Characterizing gate operations near the sweet spot of an exchange-only qubit
Jianjia Fei, Jo-Tzu Hung, Teck Seng Koh +4
Optimal working points or "sweet spots" have arisen as an important tool for mitigating charge noise in quantum dot logical spin qubits. The exchange-only qubit provides an ideal s…

Numerical Computations of Separability Probabilities
Jianjia Fei, Robert Joynt
We compute the probability that a bipartite quantum state is separable by Monte Carlo sampling. This is carried out for rebits, qubits and quaterbits. We sampled …

Decoherence of an exchange qubit by hyperfine interaction
Jo-Tzu Hung, Jianjia Fei, Mark Friesen +1
We study three-electron-spin decoherence in a semiconductor triple quantum dot with a linear geometry. The three electron spins are coupled by exchange interactions J_{12} and J_{2…
