The most recent updates and features in IBM Quantum Experience
New public API page: Use this page to learn how to use the public REST APIs by reviewing the spec, exploring each API in detail, and working through an example.
See each qubit’s state, at a glance. The phase disk visualization, at
the end of each qubit in your circuit, indicates the probability that the qubit is in the state, the phase of the state vector in the complex plane, and the reduced purity of the qubit state.
See the Quantum Volume of each backend: In the Your backends panel on the dashboard, the highest Quantum Volume (QV) recorded for each backend is now listed next to each backend’s name.
Circuit Composer has a new look!
Workspace customization. Now you can see more information in a shared context. Use the View menu to choose which tools you see, then drag to resize, or click the menu in each window to further customize it. You can also choose a light or dark workspace theme.
Get to work faster. Navigating to Circuit Composer in the menu now takes you directly to your workspace. Click the file icon next to the Circuit name to see all of your previously saved circuits.
New operations added. A new color scheme groups operations by type. For details about the available gates and operations, see the Operations glossary.
Note that the X gate is now represented by the symbol to match the other classical gates.
View Python code. Switch between editable OpenQASM and read-only Python code in the Code panel. Click the Open in Quantum Lab button to open the code in a Jupyter Notebook environment.
New q-sphere visualization. Unlike its cousin the Bloch sphere, the q-sphere uses nodes of varying sizes and colors arranged on a sphere to represent the state of a system of qubits. Click and drag the q-sphere to move it around! You can also view up to three visualizations at once. Note: we have removed the density matrix visualization.
PDF download. In addition to PNG and SVG, you can now download images of visualizations and circuits as PDFs.
No more built-in tabs. We have removed tabs from the interface. When you open a circuit from your list of circuit files, it will open in a new tab in your browser.
Easily run and monitor jobs. If you are signed in, you can click the Run Settings button to view and change Run settings, then use the Jobs panel to view your jobs, all without leaving the page. You can also see the qubit count of the backend, and a status tag if the backend is offline, not available, or in maintenance mode.
Qiskit Notebooks has a new name! Find Qiskit in the cloud under Quantum Lab.
