One Qubit Can Beat One Bit: Quantum Advantage for Post-Training Quantization
Yuma Ichikawa, Moeto Mishima
One-bit post-training quantization represents each weight using only its sign, requiring all deployment contexts to share the same binary weight matrix even when their activation s…

Adaptive Window Decoding based on Spatiotemporal Complementary Gap
Moeto Mishima, Riki Toshio, Kaito Kishi +4
Real-time decoding plays a crucial role in practical fault-tolerant quantum computing. Window decoding, in which the decoding problem is divided into windows, is a promising approa…

Single-shot single-mode optical two-parameter displacement estimation beyond classical limit
Fumiya Hanamura, Warit Asavanant, Seigo Kikura +8
Uncertainty principle prohibits the precise measurement of both components of displacement parameters in phase space. We have theoretically shown that this limit can be beaten usin…
