In-place implementation of Quantum-Gimli
We present an in-place implementation of the Gimli permutation, a NIST round 2 candidate for lightweight cryptography and provide an upper bound for the required quantum resource in depth and gate-counts. In particular, we do not use any ancilla bits and the state that our circuit produces is not entangled with any input, which offers further freedom in the usability and allows for a widespread use in different applications in a plug-and-play manner.
