%description
A quantum computer simulator framework with up to 24 qubits. It allows to
define general single qubit gates and general controlled single qubit
gates. For convenience, it currently provides the most common gates (X, Y,
Z, H, Z, S, T, Rx, Ry, Rz, CNOT, SWAP, Toffoli or CCNOT, Fredkin or
CSWAP). 'qsimulatR' also implements noise models. 'qsimulatR' supports
plotting of circuits and is able to export circuits to 'Qiskit'
<https://qiskit.org/>, a python package which can be used to run on IBM's
hardware <https://quantum-computing.ibm.com/>.
