Robust encoding of a qubit in a molecule

VV Albert, JP Covey, J Preskill - Physical Review X, 2020 - APS
We construct quantum error-correcting codes that embed a finite-dimensional code space in
the infinite-dimensional Hilbert space of rotational states of a rigid body. These codes, which …

Multimode rotation-symmetric bosonic codes from homological rotor codes

Y Xu, Y Wang, VV Albert - Physical Review A, 2024 - APS
We develop quantum information processing primitives for the planar rotor, the state space
of a particle on a circle. The n-rotor Clifford group, U (1) n (n+ 1)/2⋊ GL n (Z), is represented …

Vacuum provides quantum advantage to otherwise simulatable architectures

C Calcluth, A Ferraro, G Ferrini - Physical Review A, 2023 - APS
We consider a computational model composed of ideal Gottesman-Kitaev-Preskill stabilizer
states, Gaussian operations including all rational symplectic operations and all real …
