X gate qiskit

In this article, we are going to see how to apply NOT gate on a given x gate qiskit 0 or 1 using quantum gates, we have to convert 0 to 1 and 1 to 0. This can be done easily in classical computers, but how can we do this in quantum computers. We have to represent the input in qubits and then we apply the X representation of NOT gate in the quantum computer operation in that qubit after that return the resultant qubit, x gate qiskit.

In Qiskit, quantum programs are normally expressed with quantum circuits that contain quantum operations. Quantum circuits are represented by the QuantumCircuit class, and quantum operations are represented by subclasses of the class Instruction. A quantum circuit may be created by supplying an argument that indicates the number of desired quantum wires qubits for that circuit. This is often supplied as an integer:. Optionally, the number of desired classical wires bits may also be specified. The first argument refers to the number of quantum wires, and the second argument the number of classical wires:.

Is there any way that I can self define a control gate in qiskit? I have define a new quantum gate qg , and it will be applied to the "data" qubit if the "control" qubit is 1, and it will not be applied if the "control" qubit is 0. How can I implement this? I don't know if you may have already solved this problem already but I think the closest tool Qiskit provides to do what you are asking is the ControlledGate Class. Taking the specifications and prior code you gave this was the closest working example I could come up with:. I notice you have two qubits in your data register, so just to be thorough I've provided an example below with a two qubit controlled, two target qubit gate based:. The code examples above all came from here: qiskit. Hi Randomizer , I don't know if you may have already solved this problem already but I think the closest tool Qiskit provides to do what you are asking is the ControlledGate Class. Taking the specifications and prior code you gave this was the closest working example I could come up with: from qiskit. I notice you have two qubits in your data register, so just to be thorough I've provided an example below with a two qubit controlled, two target qubit gate based: from qiskit. Hope that helps!

The barrier method takes as an optional argument the qubit wires on which to place a barrier. Note that a circuit passed into the compose method is allowed to have fewer quantum or classical wires than the original circuit. This article is being improved by another user right now, x gate qiskit.

Interested in learning how to program quantum computers? Bell states are the four states that can be created when two qubits are maximally entangled. The four states are represented as so:. Now we will go through each state and see how to implement it using quantum circuits. The first Bell state is incredibly easy to implement as it can be created using a two qubit circuit consisting of a Hadamard gate and CNOT gate found below:.

How can I implement this? Using the compose method The compose method returns a new circuit composed of the original and another circuit. Applies rotation with 3 Euler angles to qubit 1. Applies the X gate to quantum wire 3, subject to the state of the control qubits on wires 0, 1, and 2. I, Identity qc. Figure The following code snippet uses the decompose method.
