Robust Control of Single-Qubit Gates at the Quantum Speed Limit
Xi Cao, Jiangyu Cui, Man Hong Yung +1
Fastness and robustness are both critical in the implementation of high-fidelity gates for quantum computation, but in practice, a trade-off has to be made between them. In this pa…
Iterative Gradient Ascent Pulse Engineering algorithm for quantum optimal control
Yuquan Chen, Yajie Hao, Ze Wu +6
Gradient ascent pulse engineering algorithm (GRAPE) is a typical method to solve quantum optimal control problems. However, it suffers from an exponential resource in computing the…
Experimental Realization of Two Qutrits Gate with Tunable Coupling in Superconducting Circuits
Kai Luo, Wenhui Huang, Ziyu Tao +12
Gate-based quantum computation has been extensively investigated using quantum circuits based on qubits. In many cases, such qubits are actually made out of multilevel systems but…
Global sensitivity analysis for optimization of the Trotter-Suzuki decomposition
Alexey N. Pyrkov, Yurii Zotov, Jiangyu Cui +1
The Trotter-Suzuki decomposition is one of the main approaches for realization of quantum simulations on digital quantum computers. Variance-based global sensitivity analysis (the…
Quantum Simulation of Resonant Transitions for Solving the Eigen-problem of an Effective Water Hamiltonian
Zhaokai Li, Xiaomei Liu, Hefeng Wang +5
It is difficult to calculate the energy levels and eigenstates of a large physical system on a classical computer because of the exponentially growing size of the Hilbert space. In…
Universal Quantum Control in Zero-field Nuclear Magnetic Resonance
Ji Bian, Min Jiang, Jiangyu Cui +7
This paper describes a general method for manipulation of nuclear spins in zero magnetic field. In the absence of magnetic fields, the spins lose the individual information on chem…
