Quantum Buffer Design Using Petri Nets
This paper introduces a simplified quantum Petri net (QPN) model and uses
this model to generalize classical SISO, SIMO, MISO, MIMO and priority buffers
to their quantum counterparts. It provides a primitive storage element, namely
a quantum S-R flip-flop design using quantum CNOT and SWAP gates that can be
replicated to obtain a quantum register for any given number of qubits. The
aforementioned quantum buffers are then obtained using the simplified QPN model
and quantum registers. $\!\!$The quantum S-R flip-flop and quantum buffer
designs have been tested using OpenQASM and Qiskit on IBM quantum computers and
simulators and the results validate the presented quantum S-R flip-flop and
buffer designs.
