Although Zapata Computing has been supporting Rigetti’s processors for a long time, this new development will represent a tighter integration that will provide additional improvements. Many of the quantum programs being run today are hybrid classical/quantum programs that require usage of both types of resources to arrive at a result. Because of this, the efficiency of the interface between the classical and quantum resources becomes very important and can have a big impact on the overall runtime for a particular program. The new development will integrate Orquestra, Zapata’s unified platform for building and deploying quantum applications, directly with Rigetti’s Quantum Cloud Services (QCS). In order to run a particular hybrid program, the classical and quantum processor may need to exchange data thousands of times and this integration will improve the speed of those exchanges and reduce overall latency for the end users. In addition, this improvement in latency may have an interesting side effect in improving solution quality because the qubit calibrations in a quantum processor tend to drift over time which can start causing more errors. By shortening the runtime of a program, the amount of drift is also minimized. Integrating the software will also provide other advantages by enabling the optimization and automation of the compiler toolchain for error mitigation purposes. This integrated compiler toolchain functionality is expected to be available to customers in Q2 2022.
