0262024-04-16Deprecation of the legacy backend.run() interfaceHello IBM Quantum Network,

We have deprecated the legacy backend.run() interface in Qiskit Runtime. The backend.run() interface originally coexisted with the original (V1) primitives model as the dedicated “direct hardware access” entry point. With the introduction of the V2 primitives interface, the new SamplerV2 class now fulfills that role.

Support for backend.run() will officially be dropped on or around 15 October 2024. Please refer to this migration guide for instructions on how to migrate any existing code that uses backend.run() to the new V2 primitives interface.

0232024-03-22Focus on utility-scale computing: Retirement of cloud simulators and IBM Quantum LabCloud simulators


In line with our focus on utility-scale quantum computing, we’re retiring our cloud simulators on 15 May 2024. We invite you to start using the Qiskit Runtime local testing mode (with qiskit-ibm-runtime 0.22.0 or later), which makes it possible to perform development and testing locally prior to submitting your workloads to our >100-qubit systems.


This change emphasizes a shift toward quantum hardware capabilities, since the benefits of quantum hardware have surpassed the utility of simulators in helping determine which applications have the greatest potential for advantage.

Guide: Migrate from cloud simulators to local simulators.

Noisy simulation with Qiskit Aer primitives.

Getting started with Qiskit Aer.

Leverage IBM Watson Studio as an alternative to your local environment.
IBM Quantum Lab

We are also retiring IBM Quantum Lab on 15 May 2024 to increase our focus on utility-era tooling.

You can execute jobs locally with Qiskit, or you can set up your own cloud-based environment.

Starting today, you can download your Lab files in bulk from the Lab platform. Bulk file downloads will remain available until 15 November 2024.
0222024-03-06Qiskit SDK 1.0 is here!Qiskit SDK 1.0 is our way of marking the start of a new era for programming quantum computers — one that is centered on performance, stability, and usability. But what does this mean exactly? We’ve made a variety of changes over the past few releases to prepare for this, including:

A more performant SDK: We’ve spent years working to improve Qiskit’s overall performance, and this release represents the accumulation of many different improvements over the past 18 months. Qiskit 1.0 will enable users to easily build and transpile circuits with 100+ qubits, and lays the groundwork for future 1,000+ qubit workloads.

A stable API: With the launch of Qiskit 1.0, we are beginning a new, more stable release cycle and updating our versioning support. Get ready for significantly fewer breaking changes and much more robust backwards-compatibility and bug support than users have ever had before!

A leaner set of libraries: We’ve consolidated and focused the core features of Qiskit by removing the metapackage architecture and splitting out several modules into separate packages. This allows us to focus much more on stability and maintainability while enabling the wider open source community to contribute interesting new features. You’ll find more details on why and how we made this decision in our migration guide.

An SDK built for an open-source ecosystem: The transpiler plugin interface and the broader Qiskit Ecosystem program are designed to encourage scientists, engineers and software developers to try their hand at building new extensions of Qiskit’s core capabilities, so we can all work together to advance the field of quantum computing.

Many more features and improvements have come with the release of Qiskit 1.0, such as a redesign of the Sampler and Estimator primitives, native OpenQASM 3 support, and hefty memory and performance improvements. We highly recommend reading through the Qiskit 1.0 Release Summary to learn about all of the exciting changes that Qiskit 1.0 brings.
0212024-03-05Updates to IBM Quantum Platform Administration AnalyticsAt IBM, we strive to provide industry-leading experiences in quantum computing. Today, we are enriching the Administration Analytics Dashboard on IBM Quantum Platform with new visual features, to help Hub Administrators monitor their organization’s reserved capacity and usage with ease.

Visible for only Hub and Group Administrators, upgrades to the Administration views include:

Total contracted reserve capacity displayed in minutes. Premium Plan contracts express reserved capacity in units of Queue Slots (or system share), which corresponds to a number of usable minutes that varies over time. Now, the analytics dashboard represents your Queue Slots with a fixed conversion rate of 1600 minutes per Queue Slot over a 28-day rolling window. This conversion reflects our working target for IBM Quantum systems’ availability to process user workloads. Representing Queue Slots as a more stable reference helps your administrators to better monitor and manage reserved capacity and usage. Please note, this does not change the contract definition of Queue Slots, nor your contracted reserved capacity.

Enriched usage plots through the overlay of contracted reserved capacity and usage. This new visual aid enables enhanced usage monitoring across your Hub and Groups.

New visual aids to identify Groups and Projects that have reached a state of over-usage. This will aid administrators to take action to either modify their capacity allotment or to request lowering their system usage.

Updated Group, and Project capacity management to show minutes in addition to shares. This permits administrators to more clearly and quantifiably determine the desired partition of the available reserved capacity. At this time, Groups continue to uniquely inherit the assigned reserved capacity, while Projects partake in the reserved capacity inherited by their respective Group according to the Project’s relative priority and usage.

We hope you will enjoy these improvements, and we look forward to see how Administrators will use the new insights that these updates unlock.

0192024-02-23Changes how start times happen in Qiskit RuntimeOnce these systems are retired, they will no longer accept or process jobs. We suggest retrieving any job data from important past jobs before the systems are retired. Please refer to the following documentation for more information on retrieving past jobs.
0182024-02-14Changes to Qiskit Runtime PrimitivesLast year we introduced Qiskit Patterns as the four-step archetype for how to use quantum systems. In step 2, circuits and observables are prepared to efficiently run on quantum hardware. This step ensures that users don’t incur unnecessary costs when making Primitive (Sampler or Estimator) queries, because (potentially unbounded-cost) classical computations are done on the client side. To further encourage this mode of operation, beginning 1 March 2024, Qiskit Runtime will require that circuits and observables are transformed to use only instructions supported by the system (referred to as instruction set architecture (ISA) circuits and observables) before being submitted to the primitives. This change also streamlines service operations to produce faster results and make more efficient use of our fleet of quantum systems. See the transpilation documentation for instructions to transform circuits and the primitive examples to see this coupled with operator transformations. Due to this change, the primitives will no longer perform layout or routing operations; consequently, transpilation options referring to those tasks will no longer have any effect. Users can still request that the Primitives skip optimization of input circuits via options.transpilation.skip_transpilation.
0172024-02-02Retiring ibm_kolkata & ibm_mumbaiRetiring ibm_kolkata and ibm_mumbai on or around 4/1/2024. We suggest retrieving any past jobs before the systems are retired.
0162023-12-01New 133 qubit backend addedWe are pleased to announce that we have released our first IBM Quantum system based on a Heron quantum processor, the 133-qubit ibm_torino. Leveraging signal delivery innovations from Osprey, Heron delivers the performance of an Egret at the scale of an Eagle. Specifically, using the tunable coupler architecture first demonstrated on ibm_prague, ibm_torino achieves our best score yet on the new layer fidelity benchmark, an EPLG of 0.8% across a 100-qubit chain. At the level of individual two-qubit gates, the median error of 0.35% eclipses the previous best on a 100Q+ system by nearly a factor of two, while shrinking the median gate time to a mere 124 ns, roughly a factor of four faster than on a typical Eagle. Note that in contrast to the directional ECR and CX gates used on Eagle and older systems, the native two-qubit gate here is a controlled-Z (CZ) rotation, which is inherently symmetric between the two qubits, simplifying the task of mapping circuits onto physical qubits. Heron will also serve as the foundation on which we’ll follow our updated development roadmap. The first introduction of IBM Quantum System Two will feature a collection of three Heron quantum processors. We’re referring to Heron as the most performant quantum processor in the world and it will be the technological path forward as we further drive our roadmap through this Era of Utility towards quantum computing at scale.
