Simulating the Dynamics of Markovian Quantum Processes by Quantum Collision Models on Quantum Computers

Zeqing Wang, Julian D. Teske, Anshuman Bhardwaj +2

Hamiltonian dynamics have been widely implemented on noisy intermediate-scale quantum devices in recent years. In contrast, experimental demonstrations of Markovian quantum dynamic…

Impurity quadrupole moments as local probes of flux sectors in the Kitaev spin liquid

Masahiro O. Takahashi, Wen-Han Kao, Satoshi Fujimoto +1

Emergent fluxes play a central role in the low-energy properties of quantum spin liquids (QSLs), where they encode the underlying gauge structure and fractionalization of spins. He…

Signatures of Non-Abelian Kitaev quantum spin liquids in noise magnetormetry

Xiao Xiao, Masahiro O. Takahashi, Paul Stevenson +2

Identification of isolated Majorana zero modes (MZMs) is a key step towards the realization of fault-tolerant topological quantum computation. Here we show how the -based nois…

flux binding to higher-spin impurities in the Kitaev spin liquid

Masahiro O. Takahashi, Wen-Han Kao, Satoshi Fujimoto +1

Stabilizing fluxes in Kitaev spin liquids (KSLs) is crucial for both characterizing candidate materials and identifying Ising anyons. In this study, we investigate the effect…

Imaging quantum interference in a monolayer Kitaev quantum spin liquid candidate

Y. Kohsaka, S. Akutagawa, S. Omachi +16

Single atomic defects are prominent windows to look into host quantum states because collective responses from the host states emerge as localized states around the defects. Friede…
