Q-Kit or Quantum-Kit is a graphical quantum circuit simulator. Q-Kit enables building and designing quantum circuits, visualizing the effect of quantum gate operations as probability distributions of quantum states or on a Bloch Sphere. It is suitable for both educational and research purposes and is available for free!

We are at a remarkable moment in science and engineering, where Quantum networks may be the building block for secure communications and could eventually form a globe-spanning quantum Internet.

Canadian startup D-Wave Systems Inc. is offering a real-time online quantum computing environment called Leap. Leap is the latest addition to the quantum cloud?services that virtualize quantum computing for almost anyone with a computer and a broadband connection to use. D-Wave's latest 2,048-qubit processor has to be kept close to absolute zero to function, and Leap allows anyone to sign up to a D-Wave 2000Q quantum annealer. D-Wave is offering an open-source software development kit (SDK) called Ocean.

Use QISKit to create quantum computing programs, compile them, and execute them on one of several backends (online Real quantum processors, and simulators). Documentation & Tutorials

Several experiments performed on IBM's Quantum Experience demonstrating envariance ? entanglement assisted invariance. Envariance is a recently discovered symmetry of composite quantum systems, which is at the foundational origin of physics and a quantum phenomenon of pure states. These very easily reproducible and freely accessible experiments on Quantum Experience provide simple tools to study the properties of envariance.

Beyond classical computing (quantum computational supremacy)

Aim: Perform a quantum computation that cannot be performed classically in any reasonable amount of time.

Key issues:

-Are quantum computers more powerful than classical computers?

-For which computations do the classical and quantum runtimes diverge?

-Can we achieve quantum computational supremacy without fault tolerance?
