Non-CSS color codes on 2D lattices : Models and Topological Properties
Pramod Padmanabhan, Abhishek Chowdhury, Fumihiko Sugino +2
The two-dimensional color code is an alternative to the toric code that encodes more logical qubits while maintaining crucial features of the toric…
Novel quantum phases on graphs using abelian gauge theory
Pramod Padmanabhan, Fumihiko Sugino
Graphs are topological spaces that include broader objects than discretized manifolds, making them interesting playgrounds for the study of quantum phases not realized by symmetry…
Local invariants of braiding quantum gates -- associated link polynomials and entangling power
Pramod Padmanabhan, Fumihiko Sugino, Diego Trancanelli
For a generic -qubit system, local invariants under the action of characterize non-local properties of entanglement. In general, such properties a…
Generating W states with braiding operators
Pramod Padmanabhan, Fumihiko Sugino, Diego Trancanelli
Braiding operators can be used to create entangled states out of product states, thus establishing a correspondence between topological and quantum entanglement. This is well-known…
Highly entangled spin chains and 2D quantum gravity
Fumihiko Sugino
Motzkin and Fredkin spin chains exhibit the extraordinary amount of entanglement scaling as a square-root of the volume, which is beyond logarithmic scaling in the ordinary critica…
Braiding quantum gates from partition algebras
Pramod Padmanabhan, Fumihiko Sugino, Diego Trancanelli
Unitary braiding operators can be used as robust entangling quantum gates. We introduce a solution-generating technique to solve the -generalized Yang-Baxter equation, for…
