Probing chiral topological states with permutation defects
Yarden Sheffer, Ruihua Fan, Ady Stern +2
The hallmark of two-dimensional chiral topological phases is the existence of anomalous gapless modes at the spatial boundary. Yet, the manifestation of this edge anomaly within th…
Extracting topological spins from bulk multipartite entanglement
Yarden Sheffer, Ady Stern, Erez Berg
We address the problem of identifying a 2+1d topologically ordered phase using measurements on the ground-state wavefunction. For non-chiral topological order, we describe a series…
Realizing string-net condensation: Fibonacci anyon braiding for universal gates and sampling chromatic polynomials
Zlatko K. Minev, Khadijeh Najafi, Swarnadeep Majumder +5
The remarkable complexity of the vacuum state of a topologically-ordered many-body quantum system encodes the character and intricate braiding interactions of its emergent particle…
Preparing topological states with finite depth simultaneous commuting gates
Yarden Sheffer, Erez Berg, Ady Stern
We present protocols for preparing two-dimensional abelian and non-abelian topologically ordered states by employing finite depth unitary circuits composed of long-ranged, simultan…
