November 30, 2018


The objectives of this competition are to build interest in Xanadu's open source software and libraries, including

  1. Strawberry Fields, a Python library for designing, simulating, and optimizing photonic quantum circuits, its corresponding ecosystem, and advancing the field of continuous-variable quantum computation, and
  2. PennyLane, a cross-platform Python library for quantum machine learning, automatic differentiation, and optimization of hybrid quantum-classical computations.
In addition, by expanding the Xanadu software user-base, we aim to bring together a community focused on quantum computation, quantum optics, and quantum machine learning, and maintain the status of the Strawberry Fields and PennyLane documentation as a leading resource hub for photonic quantum computing education and research.
