Top 7 C++ Quantum Projects

qpp

2 505 7.9 C++

Modern C++ quantum computing library
blackbird

1 69 0.0 C++

Blackbird is a quantum assembly language for continuous-variable quantum computation, that can be used to program Xanadu's quantum photonics hardware and Strawberry Fields simulator. (by XanaduAI)
WorkOS

sponsored

The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
HartreeFock

15 49 7.1 C++

A program implementing the Hartree–Fock (also post-HF: MP2, CCSD(T), CIS and TDHF/RPA)/self-consistent field method (also DIIS) with Gaussian orbitals

Project mention: Help making plot for experiment | /r/cpp_questions | 2023-06-02

For this one I used my own code that draws the chart: https://github.com/aromanro/HartreeFock
QCSim

15 24 9.3 C++

Quantum computing simulator

Project mention: Which is the best programming language for Quantum Computing? | /r/QuantumComputing | 2023-07-11

I implemented one myself, just for fun: https://github.com/aromanro/QCSim I intend to extend/improve it further. For somebody that knows C++ maybe it's worth checking out.
DFTAtom

3 22 4.7 C++

Density Functional Theory in real space, for atoms, LDA and LSDA (by aromanro)
DFTQuantumDot

3 22 5.4 C++

Density Functional Theory with plane waves basis, applied on a 'quantum dot'. Volumetric visualization of orbitals with VTK

Project mention: Help making plot for experiment | /r/cpp_questions | 2023-06-02

In this one I used VTK to plot 3D data: https://github.com/aromanro/DFTQuantumDot
VQMCMolecule

2 13 5.6 C++

Variational Quantum Monte Carlo for a molecule, using Fokker-Planck/Langevin approach
InfluxDB
