Geometric and holonomic quantum computation
Jiang Zhang, Thi Ha Kyaw, Stefan Filipp +3
Geometric and holonomic quantum computation utilizes intrinsic geometric properties of quantum-mechanical state spaces to realize quantum logic gates. Since both geometric phases a…
Topological Dynamical Decoupling
Jiang Zhang, Xiao-Dong Yu, Gui-Lu Long +1
We show that topological equivalence classes of circles in a two-dimensional square lattice can be used to design dynamical decoupling procedures to protect qubits attached on the…
Nonadiabatic holonomic quantum computation on coupled transmons with ancillaries
Tao Chen, Jiang Zhang, Zheng-Yuan Xue
The physical implementation of holonomic quantum computation is challenging due to the needed complex controllable interactions in multilevel quantum systems. Here we propose to im…
Protection of Logical Qubits via Optimal State Transfers
Jiang Zhang, Zheng-Yang Zhou, Lian-Ao Wu +1
Dynamical decoupling can enforce a symmetry on the dynamics of an open quantum system. Here we develop an efficient dynamical-decoupling-based strategy to create the decoherence-fr…
Holonomic Surface Codes for Fault-Tolerant Quantum Computation
Jiang Zhang, Simon J. Devitt, J. Q. You +1
Surface codes can protect quantum information stored in qubits from local errors as long as the per-operation error rate is below a certain threshold. Here we propose holonomic sur…
Holonomic quantum computation in the ultrastrong-coupling regime of circuit QED
Yimin Wang, Jiang Zhang, Chunfeng Wu +2
We present an experimentally feasible scheme to implement holonomic quantum computation in the ultrastrong-coupling regime of light-matter interaction. The large anharmonicity and…
