Catalyst towers can lower runtime and spacetime cost at smaller code distances
What the study found Catalyst towers, a technique for implementing continuous rotations in a surface code, can reduce runtime and, at small and medium code distances, can also decrease the total spacetime volume of rotations. At large code distances, the study says conventional Clifford+T synthesis may be more efficient. Why the authors say this matters…
Multilayer superconducting hardware can place and route qLDPC codes
What the study found The study found that a hardware-aware layout method called HAL can automate and optimize the placement and routing of arbitrary quantum low-density parity-check (qLDPC) codes in multilayer superconducting hardware. The authors also report that they generated around 150 explicit qLDPC code layouts and identified code designs with competitive tradeoffs between hardware…
