New work on "Symmetric Channel Verification," a general framework lifting (virtual) error detection and correction to channel level. Prominently, it breaks barrier of existing QEM; symmetry-breaking noise under arbitrary input states. Congrats Kento! arxiv.org/abs/2503.13114

An algorithm with sublinear resource scaling in the number of observables and Heisenberg-limited precision brings quantum-enhanced measurements of multiple observables within reach. Kaito Wada Nobuyuki Yoshioka go.aps.org/4llRc5z

Paper out! Contrary to the common understanding, we prove that randomness generation is barely hurt by the choice of randomizers, covering brickwork circuit in lattices to patchwork circuits. Congrats Toshihiro for the thorough work! arxiv.org/abs/2504.07390

Happy to see the seminal work published in PRX Quantum. Thank you very much for the great collaboration Kaito Wada and Naoki Yamamoto! journals.aps.org/prxquantum/abs…

Is entire noise learning needed for unbiased QEM? Surprisingly, only knowing total error rate suffices; sample errors, then invert noise. This is robust to spacial AND temporal correlation. Thank you Haipeng and Ying for super exciting collaboration! arxiv.org/abs/2504.12864

Paper out! We prove worst-case classical hardness of sampling from unitary cluster Jastrow circuit, which automatically proves hardness for well-known UCC families. Congrats Hafid-san, Iwakiri-san, Kohda-san, and Kento for important step for QSCI/SQD! arxiv.org/abs/2504.12893

Thrilled to share that seminal works on unitary designs of symmetric local random circuits have been published jointly in PRL and PRA. Yosuke Mitsuhashi will give a talk at TQC 2025. Don't miss it! journals.aps.org/prl/abstract/1…
