Magic state distillation with low overhead
Did you know?
Web22 mrt. 2024 · The protocol can be modified to distill magic states for other gates at the third level of the Clifford hierarchy, with the same asymptotic performance. The protocol relies on the construction of weakly self-dual CSS codes with many logical qubits and large distance, allowing us to implement control-SWAPs on multiple qubits. WebWe propose a family of error-detecting stabilizer codes with an encoding rate of 1/3 that permit a transversal implementation of the gate T=exp(-iπZ/8) on all logical qubits. These codes are used to construct protocols for distilling high-quality “magic” states T+ by Clifford group gates and Pauli measurements. The distillation overhead scales as …
