Determination of Molecular Energies via Quantum Imaginary Time Evolution in a Superconducting Qubit System
Zhiwen Zong, Sainan Huai, Tianqi Cai +10
As a valid tool for solving ground state problems, imaginary time evolution (ITE) is widely used in physical and chemical simulations. Different ITE-based algorithms in their quant…
Shelf-stable quantum-dot light-emitting diodes with high operational performance
Desui Chen, Dong Chen, Xingliang Dai +8
Quantum-dot light-emitting diodes (QLEDs) promise high-performance and cost-effective electroluminescent devices. However, shelf stability of QLEDs, a must for practical applicatio…
Experimental realization of nonadiabatic geometric gates with a superconducting Xmon qubit
P. Z. Zhao, Zhangjingzi Dong, Zhenxing Zhang +3
Geometric phases are only dependent on evolution paths but independent of evolution details so that they own some intrinsic noise-resilience features. Based on different geometric…
Experimental realization of a fast controlled-Z gate via a shortcut-to-adiabaticity
Tenghui Wang, Zhenxing Zhang, Liang Xiang +8
For a frequency-tunable two-qubit system, a controlled-Z (CZ) gate can be realized by adiabatically driving the qubit system through an avoided level crossing between an auxiliary…
Single-shot realization of nonadiabatic holonomic gates with a superconducting Xmon qutrit
Zhenxing Zhang, P. Z. Zhao, Tenghui Wang +6
Nonadiabatic holonomic quantum computation has received increasing attention due to its robustness against control errors as well as high-speed realization. The original protocol o…
Experimental demonstration of work fluctuations along a shortcut to adiabaticity with a superconducting Xmon qubit
Zhenxing Zhang, Tenghui Wang, Liang Xiang +9
In a `shortcut-to-adiabaticity' (STA) protocol, the counter-diabatic Hamiltonian, which suppresses the non-adiabatic transition of a reference `adiabatic' trajectory, induces a qua…

Tenghui Wang, Zhenxing Zhang, Liang Xiang +10
Based on a `shortcut-to-adiabaticity' (STA) scheme, we theoretically design and experimentally realize a set of high-fidelity single-qubit quantum gates in a superconducting Xmon q…
Simulating a Topological Transition in a Superconducting Phase Qubit by Fast Adiabatic Trajectories
Tenghui Wang, Zhenxing Zhang, Liang Xiang +3
The significance of topological phases has been widely recognized in the community of condensed matter physics. The well controllable quantum systems provide an artificial platform…
Measuring the Berry Phase in a Superconducting Phase Qubit by a Shortcut to Adiabaticity
Zhenxing Zhang, Tenghui Wang, Liang Xiang +3
With a counter-diabatic field supplemented to the reference control field, the `shortcut to adiabaticiy' (STA) protocol is implemented in a superconducting phase qubit. The Berry p…
