How to check unitary matrix of quantum circuit?

How to check unitary matrix of quantum circuit?

We usually start all the qubits from 0 value and applying these quantum gates we finally get the result of the calculation as a sampling of the circuit. On the background of this process we have “State Vector” as the state of the qubits and “Unitary Matrix” as the operation of the quantum circuit itself.

How to convert unitary matrix to X gates?

Algorithm is proposed to convert arbitrary unitary matrix to a sequence of X gates and fully controlled Ry, Rz and R1 gates. This algorithm is used to generate Q# implementation for arbitrary unitary matrix.

How to check the unitary matrix in Qiskit?

As a small problems we can check the process by checking the unitary matrix. Now we see the process using Qiskit which is a famous quantum computing tools on python. We can get only the final result of the circuit as, Now we want to see the operation inside. Getting the unitary matrix This is the unitary matrix of the quantum circuit.

How are quantum gates described in a matrix?

Algorithms for a quantum computer are usually described as a sequence of quantum gates (such as Pauli X, Hadamard or CNOT) acting on register of qubits, followed by a sequence of measurements. Any quantum gate can be described as a unitary matrix acting on a vector representing the current state of a quantum computer.

How are the gates in a quantum circuit ordered?

Quantum gates are ordered in chronological order with the left-most gate as the gate first applied to the qubits. In other words, if you picture the wires as holding the quantum state, the wires bring the quantum state through each of the gates in the diagram from left to right. That is to say is the unitary matrix CBA C B A .

How to create an application on a quantum computer?

To create an application on a quantum computer, we have to create a quantum circuit which is a combination of quantum gates. We usually start all the qubits from 0 value and applying these quantum gates we finally get the result of the calculation as a sampling of the circuit.

Which is an example of a quantum circuit?

The above example circuit is depicted as acting on two qubits (or equivalently two registers consisting of one qubit). Gates acting on one or more qubit registers are denoted as a box. For example, the symbol is a Hadamard operation acting on a single-qubit register.
