GSQAS: Graph Self-supervised Quantum Architecture Search [PDF]
, 2023 Quantum Architecture Search (QAS) is a promising approach to designing quantum circuits for variational quantum algorithms (VQAs). However, existing QAS algorithms require to evaluate a large number of quantum circuits during the search process, which makes them computationally demanding and limits their applications to large-scale quantum circuits ...

The quantum sine-Gordon model with quantum circuits
Nuclear Physics B, 2021 Analog quantum simulation has the potential to be an indispensable technique in the investigation of complex quantum systems. In this work, we numerically investigate a one-dimensional, faithful, analog, quantum electronic circuit simulator built out of Josephson junctions for one of the paradigmatic models of an integrable quantum field theory: the ...

Capacity and quantum geometry of parametrized quantum circuits [PDF]
PRX Quantum 2, 040309 (2021), 2021 To harness the potential of noisy intermediate-scale quantum devices, it is paramount to find the best type of circuits to run hybrid quantum-classical algorithms. Key candidates are parametrized quantum circuits that can be effectively implemented on current devices. Here, we evaluate the capacity and trainability of these circuits using the geometric

An Electromagnetic-Flux-Distribution Model for the Analyses of Superconducting Josephson Junction Circuits and Quantum Phase-Slip Junction Circuits [PDF]
IEEE Transactions on Applied Superconductivity, pp. 1-6, 2022, 2021 Josephson junctions and the quantum phase-slip (QPS) junctions are two quantum circuit elements introduced by superconducting electronics to create various hybrid circuits. Josephson junctions bring the developments of superconducting quantum interference devices (SQUIDs) and single-flux quantum (SFQ) digital circuits; as the dual element of Josephson ...

Optimal synthesis of multivalued quantum circuit [PDF]
Phys. Rev. A 92, 062317 (2015), 2015 Although many of works have been done in multivalued quantum logic synthesis, the question whether multivalued quantum circuits are more efficient than the conventional binary quantum circuits is still open. In this article we devote to the optimization of generic multivalued quantum circuits.
