AWS Lambda enables organizations to access many types of functions from AWS’ cloud-based services, such as: Data processing, to execute code based on triggers, system states, or user actions. You will likely need to write code to integrate systems and handle complex tasks or incoming network requests. How does AWS Lambda work?

The security attacks demonstrated so far, for example, show that it is possible to induce errors in qubits via crosstalk, fingerprint the quantum computer devices, or even leak information across reset gates. Given their promise, these computers are available, in some cases even freely, for access as cloud-based devices.
