This work experimentally realizes a universal nonadiabatic geometric quantum gate set in a superconducting qubit chain and demonstrates the noise-resilient feature of the realized single-qubit geometric gates by comparing their performance with the conventional dynamical gates with different types of errors in the control field.

Quantum state conversion in opto-electro-mechanical systems via shortcut to adiabaticity
Adiabatic process has found many important applications in modern physics, the distinct merit of which is that it does not need accurate control over the timing of the process. However, it is a slowExpand
Perfect quantum state transfer in a superconducting qubit chain with parametrically tunable couplings.
Faithfully transferring the quantum state is essential for quantum information processing. Here we demonstrate a fast (in 84 ns) and high-fidelity (99.2%) transfer of arbitrary quantum states in aExpand
Plug-and-Play Approach to Nonadiabatic Geometric Quantum Gates.
It is shown that nonadiabatic geometric gates can be constructed in an extensible way, called NHQC+, for maintaining both flexibility and robustness against certain types of noises. Expand
High fidelity quantum state transfer in electromechanical systems with intermediate coupling
It is found that both the small () and large () coupling regimes of this hybrid system can not support high fidelity quantum state transfer before significant technique advances, but in the intermediate coupling regime (J ~ g1 ~ g2), high fidelity Quantum information transfer can be implemented, providing a promising route towards high fidelityquantum state transfer in similar coupled resonators systems.

Nonadiabatic Geometric Quantum Computation with Parametrically Tunable Coupling
The nonadiabatic geometric quantum computation is promising as it is robust against certain types of local noises. However, its experimental implementation is challenging due to the need of complexExpand
Circuit quantum electrodynamics simulator of flat band physics in a Lieb lattice
The concept of flat band plays an important role in strongly correlated many-body physics. However, the demonstration of the flat band physics is highly nontrivial due to intrinsic limitations inExpand
Controllable high-fidelity quantum state transfer and entanglement generation in circuit QED
The result shows that the proposed scheme is very robust against both the cavity decay and qubit relaxation, the fidelities of the state transfer and entanglement preparation process could be very high and it is shown to be insensitive to the inhomogeneous of qubit-resonator coupling strengths.

Experimental observation of simultaneous wave and particle behavior in a narrowband single-photon wave packet
Light's wave-particle duality is at the heart of quantum mechanics and can be well illustrated by Wheeler's delayed-choice experiment. The choice of inserting or removing the second classicalExpand
