Yesterday I used the first time a Quantum Computer myself.
Fascinating to work with qubits.
Easy part: python coding with qiskit on an #IBM Quantum instance in Washington is very straight forward and easy to understand (I am quite experienced with cloud computing). I have 10 minutes compute time for free.
Hard part: understanding the mathematical quantum stuff in detail. It is fun to play with algorithms and to execute stuff. But I am not able to understand really the math.
