Quantum circuit unoptimization
Physical Review ResearchOptimization of circuits is an essential task for both quantum and classical computers to improve their efficiency. In contrast, classical logic optimization is known to be difficult, and a lot of heuristic approaches have been developed so far.

Quantum-circuit black hole lasers. [PDF]
Sci Rep, 2021 AbstractA black hole laser in analogues of gravity amplifies Hawking radiation, which is unlikely to be measured in real black holes, and makes it observable. There have been proposals to realize such black hole lasers in various systems. However, no progress has been made in electric circuits for a long time, despite their many advantages such as high-

Quantum circuit optimization using quantum Karnaugh map. [PDF]
Sci Rep, 2020 AbstractEvery quantum algorithm is represented by set of quantum circuits. Any optimization scheme for a quantum algorithm and quantum computation is very important especially in the arena of quantum computation with limited number of qubit resources. Major obstacle to this goal is the large number of elemental quantum gates to build even small quantum

Circuit quantum electrodynamics [PDF]
Reviews of Modern Physics, 2021 Quantum mechanical effects at the macroscopic level were first explored in Josephson junction-based superconducting circuits in the 1980's. In the last twenty years, the emergence of quantum information science has intensified research toward using these circuits as qubits in quantum information processors.

Initial-State Dependent Optimization of Controlled Gate Operations with Quantum Computer [PDF]
Quantum, 2022 There is no unique way to encode a quantum algorithm into a quantum circuit. With limited qubit counts, connectivity, and coherence times, a quantum circuit optimization is essential to make the best use of near-term quantum devices.

Triunitary quantum circuits [PDF]
Physical Review Research, 2021 We introduce a novel class of quantum circuits that are unitary along three distinct "arrows of time". These dynamics share some of the analytical tractability of "dual-unitary" circuits, while exhibiting distinctive and richer phenomenology. We find that two-point correlations in these dynamics are strictly confined to three directions in $(1+1 ...
