Subsequence Analysis Problems for Binary Parikh Matrices
Szilárd Zsolt Fazekas, Xinhao Huang, Robert Mercaş
The universality index corresponding to a word is the largest integer k such that every word of length k over the given alphabet occurs in it as a subsequence. Relative to language…
Deterministic Bandwidth of Finite Languages
Da-Jung Cho, Szilárd Zsolt Fazekas, Max Wiedenhöft
Bandwidth restricts how far transitions can move under an ordering of the states in an automaton. While every finite language admits a bandwidth-2 NFA representation, the determini…
Measurement-only circuit of perturbed toric code on triangular lattice: Topological entanglement, 1-form symmetry and logical qubits
Keisuke Kataoka, Yoshihito Kuno, Takahiro Orito +1
Measurement-only (quantum) circuit (MoC) gives possibility to realize the states with rich entanglements, topological orders and quantum memories. This work studies the MoC, in whi…
Disordered purification phase transition in hybrid random circuits
Kengo Anzai, Hiroaki Matsueda, Yoshihito Kuno
Noise is inevitable in realistic quantum circuits. It arises randomly in space. Inspired by spatial non-uniformity of the noise, we investigate the effects of spatial modulation on…
Jump Complexity of Deterministic Finite Automata with Translucent Letters
Szilárd Zsolt Fazekas, Victor Mitrana, Andrei Păun +1
We investigate a dynamical complexity measure defined for finite automata with translucent letters (FAwtl). Roughly, this measure counts the minimal number of necessary jumps for s…
Strong and weak symmetries and their spontaneous symmetry breaking in mixed states emerging from the quantum Ising model under multiple decoherence
Takahiro Orito, Yoshihito Kuno, Ikuo Ichinose
Discovering and categorizing quantum orders in mixed many-body systems are currently one of the most important problems. Specific types of decoherence applied to typical quantum ma…
