Coherence Fraction in Grover Search Algorithm
Si-Qi Zhou, Hai Jin, Jin-Min Liang +3
The question of which resources drive the advantages in quantum algorithms has long been a fundamental challenge. While entanglement and coherence are critical to many quantum algo…
Trotterization is substantially efficient for low-energy states
Kaoru Mizuta, Tomotaka Kuwahara
Trotterization is one of the central approaches for simulating quantum many-body dynamics on quantum computers or tensor networks. In addition to its simple implementation, recent…
Macroscopic Particle Transport in Dissipative Long-Range Bosonic Systems
Hongchao Li, Cheng Shang, Tomotaka Kuwahara +1
Dissipation in quantum many-body systems provides a more general and experimentally realistic perspective on particle transport than closed quantum systems. In this work, we determ…
Low-loss polarization-maintaining router for single and entangled photons at a telecom wavelength
Pengfei Wang, Soyoung Baek, Masahiro Yabuno +3
Photon polarization serves as an essential quantum information carrier in quantum information and measurement applications. Routing of arbitrarily polarized single photons and pola…
Optimized Spectral Purity of Heralded Single Photons at the Telecom O-Band
Wu-Hao Cai, Soyoung Baek, Rui-Bo Jin +1
We report on optimizing the spectral purity of heralded single photons in the telecom O-band, where single photons can be propagated with low loss and low dispersion in a standard…
Q3DE: A fault-tolerant quantum computer architecture for multi-bit burst errors by cosmic rays
Yasunari Suzuki, Takanori Sugiyama, Tomochika Arai +3
Demonstrating small error rates by integrating quantum error correction (QEC) into an architecture of quantum computing is the next milestone towards scalable fault-tolerant quantu…
