Qiskit SDK v2.0 Released: A New Era For Quantum Developers

IBM will discuss Qiskit SDK v2.0's intriguing new features below. Qiskit SDK v2.0 may be more concerned with removing the old than introducing the new

This significant release begins with the introduction of a C-language API for interacting with the SparseObservable class

[{"selector":"#anim-e6ed0a2c-806d-44ec-bd81-e6495506f951","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-a3e70eda-72e2-4903-8644-4ef34cb1fbd2 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-12.514648210040342%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}]

To allow us to keep enhancing the SDK, additional deprecation warnings were added to many of the minor releases in the prior v1.x series

[{"selector":"#anim-719325a2-49b2-463c-9700-724c94ee190b","keyframes":{"transform":["rotate(-540deg) scale(0.1)","none"],"opacity":[0,1]},"delay":0,"duration":1000,"fill":"both","iterations":1}] [{"selector":"#anim-b9ea4ac8-e474-45b6-be38-3746834d22f2 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(12.514648210040342%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}]

Porting more Qiskit SDK functionality to Rust has resulted in a 2x speedup for circuit construction benchmarking and a 20% speedup for translation benchmarking

[{"selector":"#anim-c4e210ad-5fd0-4a84-8e39-fb11fdaa2751","keyframes":{"transform":["scale(1)","scale(1.5)","scale(0.95)","scale(1)"],"offset":[0,0.33,0.66,1]},"delay":0,"duration":1450,"easing":"ease-in-out","fill":"both","iterations":1}] [{"selector":"#anim-e0069b55-db3c-4e81-9f10-6f35f4b9587c [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-12.514648210040342%, 0, 0) translate(-25%, 0%) scale(1.5)","translate3d(0%, 0, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

In order to prepare for future modifications to dynamic circuits on IBM QPUs, Qiskit SDK v2.0 offers useful additional options for structuring your circuits

[{"selector":"#anim-3acd7e05-8335-4f76-954f-282e6c356500","keyframes":{"transform":["translate3d(-116.00001%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(.2, 0, .8, 1)","fill":"both"}] [{"selector":"#anim-395dac61-dee9-4a36-91cf-169053951ddb","keyframes":{"transform":["rotateZ(-180deg)","rotateZ(0deg)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(.2, 0, .5, 1)","fill":"forwards"}] [{"selector":"#anim-06f96bdf-d3d3-4660-a964-71c290075dc5 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-12.514648210040342%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}]

All of the deprecations IBM has mentioned since the introduction of Qiskit SDK v1.0 have been eliminated in Qiskit SDK v2.0 due to the fact that this is a significant release

[{"selector":"#anim-3ad7752d-5da2-4ca0-bb01-677c1f9e4488","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-c76e4f8d-4aab-4eb9-b720-e03d48fe27c8","keyframes":{"transform":["translate3d(0px, -217.99337%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-8c20c588-ac1d-4f74-a66d-7986e3fc116c [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-12.514648210040342%, 0, 0) translate(-25%, 0%) scale(1.5)","translate3d(0%, 0, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

Although Qiskit Pulse offers useful features for hardware manipulation and pulse-level access to qubit data, these features are not free

[{"selector":"#anim-61c6d695-7bfd-44ff-a3cf-904d5b7d9b90 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-0bdb8a3b-4b2b-42b9-9837-cea508f70330","keyframes":{"transform":["translate3d(-115.09434%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-57ddb016-c6f0-49dd-bcf7-a4663ca639e6","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-12d060c2-2e9d-413e-a513-840894ed1854","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]
