Amazon Braket provides cloud access to multiple quantum processors through a managed service. The platform connects users to hardware from several different providers and includes simulation tools for algorithm testing.

Braket supports processors from Rigetti, Oxford Quantum Circuits, QuEra, IonQ, D-Wave, and Xanadu. Each provider contributes distinct hardware characteristics that influence how algorithms run and which problem types suit each system best.

The service offers four simulator options through AWS. SV1 handles state vector simulations, TN1 manages tensor network workloads, DM1 focuses on density matrix calculations, and a local simulator runs free on user machines for initial testing.

Pricing follows a pay-as-you-go model based on task execution and shot counts. Users pay separately for simulator time, quantum device access, and data storage costs associated with their experiments.

AWS introduced Braket Direct in 2023 to provide dedicated device access for high-priority projects. This capability helps researchers secure consistent time on specific quantum processors without competing for shared resources.

Developers can run quantum algorithms across multiple hardware types without managing separate accounts or toolchains. The unified environment reduces setup complexity when comparing results from different quantum systems.

3. IonQ

IonQ develops trapped-ion quantum computers with cloud-accessible qubit counts. The company runs its systems through Amazon Braket with reservation-based access for its 30-qubit Forte processor. Investors track these figures because larger qubit counts and gate fidelity directly affect algorithm performance.

Current disclosures list the Forte system at 30 qubits with gate fidelity figures reported in technical updates. These metrics determine how well the hardware can maintain superposition and entanglement during computation. Market data shows IonQ trading as a pure-play quantum stock with a $13.3 billion capitalization as of July 2025.

Trapped-ion designs offer different trade-offs than superconducting approaches. IonQ's platform supports quantum gate operations that users access through cloud reservations. Performance scales with qubit quality rather than raw quantity alone.

4. Rigetti Computing

Rigetti Computing fabricates superconducting quantum processors and offers cloud access. The company supplies systems to major platforms and focuses on hardware scale.

Their current processors reach the 84-qubit level with the Ankaa-2 system. Superconducting circuits support fast gate operations and remain central to their roadmap.

Rigetti combines classical and quantum resources in hybrid workflows. Users run parts of algorithms on conventional servers while offloading quantum subroutines through cloud APIs.

The revenue model centers on cloud access fees and hardware sales. Integration with Amazon Braket expands reach without requiring customers to maintain their own cryogenic infrastructure.

Market observers note Rigetti among pure-play quantum stocks alongside peers like IonQ and D-Wave. The company holds a multi-billion market capitalization and continues to refine error rates on its chips.

D-Wave Quantum sells annealing systems for optimization workloads. The company operates quantum annealers through Amazon Braket and trades as QBTS. Market capitalization stands at $6.5 billion with year-to-date performance of negative 36.1 percent.

Annealing architecture suits problems that need to find the lowest energy state among many possible configurations. This approach differs from gate-based systems that use quantum gates to manipulate qubits. Research suggests annealing performs well when solutions involve searching through large sets of discrete options.

Available system sizes vary by model generation. Earlier systems offered fewer than 2000 qubits while newer versions exceed 5000 qubits. Experts recommend matching qubit count to the size of optimization problems under consideration.

Typical use cases include scheduling, logistics routing, and portfolio optimization. Companies test these applications to see whether quantum annealing reduces computation time compared with classical methods. Results remain problem-dependent and require careful benchmarking.

Investors track D-Wave Quantum as one of several pure-play stocks in the quantum computing sector. The company focuses on annealing rather than gate-based approaches used by other firms. Performance metrics such as market capitalization and stock returns provide context for sector comparisons.
