# Controlled phase gate qiskit

A two-qubit control-**phase** **gate**. Left: sequence of pulses on the control and target qubits to demonstrate a control-**phase** **gate**. The dashed line indicates the π pulse used to set the control qubit to state 1. Right: in-**phase** and quadrature signals of the echo observed on the target qubit measured by heterodyne detection.

This makes global **phases** consequential (controlling turns the global **phase** into a relative, observable **phase**). It turns out the new definition of U in OpenQASM 3 is the same as the definition in **Qiskit**. If you are writing circuits in OpenQASM 3 or **Qiskit**, then global **phases** matter. Therefore you should use this new definition. In IBM **Quantum** Composer, the **phase** disk at the terminus of each qubit gives the local state of each qubit at the end of the computation. Hovering over a **phase** disk gives full details. For example: **Quantum** Composer has a series of **quantum phase**-shift gates that allow us to shift this **phase** by the following: T. **gate**.

Abstract and Figures. Quantum computing has been the buzzword in 2020 (apart from COVID-19). The global awakening is noticeable, with an active community of thousands working rigorously on honing.

A **gate** object can create a **gate** to which a control qubit is added by calling a control() method. The argument of control() is an integer, which can be used to represent the number of control qubits. When the programmer calls the control() method, a function called add_control() is executed, creating a **gate** for the ControlledGate class.

Two-qubit gates such as **controlled** gates are slightly different from ordinary 1-qubit gates; they let you create interaction between your qubits. In general, this translates into using 1 qubit as the control qubit, and the other as the acted-on qubit. Mathematically, this is not super complex, but intuitively you might have to think once or twice about what is going on.
