Qibo: a framework for quantum simulation with hardware acceleration

Abstract

We present Qibo, a new open-source software for fast evaluation of quantum circuits and adiabatic evolution which takes full advantage of hardware accelerators. The growing interest in quantum computing and the recent developments of quantum hardware devices motivates the development of new advanced computational tools focused on performance and usage simplicity. In this work we introduce a new quantum simulation framework that enables developers to delegate all complicated aspects of hardware or platform implementation to the library so they can focus on the problem and quantum algorithms at hand. This software is designed from scratch with simulation performance, code simplicity and user friendly interface as target goals. It takes advantage of hardware acceleration such as multi-threading CPU, single GPU and multi-GPU devices.

The Path to Proton Structure at One-Percent Accuracy

“…For instance, the block "Neural Net" implements by default the neural network which after hyperoptimization has the architecture displayed in Fig. 3.9, but it could be replaced by any other parametrization, even by a quantum circuit [187] based on the QIBO library [188]. Similarly, the χ 2 with t 0 uncertainties could be replaced by any other cost function.…”

Quantum simulation with just-in-time compilation

“…In our case, if a particular operator is not defined in the cuQuantum library, the compatibility with Cupy allows us to fall back to the custom operators of the Cupy backend to maintain good performances without complicating the code. For a full list of primitives and models for quantum computing simulation available in Qibo 0.1.7 please refer to [10] and Sec. 3 in [12].…”

“…2.5 Ref. [10]. The multi-gpu scheme can be used with multiple physical GPU devices, if available, but also with a single GPU that is re-used for multiple state slices during the calculation.…”

“…In this context, we have developed the Qibo [10][11][12] framework, an open-source, full stack API written in Python, which supports circuit-based quantum simulation, adiabatic evolution simulation and quantum hardware control [13]. The Qibo structure since release 0.1.7 is shown in Fig.…”

Algebraic Bethe Circuits

“…We performed numerical simulations to verify and illustrate our theoretical results, using the open-source library Qibo [47,48]. We numerically solved the Bethe equations ( 2) and simulated the unitary circuits for two excited states of the XXX and XXZ (∆ = 0.5) models for N = 24 qubits and M = 2, 3 magnons respectively, and for the ground state of the XXZ model (∆ = 0.5), for N = 24 qubits.…”
