Crate roqoqo_qryd

roqoqo-qryd

The roqoqo-qryd rust crate implements qoqo support for quantum computers and quantum computer emulators of the QRydDemo project.

The QRydDemo project builds on Quantum computers using Rydberg atoms. qoqo is quantum computing toolkit by HQS Quantum Simulations.

The roqoqo-qryd package contains the following functionality:

Interface to the current QRydDemo WebAPI

At the moment QRydDemo WebAPI allows access to Quantum Hardware Emulators of different device topology. roqoqo-qryd supports interfacing with the corresponding REST-API with low level calls as well as a high-level backend to qoqo quantum programs. For this it provides the backend APIBackend to evaluate roqoqo quantum programs and the api_devices module to represent devices available on the emulators.

QRydDemo specific hardware operations (prototype)

Rydberg atom based quantum devices support, in principle, operations not commonly found in other quantum hardware. Changes in device topology are one of these operations. roqoqo-qryd adds support for changes in device topology to roqoqo via the operations in its pragma_operations module. Note that this is a preview prototype and does not represent a finalized set of operations on the QRydDemo hardware.

Local simulator supporting specific hardware operations

roqoqo-qryd includes a local QuEST based simulator for quantum devices supporting the Rydberg specific quantum operations. The simulator is intended to let users test the capabilities of quantum hardware with the additional operations. roqoqo-qryd provides the simulator via the SimulatorBackend backend the implements the roqoqo Backend trait.The backend uses the device prototypes in roqoqo-qryd’s qryd_devices module. Note that the devices for the simulator do not represent a finalised design for QRydDemo.
