In Aug 2024, IBM's quantum-safe cryptographic algorithms were officially published as part of the first post-quantum cryptography standards by NIST. Among the three new standards, IBM's ML-KEM (CRYSTALS-Kyber) and ML-DSA (CRYSTALS-Dilithium) were developed in collaboration with industry partners, while SLH-DSA (SPHINCS+) was co-developed by a researcher now at IBM. These standards are crucial for securing data against future quantum computer threats. IBM continues to lead in post-quantum cryptography, integrating these advancements into its products and services to ensure a quantum-safe future.

In April 2021, AWS partnered with the Hebrew University of Jerusalem on a new quantum computing project as part of the company's ongoing research into this field, which began in 2019. These include the Amazon Quantum Solutions Lab, which supports businesses in exploring quantum applications, the AWS Center for Quantum Computing, a research and development organization, and Amazon Braket, a cloud-based quantum computing tool developed to speed up research and discovery.

IBM (US)

IBM has adopted a strategy of building an open quantum ecosystem through its IBM Quantum Network, emphasizing accessibility via the cloud. Its core competencies lie in superconducting qubit technology, quantum hardware scalability, and hybrid quantum-classical computing. IBM's major activities include partnerships with enterprises, governments, and academic institutions to co-develop quantum applications and continuous roadmap releases. The company demonstrates vertical integration, combining hardware, middleware, and cloud services to maintain control over the full technology stack. Furthermore, IBM has set clear milestones through its quantum technology roadmap, targeting error-corrected systems and quantum advantage in the coming years. Its focus on advancing quantum-safe cryptography and developing real-world use cases across industries such as finance, healthcare, and materials science further strengthens its leadership. By combining research depth with commercialization efforts, IBM continues to position itself as one of the most influential players in the global quantum computing landscape.

AWS (US)

AWS (Amazon Web Services) pursues a strategy focused on democratizing access to quantum computing through its Amazon Braket platform, offering customers multiple hardware options in a single cloud service. Its core competencies are cloud infrastructure, scalable computing, and integrating quantum with classical workloads. AWS's major activities include collaborations with hardware providers (IonQ, Rigetti, QuEra, and Xanadu) rather than direct acquisitions, highlighting a partnership-driven approach. The company primarily follows a horizontal integration strategy, aggregating quantum hardware providers under one service umbrella without owning the core hardware. In addition, AWS invests in research through the AWS Center for Quantum Computing in collaboration with the California Institute of Technology, aimed at advancing error correction and fault-tolerant quantum systems. The company also promotes developer adoption by providing software development kits (SDKs) and simulation tools that allow researchers and enterprises to experiment and prototype hybrid quantum-classical algorithms. Through its vast global cloud infrastructure and pay-as-you-go model, AWS emphasizes accessibility, scalability, and cost efficiency, positioning itself as a key enabler for early adoption of quantum technologies across industries such as logistics, finance, and pharmaceuticals.
