Qbsolv,a decomposing solver, finds a minimum value of a large quadratic unconstrained binary optimization (QUBO) problem by splitting it into pieces solved either via a D-Wave system or a classical tabu solver. (Note that qbsolv by default uses its internal classical solver. Access to a D-Wave system must be arranged separately.)

QuCAT stands for Quantum Circuit Analyzer Tool. This open source python library provides standard analysis tools for superconducting electronic circuits, built around Josephson junctions. QuCAT features an intuitive graphical or programmatical interface to create circuits, the ability to compute their Hamiltonian, and a set of complimentary functionalities such as calculating dissipation rates or visualizing current flows in the circuit. QuCAT currently supports quantization in the basis of normal modes.

QuCoSi is a C++ library for simulating a quantum computer. The used qubits and gates are plain vectors and matrices that can be inspected and modified easily. Its emphasis lies on readability and ease of use.

NOTICE OF CONSOLIDATION & PARTNERSHIP PENDING As of April 2026, the 20 pipelines of the QCAUS/PDPBioGen suites are undergoing consolidation for high-scale institutional research. Core 'Ford 2026' algorithms remain the proprietary IP of the Ford Peace and Justice Foundation. Academic users at partner institutions are currently performing validation; all other commercial inquiries must contact the author QUANTUM SHIELD ORBITAL DEFENSE DETECTION SYSTEM 🚀 Overview Quantum Shield is a revolutionary defense system leveraging quantum sensing technologies for superior detection capabilities against stealth aircraft, drones, missiles, and submarines. By utilizing quantum entanglement, superposition, and other quantum phenomena, the system offers detection ranges and capabilities far beyond conventional radar systems.

"Relevant Data Storage System" (RDSS) eliminates the need of having the PC "end user" store their data by using a “forced remembrance” of the navigation address and or pathway of a folder hierarchy along with the assigned or designated file name for later data acquisition. The new innovative method I have created makes possible that any end user regardless of their native language can retrieve all relevant data no matter the language, be Chinese, English, Hindu, Italian, Russian, Hawaiian, even Klingon if wanted, etcetera. This means, the creator saves their data (in English as an example), but a Japanese "end user" can retrieve the SAME data without needing to know English at all. Of course, this process isn't meant to convert the English into the Japanese language. This method is meant only to insure anyone using any language known, can recover the SAME data without ever needing to know the original creator.

:awsum: You lost the game.

Simuquant is made to construct and simulate universal quantum circuits. It's GUI enables intuitive access and direct graphical feedback, making it useful in a classroom situation and the like. Simulation processing is done in parallel, utilizing parallel collections introduced in scala 2.9. This application has been created as part a bachelor-thesis at the Hamburg University of Applied Sciences. The thesis is available at: http://opus.haw-hamburg.de/volltexte/2012/1843/pdf/ba_dahl.pdf Future plans: - Operator grouping (enables repeated blocks) - Editable library

This repository is the home of the Superstaq development team's open-source work. Our quantum software platform is optimized across the quantum stack and enables users to write quantum programs in Cirq or Qiskit and target a variety of quantum computers and simulators.

An intermediate representation to construct and manipulate your quantum circuit and let you make own abstractions on the quantum circuit in native Julia. Yao supports both forward-mode (faithful gradient) and reverse-mode automatic differentiation with its builtin engine optimized specifically for quantum circuits. Top performance for quantum circuit simulations. Its CUDA backend and batched quantum register support can make typical quantum circuits even faster. Yao is designed to be extensible. Its hierarchical architecture allows you to extend the framework to support and share your new algorithm and hardware.

New project name is Atomlight. https://sourceforge.net/projects/atomlight

A "bitwise precision tool" bitrate calculator using MS-EXCELL programming. The results are used for DVD Video to audio-video streams. It helps compute VIDEO- & AUDIO-Bitrates, aspect ratio, screen size, choose audio format cbr. Has units MB,pixel,d:h:m:s, kbps, etc

Datagam is a tool for extracting data from output or punch files produced by GAMESS(US) or FireFly (old name PC GAMESS) packages. Mac GUI wrapper also available. Upstream version of the project goes to the launchpad. Only final versions of the source code and compiled binars will be available from this domain.

This is a set of octave-functions to simulate grover's quantum search algorithm in which we introduce spontaneously decaying qubits. See http://arxiv.org/abs/quant-ph/0609047. This is a modification to account for multiple item searching.

ossGathering collects information of the open source software. And shows the information that is collected in a variety of ways.

Package quantum-octave is a set of GNU Octave functions for simulating quantum computers.

staq is a modern C++ library for the synthesis, transformation, optimization and compilation of quantum circuits. staq is written in standard C++17 and has very low external dependencies. It is usable either through the provided binary tools, or as a header-only library that can be included to provide direct support for parsing & manipulating circuits written in the OpenQASM circuit description language. Inspired by Clang, staq is designed to manipulate OpenQASM syntax trees directly, rather than through an intermediate representation which makes retrieving the original source code impossible. In particular, OpenQASM circuits can be inspected and transformed (in most cases) without losing the original source structure. This makes staq ideally suited for source-to-source transformations, where only specific changes are desired. Likewise, this allows translations to other common circuit description languages and libraries to closely follow the OpenQASM source.
