The ParityQC Architecture, the generalized version of the LHZ architecture, provides a fundamentally new way to solve real-world problems on quantum computers, defining both the hardware layout and the algorithms. It is a quantum computing architecture that represents a new pathway to work efficiently with every currently available quantum computing platform, from NISQ towards fully error-corrected devices in the future.
The conventional approach to quantum computing, and in particular quantum optimization, typically requires the implementation of a large number of interactions between different qubits. Such an implementation quickly becomes unfeasible in practice, especially since the structure of these interactions can change from problem to problem. To solve these issues, the ParityQC Architecture establishes an additional level of encoding between the problem and the hardware. With this novel quantum computing architecture, only globally uniform interactions between neighbouring qubits are required. All problem-depending interactions are reduced to local operations which are much easier to control.
