X gate qiskit

Is there any way that I can self define a control gate in qiskit?

In this article, we are going to see how to apply NOT gate on a given input 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. QISKIT is the package that sits between quantum algorithms from one side, and the physical quantum device from the other side. It translates the common programming languages like Python into quantum machine language.

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:. The number of desired quantum and classical wires may also be expressed by supplying instances of QuantumRegister and ClassicalRegister as arguments to QuantumCircuit. The QuantumCircuit class contains a large number of methods and attributes. The purpose of many of its methods is to apply quantum operations to a quantum circuit. Most of its other methods and attributes either manipulate or report information about a quantum circuit.

This is often supplied as an integer:.

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:. This will entangle the two qubits such that the combined state becomes:.

Since the output will be deterministic,. 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. Please note that these methods are available after obtaining an AerSimulator backend. Change Language. Nonsensical circuit with multiqubit gate examples. Applies the phase gate to quantum wire 1, subject to the state of the control qubit on wire 0. Example parameterized circuit. Explore offer now. Note that the arguments to the Parameter constructors in this code snippet are strings, in this case ones that contain theta characters. SX qc. Current difficulty :.

Trending in News. Applies the SX square root of X gate to quantum wire 1, subject to the state of the control qubit on wire 0. Instructions and Gates In Qiskit, all operations that may be applied to a quantum circuit are derived from the Instruction class. Last Updated : 14 Sep, Quantum Teleportation in Python. Applies two CNOT gates whose control qubits are on wires 2 and 3. Commonly used methods in the Instruction class Names Example Notes copy inst. It is sometimes useful to create a quantum circuit in which values may be supplied at runtime. Using the append method The append method appends an instruction or gate to the end of the circuit on specified wires, modifying the circuit in place. Note that the variable cr refers to an instance of ClassicalRegister. 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:. Saves the simulator state as a unitary matrix of the run circuit. Controlled-unitary operations are derived from the ControlledGate class, which is a subclass of Gate.
