  author={Dawn Chen and Jun Jing},

In the quantum computation scenario, geometric phase-gates are becoming increasingly attractive due to their supposed intrinsic fault tolerance. In an adiabatic cyclic evolution, Berry phase appears to realize a geometric transformation. Performing the quantum gates as many as possible within the timescale of coherence, however, remains an inconvenient bottleneck due to the systematic errors. Here we propose an accelerated adiabatic quantum gate based on the Berry phase, the transitionless…

Suppressing the geometric dephasing of Berry phase by using modified dynamical decoupling sequences

Even though traditional dynamical decoupling methods have the ability to resist dynamic dephasing caused by low frequency noise, they are not appropriate for suppressing the residual geometric

Nonadiabatic geometric quantum computation

A different way to realize nonadiabatic geometric quantum computation is proposed by varying parameters in the Hamiltonian for nuclear-magnetic resonance, where the dynamical and geometric phases are

Continuous-variable geometric phase and its manipulation for quantum computation in a superconducting circuit

The geometric approach allows for one-step implementation of n-qubit controlled-phase gates, which represents a remarkable advantage compared to gate decomposition methods, where the number of required steps dramatically increases with n.

By using a newly designed sequence of simple operations with an additional vertical magnetic field, the conditional geometric phase shift gate can be run nonadiabatically and geometric quantum computation can be done at the same rate as usual quantum computation.

In holonomic quantum computation, single-qubit gates are performed using driving protocols that trace out closed loops on the Bloch sphere, making them robust to certain pulse errors. However,
