Quantum circuits for isometries [PDF]
Physical Review A, 2016 We consider the decomposition of arbitrary isometries into a sequence of single-qubit and Controlled-NOT (C-NOT) gates. In many experimental architectures, the C-NOT gate is relatively 'expensive' and hence we aim to keep the number of these as low as possible.

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

Natural parametrized quantum circuit
Physical Review A, 2022 Noisy intermediate scale quantum computers are useful for various tasks such as state preparation and variational quantum algorithms. However, the non-Euclidean quantum geometry of parameterized quantum circuits is detrimental for these applications.

Efficient universal quantum circuits [PDF]
Quantum Information and Computation, 2009 Universal circuits can be viewed as general-purpose simulators for central classes of circuits and can be used to capture the computational power of the circuit class being simulated. We define and construct quantum universal circuits which are efficient and has very little overhead in simulation.

Architecture aware compilation of quantum circuits via lazy synthesis [PDF]
Quantum, 2022 Qubit routing is a key problem for quantum circuit compilation. It consists in rewriting a quantum circuit by adding the least possible number of instructions to make the circuit compliant with some architecture's connectivity constraints.
