Develops Triple Alpha, a development environment for writing, compiling, optimizing, and deploying quantum programs across processors and simulators. Its software-first model is paired with a Singapore hardware testbed for hardware-software integration.
Triple Alpha is a development environment for building quantum programs at multiple abstraction levels. It supports compilation, optimization, deployment, and access across quantum processors and simulators, with the aim of keeping applications portable across hardware platforms. The system spans different computing abstractions.
Operations are based in Singapore, with an office in Dublin. A Singapore hardware testbed, established after assembling and integrating a quantum computer, is used to tighten hardware-software integration. The platform depends on maintaining effective integrations as hardware platforms, standards, and customer requirements evolve; hardware providers may favor proprietary software stacks.
