Visual configuration segmentation of quantum states for phase identification in many-body systems
Yuan Yang, Zhengchuan Wang, Shi-Ju Ran +1
Artificial intelligence provides an unprecedented perspective for studying phases of matter in condensed-matter systems. Image segmentation is a basic technique of computer vision…
Visualizing Quantum Phases And Identifying Quantum Phase Transitions By Nonlinear Dimensionality Reduction
Yuan Yang, Zheng-Zhi Sun, Shi-Ju Ran +1
Identifying quantum phases and phase transitions is key to understand complex phenomena in statistical physics. In this work, we propose an unconventional strategy to access quantu…
High-Fidelity Entangling Gates for Quantum-Dot Hybrid Qubits Based on Exchange Interactions
Yuan-Chi Yang, S. N. Coppersmith, Mark Friesen
Quantum dot hybrid qubits exploit an extended charge-noise sweet spot that suppresses dephasing and has enabled the experimental achievement of high-fidelity single-qubit gates. Ho…
High-fidelity single-qubit gates in a strongly driven quantum dot hybrid qubit with charge noise
Yuan-Chi Yang, S. N. Coppersmith, Mark Friesen
Semiconductor double quantum dot hybrid qubits are promising candidates for high-fidelity quantum computing. However, their performance is limited by charge noise, which is ubiquit…
Reentrance of Topological Phase in Spin-1 Frustrated Heisenberg Chain
Yuan Yang, Shi-Ju Ran, Xi Chen +4
For the Haldane phase, the magnetic field usually tends to break the symmetry and drives the system into a topologically trivial phase. Here, we report a novel reentrance of the Ha…
Achieving High-Fidelity Single-Qubit Gates in a Strongly Driven Charge Qubit with Charge Noise
Yuan-Chi Yang, S. N. Coppersmith, Mark Friesen
Charge qubits formed in double quantum dots represent quintessential two-level systems that enjoy both ease of control and efficient readout. Unfortunately, charge noise can cause…
