Abstract

We theoretically propose an alternative method to realize a deterministic SWAP gate using shortcuts to adiabatic passage based on the approach of Lewis-Riesenfeld invariants in cavity quantum electronic dynamics (QED). By combining Lewis-Riesenfeld invariants with quantum Zeno dynamics, the SWAP gate can be achieved deterministically. The numerical results show that our scheme presents a fast and robust approach to achieve SWAP gates.

Fast and noise-resistant implementation of quantum phase gates and creation of quantum entangled states

Ye‐Hong Chen, Yan Xia, Qing-Qin Chen +1 more

The ``Lewis-Riesenfeld phases'' which play a crucial role in constructing shortcuts to adiabaticity may be a resource for the implementation of quantum phase gates. By combining ``Lewis-Riesenfeld invariants'' with ``quantum Zeno dynamics,'' we propose an effective scheme of rapidly implementing $\ensuremath{\pi}$ phase gates via constructing shortcuts to adiabatic passage in a two-distant-atom-cavity system. The influence of various decoherence processes such as spontaneous emission and photon loss on the fidelity is discussed. It is noted that this scheme is insensitive to both error sources. Additionally, a creation of $N$-atom cluster states is put forward as a typical example of the applications of the fast and noise-resistant phase gates. The study results show that the shortcuts idea is not only applicable in other logic gates with different systems, but also propagable for many quantum information tasks.

Generation of 3D entanglement between two spatially separated atoms via shortcuts to adiabatic passage

Lin Jing-bo, Yan Liang, Chong Song +2 more

We propose a scheme for generating 3D entanglement between two atoms trapped in two spatially separated cavities, respectively, via shortcuts to adiabatic passage based on the approach of Lewis–Riesenfeld invariants in cavity quantum electronic dynamics. By combining Lewis–Riesenfeld invariants with quantum Zeno dynamics, we can generate 3D entanglement of the two atoms with high fidelity. The numerical simulation results show that the scheme is robust against the decoherence caused by the photon leakage and atomic spontaneous emission.

Shortcuts to adiabatic passage for multiqubit controlled-phase gate

Yan Liang, Qi‐Cheng Wu, Shi‐Lei Su +2 more

We propose an alternative scheme of shortcuts to a quantum controlled phase gate in a much shorter time based on the approach of Lewis-Riesenfeld invariants in cavity quantum electrodynamics systems. This scheme can be used to perform a one-qubit phase gate, a two-qubit controlled phase gate, as well as a multiqubit controlled phase gate. The strict numerical simulations demonstrate that the total operation time for implementing controlled phase gates is much shorter than previous schemes and very robust against decoherence.

Shortcuts to adiabatic passage for multiparticles in distant cavities: applications to fast and noise-resistant quantum population transfer, entangled states’ preparation and transition

Ye‐Hong Chen, Yan Xia, Qing-Qin Chen +1 more

In this paper, we study the fast and noise-resistant population transfer, quantum entangled states preparation, and quantum entangled states' transition by constructing the shortcuts to adiabatic passage (STAP) for multiparticle based on the approach of "Lewis-Riesenfeld invariants" in distant cavity quantum electronic dynamics (QED) system. Numerical simulation demonstrates that all of the schemes are fast and robust against the decoherence caused by atomic spontaneous emission and photon leakage. Moreover, not only the total operation time but also the robustness in each scheme against decoherence is irrelevant to the number of qubits. This might lead to a useful step toward realizing the fast and noise-resistant quantum information processing in current technology.

One-step implementation of a deterministic SWAP gate via a shortcut to adiabatic passage

Chun‐Ling Zhang, Mei Lu, Cheng-Li Luo +1 more

Abstract The quantum logic gate is a basic operation in quantum computing. SWAP gates are quite useful as a type of two-qubit logic gate. In this paper, we propose a fast scheme to get a deterministic SWAP gate between two atoms in just one step. In this scheme the experimental parameters, such as evolution time, laser parameters and so on, do not need to be controlled precisely. This greatly simplifies the actual operation. Meanwhile, the strict numerical simulations show that decoherence arising from spontaneous emission and cavity decay may be allowed to some extent. What is more, the idea can be used to generate a SWAP gate between two spatially separate atoms. It is worth noting that our scheme simplifies the complex steps found in some pre-existing schemes.

Fast generations of tree-type three-dimensional entanglement via Lewis-Riesenfeld invariants and transitionless quantum driving

Jin‐Lei Wu, Xin Ji, Shou Zhang

Recently, a novel three-dimensional entangled state called tree-type entanglement, which is likely to have applications for improving quantum communication security, was prepared via adiabatic passage by Song et al. Here we propose two schemes for fast generating tree-type three-dimensional entanglement among three spatially separated atoms via shortcuts to adiabatic passage. With the help of quantum Zeno dynamics, two kinds of different but equivalent methods, Lewis-Riesenfeld invariants and transitionless quantum driving, are applied to construct shortcuts to adiabatic passage. The comparisons between the two methods are discussed. The strict numerical simulations show that the tree-type three-dimensional entangled states can be fast prepared with quite high fidelities and the two schemes are both robust against the variations in the parameters, atomic spontaneous emissions and the cavity-fiber photon leakages.
