Proposal for implementing universal superadiabatic geometric quantum gates in nitrogen-vacancy centers
We propose a feasible scheme to implement a universal set of quantum gates based on geometric phases and superadiabatic quantum control. Consolidating the advantages of both strategies, the proposed… Expand

By modifying the shapes of the Raman pulses, this work theoretically proposes and experimentally demonstrates a shortcut-to-adiabatic protocol that is robust against control parameter variations and provides an efficient and practical way to control quantum systems. Expand
Experimental observation of double coherent stimulated Raman adiabatic passages in three-level Λ systems in a cold atomic ensemble
Coherent stimulated Raman adiabatic passages (STIRAP) based on a dark state have many applications in diverse quantum systems. In the case of large single-photon detuning in three-level… Expand
Nonadiabatic holonomic quantum computation in decoherence-free subspaces with trapped ions
Implementing non-adiabatic holonomic quantum computation in decoherence-free subspaces may consolidate the advantages of both strategies and thus leads to suppression of both local and collective… Expand
Geometric Rydberg quantum gate with shortcuts to adiabaticity.
We propose a controlled-PHASE gate for neutral atoms in which one of the qubit state components adiabatically evolves along the multiple-atom eigenstate formed by the chirped laser pulse coupling to… Expand

Geometric Quantum Computation with Shortcuts to Adiabaticity
Accelerating geometric quantum gates through non-cyclic evolution and shortcut to adiabaticity
Fast and robust quantum gates is the cornerstone of fault-tolerance quantum computation. In this paper, we propose to achieve quantum gates based on non-cyclic geometric evolution. Dynamical phase… Expand
Detecting topological exceptional points in a parity-time symmetric system with cold atoms.
A scheme to detect the topological exceptional points in a two-level parity-time symmetric system embedded in a larger Hilbert space constructed by a four-level cold atomic system and may pave a promising way to explore the novel properties of non-Hermitian systems. Expand
