Simple Circuits for Exact Elimination of Leakage in a Qubit Embedded in a Three-level System
Yifan Sun, Junyi Zhang, Lian-Ao Wu
Leakage errors damage a qubit by coupling it to other levels. Over the years, several theoretical approaches to dealing with such errors have been developed based on perturbation a…
A quantum phase transition induced by a microscopic boundary condition
Jun Jing, Mike Guidry, Lian-Ao Wu
Quantum phase transitions are sudden changes in the ground-state wavefunction of a many-body system that can occur as a control parameter such as a concentration or a field strengt…
Control relaxation via dephasing: an exact quantum state diffusion study
Jun Jing, Ting Yu, Chi-Hang Lam +2
Dynamical decoupling as a quantum control strategy aims at suppressing quantum decoherence adopting the popular philosophy that the disorder in the unitary evolution of the open qu…
Non-Abelian holonomic transformation in the presence of classical noise
Jun Jing, Chi-Hang Lam, Lian-Ao Wu
It is proposed that high-speed universal quantum gates can be realized by using non-Abelian holonomic transformation. A cyclic evolution path which brings the system periodically b…
