Abstract
Disclosed herein is a protocol that enables the π/8-gate in chiral topological superconductors in which superconducting stiffness λ has been suppressed. The protocol enables a topologically protected π/8-gate in any pure Ising system that can be fabricated into genus=1 surface. By adding the π/8-gate to previously known techniques, a design for universal topologically protected quantum computation which may be implemented using rather conventional materials may be obtained.
Claims7
A method for implementing a π/8 gate in a genus=1 Ising system, the method comprising:
- providing a standard Ising qubit in a dynamical topology changing device (DTC);
- filling with a state X during a first time τ ∈[0, ⅔];
- measuring a charge |1> or |ψ> along a boundary of the DTC;
- and
- recording the measurement classically.
