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.

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.

Simultaneous estimation of multiple eigenvalues with short-depth quantum circuit on early fault-tolerant quantum computers [PDF]
Quantum, 2023 We introduce a multi-modal, multi-level quantum complex exponential least squares (MM-QCELS) method to simultaneously estimate multiple eigenvalues of a quantum Hamiltonian on early fault-tolerant quantum computers.

Quantum circuits for quantum channels [PDF]
Physical Review A, 2017 We study the implementation of quantum channels with quantum computers while minimizing the experimental cost, measured in terms of the number of Controlled-NOT (C-NOT) gates required (single-qubit gates are free). We consider three different models. In the first, the Quantum Circuit Model (QCM), we consider sequences of single-qubit and C-NOT gates ...

Pauli Error Propagation-Based Gate Rescheduling for Quantum Circuit Error Mitigation
IEEE Transactions on Quantum Engineering, 2022 Noisy intermediate-scale quantum algorithms, which run on noisy quantum computers, should be carefully designed to boost the output state fidelity. While several compilation approaches have been proposed to minimize circuit errors, they often omit the ...

A Parallel Quantum Circuit Implementations of LSH Hash Function for Use with Grover’s Algorithm
Applied Sciences, 2022 Grover’s search algorithm accelerates the key search on the symmetric key cipher and the pre-image attack on the hash function. To conduct Grover’s search algorithm, the target cipher algorithm should be efficiently implemented in a quantum circuit ...

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.
