Tunable Planar Josephson Junctions Driven by Time-Dependent Spin-Orbit Coupling
D. Monroe, M. Alidoust, I. Žutić·Aug 16, 2022
Integrating conventional superconductors with common III-V semiconductors provides a versatile platform to implement tunable Josephson junctions (JJs) and their applications. We propose that with gate-controlled time-dependent spin-orbit coupling, it...
Simulation of Interaction-Induced Chiral Topological Dynamics on a Digital Quantum Computer.
Jin Ming Koh, Tommy Tai, Ching Hua Lee·Jul 28, 2022
Chiral edge states are highly sought after as paradigmatic topological states relevant to both quantum information processing and dissipationless electron transport. Using superconducting transmon-based quantum computers, we demonstrate chiral topolo...
Optical realization of one-dimensionalgeneralized split-step quantum walks
P. A. A. Yasir, Abhaya S. Hegde, C. M. Chandrashekar·Jul 25, 2022
Quantum walks are more than tools for building quantum algorithms. They have been used effectively to model and simulate quantum dynamics in many complex physical processes. Particularly, a variant of discrete-time quantum walk known as split-step qu...
Parity-encoding-based quantum computing with Bayesian error tracking
Seok-Hyung Lee, S. Omkar, Yong-Siah Teo +1 more·Jul 14, 2022
Measurement-based quantum computing (MBQC) in linear optical systems is promising for near-future quantum computing architecture. However, the nondeterministic nature of entangling operations and photon losses hinder the large-scale generation of gra...
Conservation Laws and Quantum Error Correction: Toward a Generalized Matching Decoder
Benjamin J. Brown·Jul 13, 2022
Decoding algorithms are essential to fault-tolerant quantum-computing architectures. In this perspective we explore decoding algorithms for the surface code; a prototypical quantum low-density parity-check code that underlies many of the leading effo...

Bing Yao, Xiaohui Zhang, Hui Sun +3 more·Jul 7, 2022
The coming quantum computation is forcing us to reexamine the cryptosystems people use. We are applying graph colorings of topological coding to modern information security and future cryptography against supercomputer and quantum computer attacks in...
Long-distance coupling of spin qubits via topological magnons
Bence Het'enyi, A. Mook, J. Klinovaja +1 more·Jul 4, 2022
We consider two distant spin qubits in quantum dots, both coupled to a two-dimensional topological ferromagnet hosting chiral magnon edge states at the boundary. The chiral magnon is used to mediate entanglement between the spin qubits, realizing a f...
