For the quantum Fourier circuit, we have with n the number of qubits. For example, the Fourier circuit of 2-qubits:

For the quantum phase estimation, we have which takes two input arguments: a unitary operator U, and an integer n. The integer n specifies the number of qubits and operators in the circuit, with j=0,1,…,n-1. The accuracy of phase estimation and the success probability depends on n.

Given a graph, the corresponding circuit (which generates quantum graph/cluster states) is a series of controlled-Z operators on edges of graph:

For the Bernstein–Vazirani algorithm, one needs to specify a secret string bit as s as follows: for the oracle we have , and for the whole circuit e . For example, the Bernstein–Vazirani oracle for the secret bit of 101:
QuantumCircuitOperator[{BernsteinVaziraniOracle,s}]
QuantumCircuitOperator[{BernsteinVazirani,s}]
In[1]:=
| QuantumCircuitOperator |
Out[1]=

Boolean oracle for a given Boolean function:
One can also get the decomposition of a Boolean oracle, in terms of CNOTs and Z-rotation:
For the diffusion part of the Grover circuit (also called, the amplification part), one only needs to specify the number of qubits:
Another way of storing the solution of a Boolean function is to save it as a phase, rather than on an ancillary qubit. This can be archived by using a phase oracle, that add an overall phase of π if the quantum state is a solution of the Boolean function.
The corresponding diffusion part, given a phase oracle:
One can also create the overall Grover circuit, using controlled-1 gates and a Boolean oracle:
One can also create the overall Grover circuit, using controlled-0 gates and a Boolean oracle:
One can also create the overall Grover circuit, using controlled-1 gates and a phase oracle:
One can also create the overall Grover circuit, using controlled-0 gates and a phase oracle:
One can find Trotter-Suzuki decomposition, to approximate a time evolution.
