Ratings and reviews

Good for a quick visualisation of a single qubit on the Bloch sphere. My two issues with this app are: 1) I find the Bloch sphere projection a bit "squished", it doesn't look like a sphere 2) The maths typesetting is a bit dodgy. Missing brackets around the coefficients of the basis states in the state |psi>. Putting the kets |0> and |1> in the vector is unusual and not well defined. Kets should be typeset with proper angle brackets, not less-than and greater-than symbols. It would be nice to be able to switch decimal point conventions.

Hi. There are 2 major misconceptions in your app: 1. phi should start from the X axis, not Y. 2. phi should rotate counter-clockwise, not clockwise (remember Euler identity circle). It would be nice if you'll add some opacity/material to the sphere, as well as let the user rotate it. Also add gates and reset. Cheers and thanks for the effort.

its a great help... thank you so so much
