Sizes

Control the size of a X gate using the data-size attribute. 

<x-gate data-size="xs"></x-gate>
<x-gate data-size="sm"></x-gate>
<x-gate data-size="base"></x-gate>
<x-gate data-size="lg"></x-gate>
<x-gate data-size="xl"></x-gate>

Disabled Gate

To display the disabled X gate, set the data-disabled attribute. 

<x-gate data-disabled></x-gate>

Connecting with Other Gates

To connect the X gate to the quantum gate of the lower bit, set the data-wire-top attribute. Similarly, set data-wire-bottom for the upper bits. 

<x-gate data-wire-top></x-gate>
<x-gate data-wire-bottom></x-gate>
<x-gate data-wire-top data-wire-bottom></x-gate>
<x-gate data-wire-top-disabled></x-gate>
<x-gate data-wire-bottom-disabled></x-gate>
<x-gate data-wire-top-disabled data-wire-bottom-disabled></x-gate>

To show disabled connections, use the data-wire-top-disabled and data-wire-bottom-disabled attributes. 

<x-gate data-wire-top-disabled></x-gate>
<x-gate data-wire-bottom-disabled></x-gate>
<x-gate data-wire-top-disabled data-wire-bottom-disabled></x-gate>
<x-gate data-wire-top-disabled data-disabled></x-gate>
<x-gate data-wire-bottom-disabled data-disabled></x-gate>
<x-gate data-wire-top-disabled data-wire-bottom-disabled data-disabled></x-gate>

IF directive

To apply a X gate conditionally, specify a data-if attribute; the condition (variable name) specified in the if directive can be set in the Measurement gate. 

<x-gate data-if="x"></x-gate>

If the gate is connected to another gates, the position of the if label will be adjusted automatically.

User Help Popup

As a user help, you can display the description and usage of the X gate as a popup. The popup will show on the mouse hover event. The content to be displayed can be specified in the <x-gate> tag as follows:

NOT Gate (Pauli X Gate)

Swaps the qubit pair of |0⟩ and |1⟩.

Drag and Drop

To make the X gate drag-and-droppable, specify the data-drag-and-drop attribute.
