AQT builds compact, rack-mountable trapped-ion quantum computers based on research from the University of Innsbruck, one of the world's leading trapped-ion research groups. AQT's systems are designed to fit into standard server racks, making them practical for integration into existing IT infrastructure. The company provides cloud access to its systems and has deployed quantum computers at several European research institutions. AQT focuses on accessibility and industrial applicability.

Amazon Braket is AWS's fully managed quantum computing service, providing access to quantum hardware from multiple vendors including IonQ, Rigetti, OQC, and QuEra through a unified cloud interface. It offers an SDK for building and testing quantum algorithms, high-performance simulators (SV1, TN1, DM1), and hybrid quantum-classical job capabilities that integrate with broader AWS services like Lambda, S3, and CloudFormation. Braket serves as a hardware-agnostic entry point for enterprises exploring quantum.

Azure Quantum is Microsoft's cloud quantum computing platform, integrating hardware from partners including IonQ, Quantinuum, Pasqal, and Rigetti. Beyond cloud brokerage, Microsoft is developing its own topological qubit technology — a fundamentally different approach that aims to create inherently error-protected qubits. The Q# programming language and Quantum Development Kit (QDK) provide enterprise-grade tooling. Microsoft also collaborated with Quantinuum to demonstrate 12 logical qubits and a hybrid chemistry simulation in 2024.

Google Cloud provides marketplace access to quantum computing hardware and services, including Google's own quantum processors and third-party systems like Alice & Bob's Boson 4. It bridges Google Quantum AI's research hardware with enterprise cloud infrastructure, enabling developers to experiment with quantum algorithms through familiar Google Cloud tooling.
