Accelerating the commercialization of quantum computing involves making Rigetti QPUs available to AWS customers. Through the partnership with AWS, end users may create quantum algorithms with our cutting-edge quantum hardware, opening up a plethora of applications and research opportunities that will drive the sector forward.
Rigetti Superconducting Quantum Processors
The global, gate-model Rigetti quantum processors are built on tunable superconducting qubits. Applications for universal, gate-based quantum computers can be found in machine learning, combinatorial optimization, and chemical modelling. Coherent superconducting qubits may effectively imitate and comprehend the behavior of biochemical processes, such as protein folding and photosynthesis, because they function according to the same quantum mechanical rules that control nature.
Furthermore, in order to identify more optimal solutions among an infinite number of options, such as in global logistics management, quantum computers can traverse exponentially more state space.
The architecture of the Rigetti Ankaa-series processors is scalable to high qubit counts and is based on tileable tunable-coupler technology. These chips have quick gate speeds and program execution rates thanks to their parametric-resonance and fast DC pulse-based logic gates. Rigetti’s QPU page provides performance metrics for existing Rigetti systems, such as coherence times and gate fidelities.
There are three main subsystems in rigetti processors. First, a compiler tool chain optimises user programs into machine-native instructions. These instructions are then sequenced as calibrated electrical impulses by a low-latency hardware controller. Ultimately, these electrical signals are logically transduced as digital quantum gates and measurement instructions by the qubits, which are composed of coherent superconducting circuit elements.
About Rigetti’s Quantum Chips
The improved readout capabilities of Rigetti’s Ankaa processor help to improve overall circuit fidelities. Fast gate speeds for many entangling gate families and a speedup in quantum processing times are additional system enhancements and device features.

With its square topology, four-fold connection, and two ISWAP entangling gates, the Ankaa chip design enables developers to minimise circuit depth and optimise programs for performance. SWAP gates connect non-nearest neighbour qubits by transferring quantum information throughout the Ankaa processor. The underlying compiler is extensively optimised for the “layout problem” because these can be expensive procedures.
FM control is used to activate Rigetti’s two-qubit entangling gate mechanism, usually known as ISWAP. One qubit’s frequency is flipped into resonance with a nearest-neighbor qubit on Ankaa devices for a predetermined amount of time. While all qubits on Ankaa systems may be manipulated in the same manner, this technique necessitates that at least half of the qubits on the Ankaa graph be controllable.
The goal of the quantum integrated circuit is to reduce inter-qubit cross-talk. Decoherence’s impact on an algorithm can be estimated by multiplying the algorithm’s circuit depth by the gate duration (~40 [1Q]-70 ns [2Q]) and comparing the qubit lifetimes (~20 μs).
Conclusion
Users can access their quantum hardware by using the superconducting quantum processors that Rigetti supplies to AWS. The tileable architecture of these CPUs allows for faster gate timings and scalability. Applications in a variety of industries include machine learning, optimisation, and simulation. The goal of Rigetti and AWS’s partnership is to hasten the commercialization of quantum computing technologies.
