Abstract

We introduce the Piquasso quantum programming framework, a full-stack open-source software platform for the simulation and programming of photonic quantum computers. Piquasso can be programmed via a high-level Python programming interface enabling users to perform efficient quantum computing with discrete and continuous variables. Via optional high-performance C++ backends, Piquasso provides state-of-the-art performance in the simulation of photonic quantum computers. The Piquasso framework is supported by an intuitive web-based graphical user interface where the users can design quantum circuits, run computations, and visualize the results.

Popular summary

Photonic quantum computing has attracted growing interest due to experimental demonstrations of quantum advantage and promising routes toward fault-tolerant architectures. Photons offer several advantages, including room-temperature operation, mature optical technologies, and naturally robust entanglement. Nonetheless, photonic quantum computers still face significant limitations, underscoring the importance of efficient classical simulators. These simulators are crucial for benchmarking noisy hardware, designing circuits, exploring heuristic algorithms using quantum neural networks, and assessing algorithmic resilience to noise.

To aid photonic quantum computing research, we introduce Piquasso (PhotonIc QUAntum computer Simulator SOftware), a simulator for both discrete and continuous-variable photonic quantum computing. Piquasso provides a high-performance, flexible, and extensible platform for simulating, analyzing, and differentiating photonic quantum circuits. It supports quantum advantage schemes such as (Gaussian) Boson Sampling and enables photonic quantum machine learning through integration with TensorFlow or JAX.
