Exponential Lifetime Improvement in Topological Quantum Memories
Charles-Edouard Bardyn, Torsten Karzig
We propose a simple yet efficient mechanism for passive error correction in topological quantum memories. Our scheme relies on driven-dissipative ancilla systems which couple to lo…
A geometric protocol for a robust Majorana magic gate
Torsten Karzig, Yuval Oreg, Gil Refael +1
A universal quantum computer requires a full set of basic quantum gates. With Majorana bound states one can form all necessary quantum gates in a topologically protected way, bar o…
Topological polaritons from photonic Dirac cones coupled to excitons in a magnetic field
Kexin Yi, Torsten Karzig
We introduce an alternative scheme for creating topological polaritons (topolaritons) by exploiting the presence of photonic Dirac cones in photonic crystals with triangular lattic…
Langevin dynamics of a heavy particle and orthogonality effects
Mark Thomas, Torsten Karzig, Silvia Viola Kusminskiy
The dynamics of a classical heavy particle moving in a quantum environment is determined by a Langevin equation which encapsulates the effect of the environment-induced reaction fo…
Chiral Bogoliubons in Nonlinear Bosonic Systems
Charles-Edouard Bardyn, Torsten Karzig, Gil Refael +1
We present a versatile scheme for creating topological Bogoliubov excitations in weakly interacting bosonic systems. Our proposal relies on a background stationary field that consi…
Shortcuts to nonabelian braiding
Torsten Karzig, Falko Pientka, Gil Refael +1
Topological quantum information processing relies on adiabatic braiding of nonabelian quasiparticles. Performing the braiding operations in finite time introduces transitions out o…
