Experimental Implementation of Universal Nonadiabatic Geometric Quantum Gates in a Superconducting Circuit.
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 processes have found many important applications in modern physics, the distinct merit of which is that accurate control over process timing is not required. However, such processes are…

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.
