The Prevalence of Straight Shots in Control Space for Reaching Optimal Quantum Performance
Yiyou Chen, Gabriele Herr, Herschel Rabitz
Gradient-based algorithms are often applied to identify an optimal control for maximizing a quantum objective functional by following a steepest ascent path to the top of the contr…
Linear-depth quantum circuits for loading Fourier approximations of arbitrary functions
Mudassir Moosa, Thomas W. Watts, Yiyou Chen +2
The ability to efficiently load functions on quantum computers with high fidelity is essential for many quantum algorithms. We introduce the Fourier Series Loader (FSL) method for…
Quantum Approximation of Normalized Schatten Norms and Applications to Learning
Yiyou Chen, Hideyuki Miyahara, Louis-S. Bouchard +1
Efficient measures to determine similarity of quantum states, such as the fidelity metric, have been widely studied. In this paper, we address the problem of defining a similarity…
Decoherence Mitigation by Embedding a Logical Qubit in a Qudit
Hideyuki Miyahara, Yiyou Chen, Vwani Roychowdhury +1
Quantum information stored in a qubit is rapidly lost to the environment. The realization of robust qubits is one of the most important challenges in quantum computing. Herein we p…
