“Building a Quantum Computer with Cat Codes
”
abstract:
A comprehensive
architectural analysis for a fault-tolerant quantum computer based on
cat codes concatenated with outer quantum error-correcting codes is
presented. The
construction significantly improves upon the fidelity of physical
Toffoli gates at very low qubit cost. To achieve even lower overheads,
a new magic-state distillation protocol for Toffoli states is devised. For
the physical hardware, we propose a system of acoustic resonators
coupled to superconducting circuits with a two-dimensional layout. We
find that with around 1,000 superconducting circuit components, one
could construct a fault-tolerant quantum computer that can run circuits
which are intractable for classical supercomputers. Hardware with 32,000
superconducting circuit components, in turn, could simulate the Hubbard
model in a regime beyond the reach of classical computing.”
