The Company’s 84-qubit Ankaa™-2 system is now publicly available to all of its customers via Rigetti Quantum Cloud Services (QCS™). The Ankaa-2 system has achieved a 98% median 2-qubit fidelity, a 2.5x performance improvement compared to the Company’s previous QPUs.

(Nasdaq: RGTI) (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, announced today that its 84-qubit Ankaa™-2 quantum system was made publicly available to all of its customers via Rigetti’s Quantum Cloud Services (QCS™) on December 20, 2023. The Ankaa-2 system is based on Rigetti’s fourth generation chip architecture that features tunable couplers and a square lattice, enabling high fidelity 2-qubit operations compared to the Company’s previous systems.

（纳斯达克：RGTI）（“Rigetti”或“公司”）是全堆栈量子经典计算的先驱，今天宣布其84量子比特Ankaa™-2量子系统通过Rigetti的量子云服务（QCS）向其所有客户公开™) 2023年12月20日。Ankaa-2系统基于Rigetti的第四代芯片架构，该架构具有可调耦合器和方形晶格，与该公司以前的系统相比，可以实现高保真2量子比特操作。

Ankaa-2 is also the Company’s highest qubit count quantum processing unit (QPU) available to the public. Following the internal deployment of Ankaa-1, the Company made iterative improvements through internal R&D to support enhancements to Ankaa-2. As a result, Ankaa-2 achieved a 2% median 2-qubit gate error rate — less than half the error rate of the Company’s previous systems.

Ankaa-2也是该公司向公众提供的量子比特数最高的量子处理单元（QPU）。在内部部署Ankaa-1之后，该公司通过内部研发进行了迭代改进，以支持对Ankaa-2的增强。因此，Ankaa-2实现了2%的中位数2比特门错误率-不到该公司以前系统错误率的一半。

These fidelity improvements can be attributed to a variety of technology updates to the Ankaa-2 system: Implementation of a new chip fabrication process, leading to qubits with fewer atomic defects that would otherwise reduce quantum coherence timesIncorporation of new superconducting PCB technology that improves thermal performanceElectronics improvements that generate control signals with less noise “Rigetti’s focus on improving our median 2-qubit fidelities is a crucial part of our mission to build the world’s most powerful computers.

这些保真度的提高可归因于Ankaa-2系统的各种技术更新：实施了新的芯片制造工艺，产生原子缺陷较少的量子比特，否则会减少量子相干时间新的超导PCB技术的引入，提高了热性能电子技术的改进，产生了噪音较小的控制信号“Rigetti专注于提高我们的中位数2量子比特保真度，这是我们建造世界上最强大的计算机的使命的关键部分。
