Semi-definite program for smooth min-entropy

You do not need a double objective function to solve this. Given $\rho_{AB}$ let $\rho_{ABC}$ be any purification of $\rho_{AB}$. Then we can write the smooth min-entropy as the following SDP \begin{...

Access IBM Q processors from MatLab

As far as I know, there is no MatLab library for the IBM quantum experience. It may be possible to call Qiskit from Matlab

Can my MatLab code be used as a good simulator of a quantum computer?

After using the simulator, I am very impressed! From what I can tell, it has everything necessary to be universal. I will likely be using this quite a bit. To test drive it, I implemented a simple ...

Is there a way to map the Cu3 gate to represent a unitary matrix whose elements are complex in nature

You can essentially just read off those angles. Consider the top-left matrix element $$ U_{00}=-0.2840-0.5319i=e^{i\gamma}\cos(\theta/2). $$ If you take the mod-square, you get $$ |U_{00}|^2=0.2840^2+...

Quantum Image Processing Application

I think a good place to start is the chapter on quantum image processing in Qiskit Texbook. It introduces possible representations as well as some working code. A popular format for quantum storage of ...
