〘 Quantum Information 〙

Language Requirement(s): None. Usage Requirements: Web-based; only internet connection and free sign-in (IBMid) required.

The IBM Quantum Platform offers some of the best resources for beginner and more advanced quantum computing I've ever seen. Accessable upon creation of an IBMid, this web-based resource allows users to send quantum programs straight to IBM's quantum processors. They also offer a variety of learning resources, including the Quantum Composer, a beautiful, clean interactive where individuals can toy around with quantum circuitry and immediately generate the corresponding code in Qiskit or OpenQASM 2.0. The platform offers courses in the fundementals of quantum computing (IBM Quantum Learning). If you're an individual interested in experimenting with quantum computing/programming, the IBM Quantum Platform is a must-have. The only drawback is the user is only allotted 10 minutes of runtime on IBM's GPU's per month, which depending on the complexity of your quantum algorithums, may be a lot or too little.

Language Requirement(s): Primary development in Q#, host scripts can be written in Python, C#, or F#. Also has support for Qiskit and OpenQASM. Usage Requirements: Integrates as an extension for VS Code or Jupyter Notebooks. Runs locally on standard desktop hardware, and connects online via Azure Quantum to execute jobs.

An open-source, domain-specific framework designed by Microsoft for building and executing quantum algorithms. The power from this framework stems from its high-level qubit resource management, and its local simulation and visualization abilities. Microsoft has been recently focusing on QDK for scientific applications, like (quantum) chemistry, so you can see the real-world usage of QDK first-hand. The link provided goes to Microsoft's QDK documentation, not the GitHub.

Language Requirement(s): Requires Python and Python packages (Numpy, Scipy, Cython, and Matplotlib). Works on any desktop/laptop OS.

QuTiP is an open-source software which simulates the dynamics of open quantum systems. It allows for numerical simulations of many Hamiltonians, even those with arbitrary time-dependence. These Hamiltonians have a large range of practical physics applications including quantum optics, trapped ions, quantum nanomechanical resonators, and superconducting surfaces. It being completely free makes it idea for exploring quantum mechanics/dynamics and having no licensing fees makes it a good pick for classrooms too.

Language Requirement(s): Built using Python, requires Python 3.

Cirq is yet another open-source framework for programming qunatum computers. Cirq is a Python library which allows for the writing, manipulation, optimization, and execution of quantum circuits and code on quantum computers and quantum simulators. One advantage of Cirq is its abstractions for dealing with modern noisy intermediate-scale quantum (NISQ) computers.

Language Requirement(s): C/C++. Usage Requirements: Requires a C/C++ compiler like Clang, GCC, etc., depending on the user's usage. Depending on what the user wants, you may need an MPI compiler and/or a GPU compiler.

QuEST stands for the Quantum Exact Simulation Toolkit. It is a high-performance simulator of quantum circuits, state-vectors, and density matrices too. QuEST also uses multithreading, GPU acceleration, and distribution to run ridiculously fast on laptops, desktops, and supercomputers. The developers pride themselves that "QuEST just works", meaning it is stand-alon, requires no installation, and is incredibly easy to compile and get running.
