_0|0\rangle+\beta_1|1\rangle)(\alpha_0|0\rangle+\alpha_1|1\rangle)\]

Answer 3

Hi Turing Are you still in Mexico?

Answer 4

why is it that the inner product of those two tensor products is\[\langle\phi|\psi\rangle^2=\langle\phi\phi|\psi\psi\rangle\]????

Answer 5

nevermind, problem solved :)
