Quantum logic gate by Ciro Santilli 37  Updated 2025-05-26  +Created 1970-01-01

At Section "Quantum computing is just matrix multiplication" we saw that making a quantum circuit actually comes down to designing one big unitary matrix.
We have to say though that that was a bit of a lie.
Quantum programmers normally don't just produce those big matrices manually from scratch.
Instead, they use quantum logic gates.
The following are the main reasons for that:
  • Section "Quantum logic gates are needed because you can't compute the matrix explicitly as it grows exponentially"
  • Section "Quantum logic gates are needed for physical implementation"
