qiskit
Qiskit is an open-source SDK for working with quantum computers at the level of extended quantum circuits, operators, and primitives.
In this series, we'll be introduced to the theories of QC from notations, measurements, superposition, and entanglement to sophisticated algorithms such as Grover's and Shor's. We will use worked mathematical examples accompanied (mostly) by code verification (using Qiskit and/or Cirq). Most of the problems will be taken from [@Rieffel2011], and their mathematical solutions will be more thoroughly explained for clarity. This is to really understand the concepts. I suggest you check out [@Rieffel2011,@Bernhardt2019] for deeper or more theoretically approachable knowledge.
