A degree-\(R\) phase gate can now be approximated with interaction time scaling as \(O(log^{(R-1)/2+o}(1/ε))\), a marked improvement on previous methods requiring either O(1/ε) or O(log(1/ε)) time. This polylogarithmic scaling represents a demonstrably faster route to high precision gates in continuous-variable quantum computation. Establishing this efficiency unlocks new potential for applications like bosonic simulation and solving complex differential equations.
