Decoherence of two coupled singlet-triplet spin qubits
Yang-Le Wu, S. Das Sarma
We study a pair of capacitively coupled singlet-triplet spin qubits. We characterize the two-qubit decoherence through two complementary measures, the decay time of coupled-qubit o…
Intrinsic decoherence in isolated quantum systems
Yang-Le Wu, Dong-Ling Deng, Xiaopeng Li +1
We study the intrinsic, disorder-induced decoherence of an isolated quantum system under its own dynamics. Specifically, we investigate the characteristic time scale (i.e., the dec…
Statistical Bubble Localization with Random Interactions
Xiaopeng Li, Dong-Ling Deng, Yang-Le Wu +1
We study one-dimensional spinless fermions with random interactions, but without any on-site disorder. We find that random interactions generically stabilize a many-body localized…
Logarithmic Entanglement Lightcone in Many-Body Localized Systems
Dong-Ling Deng, Xiaopeng Li, J. H. Pixley +2
We theoretically study the response of a many-body localized system to a local quench from a quantum information perspective. We find that the local quench triggers entanglement gr…
Dynamics of two coupled semiconductor spin qubits in a noisy environment
S. Das Sarma, Robert E. Throckmorton, Yang-Le Wu
We theoretically consider the temporal dynamics of two coupled spin qubits (e.g., semiconductor quantum dots) driven by the inter-qubit spin-spin coupling. The presence of environm…
The enigmatic 12/5 fractional quantum Hall effect
Kiryl Pakrouski, Matthias Troyer, Yang-Le Wu +2
We numerically study the fractional quantum Hall effect at filling factors and 13/5 (the particle-hole conjugate of 12/5) in high-quality two-dimensional GaAs heterostruct…
