NonHermitian Topological Phases in a Hermitian Modified Bosonic Kitaev Chain
Raditya Weda Bomantara, Ibsal Assi, J. P. F. LeBlanc +1
We present a modification to the bosonic Kitaev chain that, despite being Hermitian, supports both nonHermitian skin effect and nontrivial topological edge modes in its excitation…
Generating non-Clifford gate operations through exact mapping between Majorana fermions and parafermions
Ali Hamed Safwan, Raditya Weda Bomantara
Majorana fermions and their generalizations to parafermions are considered promising building blocks of fault-tolerant quantum computers for their ability to encode…
A Robust Large-Period Discrete Time Crystal and its Signature in a Digital Quantum Computer
Tianqi Chen, Ruizhe Shen, Ching Hua Lee +2
Discrete time crystals (DTCs) are novel out-of-equilibrium quantum states of matter which break time translational symmetry. DTCs have been extensively realized in experiments, par…
Topological modes and beyond
Weiwei Zhu, Jiangbin Gong, Raditya Weda Bomantara
This short Perspective article presents an overview of the discovery of topological modes as well as their physical significance in quantum computing and the understanding of a…
parafermion modes in interacting periodically driven superconducting chain
Raditya Weda Bomantara
We theoretically report the emergence of parafermion edge modes in a periodically driven spinful superconducting chain with modest fermionic Hubbard interaction. These parafe…
Nonlocal discrete time crystals in periodically driven surface codes
Raditya Weda Bomantara
Discrete time crystals (DTCs) are nonequilibrium phases of matter characterized by robust subharmonic order parameter dynamics. We report a new type of DTC in a periodically driven…
