Open Quantum

Visual Studio

Write, validate, and run OpenQASM in Visual Studio

Browse live backends, run OpenQASM circuits on real QPUs and simulators, and follow jobs and results without leaving your editor. Syntax highlighting works before you even sign in, and new accounts start with $50 in free credits.

The Open Quantum panel in Visual Studio Code, showing a Bell-state circuit and its measurement counts

Run a circuit and see its status and measurement counts without leaving the editor.

OpenQASM 2 and 3, built in

Syntax highlighting and inline error checking for .qasm, .qasm2, .qasm3, and .openqasm files, with problems flagged as you type. Works out of the box, no account needed.

Explore every backend

Browse backends with live status, queue depth, and Spark availability, including your private devices. Open any one to see its coupling map and native gates, then select it to start a job.

Validate, quote, and run

Set a backend and configuration, then validate to get a credit quote before anything is spent. Pick a plan and a queue, and submit to real QPUs and simulators.

Jobs and results in the editor

Track your job history as it refreshes in place. Open any job for its status and credits, with measurement counts as a chart or table and downloads as JSON or a notebook.

Up and running in three steps

STEP 1

Install the extension

Install the Open Quantum extension from the Visual Studio Marketplace. Highlighting and error checking work immediately, before you ever sign in.

STEP 2

Set your SDK key

Create a key at openquantum.com/settings/keys and set it from the Open Quantum view. New accounts include $50 of free Spark credits.

STEP 3

Run a circuit

Open a .qasm file, pick a backend, review the quote, and submit. The job opens in the Jobs explorer with status, credits, and a counts chart.
