September 2020 product updates

• 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 IBM Quantum™ Composer circuit, indicates the probability that the qubit is in the|0> 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 system

The highest Quantum Volume (QV) recorded for each system is now listed on the Quantum services(opens in a new tab) page.
