High photon-loss threshold quantum computing using GHZ-state measurements
Brendan Pankovich, Angus Kan, Kwok Ho Wan +5
We propose fault-tolerant architectures based on performing projective measurements in the Greenberger-Horne-Zeilinger (GHZ) basis on constant-sized, entangled resource states. We…

Memory-assisted decoder for approximate Gottesman-Kitaev-Preskill codes
Kwok Ho Wan, Alex Neville, W. S. Kolthammer
We propose a quantum error correction protocol for continuous-variable finite-energy, approximate Gottesman-Kitaev-Preskill (GKP) states undergoing small Gaussian random displaceme…

No imminent quantum supremacy by boson sampling
Alex Neville, Chris Sparrow, Raphaël Clifford +4
It is predicted that quantum computers will dramatically outperform their conventional counterparts. However, large-scale universal quantum computers are yet to be built. Boson sam…
