Decoherence-suppressed nonadiabatic holonomic quantum computation

Nonadiabatic Holonomic Quantum Computation Based on Rydberg Ground State Blockade

“…[44,45] Additionally, for quantum computation schemes that rely on excited states as ancillary states, the decay of the excited state undoubtedly leads to decoherence and increases the infidelity. [46] Experimentally, Zhou et al have observed the ground-state geometric phase in the threespin 𝑋𝑌 model. [47] The ground-state blockade has been observed [48] and designed to achieve a two-qubit quantum logic gate based on the Abelian geometric phase [49] as well as the quantum entanglement.…”

“…In a relevant paper, [46] decoherence-suppressed nonadiabatic holonomic quantum computation scheme is proposed, which can greatly suppress the population of the excited state so that it is of inherent robustness to the system decay. We can compare this scheme and the scheme in the relevant paper.…”
