Andreev qubit readout from dynamic interference supercurrent
Xian-Peng Zhang, Chuanchang Zeng, Zhen-Biao Yang +2
Nondemolition protocols use ancilla qubits to identify the fragile quantum state of a qubit without destroying its encoded information, thus playing a crucial role in nondestructiv…
Consecutive-gap ratio distribution for crossover ensembles
Gerson C. Duarte-Filho, Julian Siegl, John Schliemann +1
The study of spectrum statistics, such as the consecutive-gap ratio distribution, has revealed many interesting properties of many-body complex systems. Here we propose a two-param…
Compromise-Free Scaling of Qubit Speed and Coherence
Miguel J. Carballido, Simon Svab, Rafael S. Eggli +12
Across leading qubit platforms, a common trade-off persists: increasing coherence comes at the cost of operational speed, reflecting the notion that protecting a qubit from its noi…
Dual topological insulator with mirror symmetry protected helical edge states
Warlley H. Campos, Poliana H. Penteado, Julian Zanon +3
Dual topological insulators (DTIs) are simultaneously protected by time-reversal and crystal symmetries, representing advantageous alternatives to conventional topological insulato…
Two-site Kitaev sweet spots evolving into topological islands
Rodrigo A. Dourado, J. Carlos Egues, Poliana H. Penteado
Artificial Kitaev chains based on arrays of quantum dots are promising platforms for realizing Majorana Bound States (MBSs). In a two-site Kitaev chain, it is possible to find thes…
