Complete characterization of the directly implementable quantum gates used in the IBM quantum processors [PDF]
Phys. Lett. A 384 (2020) 126387, 2018 Quantum process tomography of each directly implementable quantum gate used in the IBM quantum processors is performed to compute gate error in order to check viability of complex quantum operations in the superconductivity-based quantum computers introduced by IBM and to compare the quality of these gates with the corresponding gates implemented using

High-fidelity Rydberg quantum gate via a two-atom dark state [PDF]
, 2017 A modified Rydberg blockade gate that employs adiabatic following of a two-atom dark state is proposed. The scheme is resilient to the uncertainty in the interaction strength and can be employed to achieve fault-tolerant quantum computation with neutral ...

Optimized Unconventional Geometric Gates in Superconducting Circuits
Applied Sciences, 2023 Nonadiabatic Abelian geometric quantum computation has been extensively studied, due to its fast manipulation and inherent noise resistance. However, to obtain the pure geometric phase, the quantum state is required to evolve along some special paths to ...

Long-range quantum gate via Rydberg states of atoms in a thermal microwave cavity [PDF]
, 2015 We propose an implementation of a universal quantum gate between pairs of spatially separated atoms in a microwave cavity at finite temperature. The gate results from reversible laser excitation of Rydberg states of atoms interacting with each other via ...

Non-adiabatic charge state transitions in singlet–triplet qubits
New Journal of Physics, 2013 In double quantum dot singlet–triplet qubits, the exchange interaction is used in both quantum gate operation and the measurement of the state of the qubit. The exchange can be controlled electronically by applying gate voltage pulses.
