Groupoid Toric Codes
Pramod Padmanabhan, Indrajit Jana
The toric code can be constructed as a gauge theory of finite groups on oriented two dimensional lattices. Here we construct analogous models with the gauge fields belonging to gro…
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…
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…
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…
Quantum entanglement, supersymmetry, and the generalized Yang-Baxter equation
Pramod Padmanabhan, Fumihiko Sugino, Diego Trancanelli
Entangled states, such as the Bell and GHZ states, are generated from separable states using matrices known to satisfy the Yang-Baxter equation and its generalization. This remarka…
