Summary

  • The importance of circuit identities Grover’s search algorithm is one of the first and most prominent examples to show how a quantum circuit can be magnitudes faster than a classical algorithm.
  • Of course, qubits are the computational unit we work with.
  • It is the task of the diffuser to magnify the amplitude to favor the searched state.
  • Image by author, Frank Zickert We end up with our qubit in the desired state |1⟩ because the Hadamard gate turns the state |−⟩ into |1⟩.
  • The following figure depicts the rotations we apply in this circuit.
