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…
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…
Noise-induced collective quantum state preservation in spin qubit arrays
Edwin Barnes, Dong-Ling Deng, Robert E. Throckmorton +2
The hyperfine interaction with nuclear spins (or, Overhauser noise) has long been viewed as a leading source of decoherence in individual quantum dot spin qubits. Here we show that…
