An improved architecture of a realizable quantum computer for quantum programming languages

Quantum SoC and On-Chip Circuit Synthesis in the NISQ Era

“…However, quantum computation is more like a declarative paradigm, which means a quantum computational algorithm always performs an integrated transformation with all intrinsic variables and obtains the fnal output (i.e., all fnal states of variables inside an entire unitary matrix). A detailed discussion of the different paradigms is given in [10]. Te design of a declarative computational model and declarative architecture is more simplifed than that of an imperative architecture.…”

“…From the universal viewpoint of a quantum computer, the essential organization of a hybrid quantum computer can be generalized as "quantum data with classic control." Tis architectural model mainly contains a classic controller (or classic computing part), a quantum memory unit, a quantum computing unit, and a quantum input-output (I/ O) device [10]. If a quantum computing device is designed for a specifc use, e.g., quantum communication or quantum random number generation (QRNG), the organization and architecture can be simplifed.…”

“…We have designed several mechanisms, like the decoherence-free subspace and hierarchy QECC, to suppress decoherence in the quantum computing process and qubit states. In the NISQ era, these mechanisms can also be considered in the design of QSoC, see Figure 2 and details in [8,10]. Now, we give a detailed description and a comparative study of the "storage-centric" and the "computing-centric" paradigms.…”
