Disorder signatures emerging at millikelvin temperatures in Si/SiGe field-effect stacks
Lino Visser, Alberto Mistroni, Yuji Yamamoto +9
The performance and scalability of electron spin qubits based on gate-defined quantum-dots in undoped Si/SiGe field-effect stacks remain constrained by disorder originating from th…

Bit-Flip Vulnerability of Shared KV-Cache Blocks in LLM Serving Systems
Yuji Yamamoto, Satoshi Matsuura
Rowhammer on GPU DRAM has enabled adversarial bit flips in model weights; shared KV-cache blocks in LLM serving systems present an analogous but previously unexamined target. In vL…
