A hardware-based emulation framework for quantum data centers is developed by splitting qubit coupling maps on one processor and using ancilla qubits to simulate transduction and fiber noise, with demonstrations on IBM hardware and ion-trap systems for algorithms like Grover's search and QFT.

abstract
Master equations in the Lindblad form describe evolution of open quantum systems that is completely positive and simultaneously has a semigroup property. We analyze a possibility to derive this type of master equations from an intrinsically discrete dynamics that is modelled as a sequence of collisions between a given quantum system (a qubit) with particles that form the environment. In order to illustrate our approach we analyze in detail how a process of an exponential decay and a process of decoherence can be derived from a collision-like model in which particular collisions are described by SWAP and controlled-NOT interactions, respectively.
