Observation of the non-Hermitian skin effect and Fermi skin on a digital quantum computer
Ruizhe Shen, Tianqi Chen, Bo Yang +1
Non-Hermitian physics has attracted considerable attention in recent years, particularly the non-Hermitian skin effect (NHSE) for its extreme sensitivity and non-locality. While th…
Higher-order protection of quantum gates: Hamiltonian engineering coordinated with dynamical decoupling
P. Z. Zhao, Tianqi Chen, Sirui Liu +1
Dynamical decoupling represents an active approach towards the protection of quantum memories and quantum gates. Because dynamical decoupling operations can interfere with a system…
Efficient preparation of the AKLT State with Measurement-based Imaginary Time Evolution
Tianqi Chen, Tim Byrnes
Quantum state preparation plays a crucial role in several areas of quantum information science, in applications such as quantum simulation, quantum metrology and quantum computing.…
A Robust Large-Period Discrete Time Crystal and its Signature in a Digital Quantum Computer
Tianqi Chen, Ruizhe Shen, Ching Hua Lee +2
Discrete time crystals (DTCs) are novel out-of-equilibrium quantum states of matter which break time translational symmetry. DTCs have been extensively realized in experiments, par…
