We propose a scheme for nonadiabatic noncyclic geometric quantum computation in a
decoherence-free subspace (DFS). The physical system we used is a cavity quantum …

Abstract Deutsch–Jozsa (DJ) algorithm, as the first example of quantum algorithm, performs
better than any classical algorithm for distinguishing balance and constant functions. Here, a …

Nonadiabatic geometric quantum computation protected by dynamical decoupling combines
the robustness of nonadiabatic geometric gates and the decoherence-resilience feature of …

The effect of noise on the transmission of quantum state has attached much interest recently.
Here we investigate the effect of different types of quantum noise on deterministic exact …

Multiple‐qubit logic gates, as an essential part of quantum logic gates, have wide practical
application in quantum computation. Here, a scheme to directly construct a multiple‐qubit …

Quantum state transfer (QST) and entangled state generation (ESG) are important building
blocks for modern quantum information processing. To achieve these tasks, convention …

Due to a strong zero-phonon-line emission, narrow inhomogeneous broadening, and stable
optical transition frequencies, the quantum system consisting of negatively charged silicon …

Single-and two-qubit nonadiabatic noncyclic geometric quantum computation (NNGQC)
have been put forward in theory (Liu B.-J. et al., Phys. Rev. Res. 2 (2020) 043130). The …

Unconventional nonadiabatic geometric quantum computation not only possesses the
geometric robustness of conventional ones but also avoids the need to remove the …
