Black holes as clouded mirrors: the Hayden-Preskill protocol with symmetry
Yoshifumi Nakata, Eyuri Wakakuwa, Masato Koashi
The Hayden-Preskill protocol is a qubit-toy model of the black hole information paradox. Based on the assumption of scrambling, it was revealed that quantum information is instantl…
Polylog-overhead highly fault-tolerant measurement-based quantum computation: all-Gaussian implementation with Gottesman-Kitaev-Preskill code
Hayata Yamasaki, Kosuke Fukui, Yuki Takeuchi +2
Scalability of flying photonic quantum systems in generating quantum entanglement offers a potential for implementing large-scale fault-tolerant quantum computation, especially by…
Finite-size security of continuous-variable quantum key distribution with digital signal processing
Takaya Matsuura, Kento Maeda, Toshihiko Sasaki +1
In comparison to conventional discrete-variable (DV) quantum key distribution (QKD), continuous-variable (CV) QKD with homodyne/heterodyne measurements has distinct advantages of l…
Learning with Optimized Random Features: Exponential Speedup by Quantum Machine Learning without Sparsity and Low-Rank Assumptions
Hayata Yamasaki, Sathyawageeswar Subramanian, Sho Sonoda +1
Kernel methods augmented with random features give scalable algorithms for learning from big data. But it has been computationally hard to sample random features according to a pro…
