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…
Quantum Phase Transitions and Localization in Semigroup Fredkin Spin Chain
Pramod Padmanabhan, Fumihiko Sugino, Vladimir Korepin
We construct an extended quantum spin chain model by introducing new degrees of freedom to the Fredkin spin chain. The new degrees of freedom called arrow indices are partly associ…
