Space‐Efficient Logical Qubit Architecture with a Bus for Magic State Consumption
Advanced Quantum Technologies, EarlyView.This paper proposes a logical qubit architecture, considering the consumption of magic states. By constructing the patch to the magic state using the repetition code and data qubits using the surface code, the proposed architecture minimizes the number of qubits, referred to as the space cost.

Fused Collapsing for Wide BVH Construction
Computer Graphics Forum, EarlyView.Abstract We propose a novel approach for constructing wide bounding volume hierarchies on the GPU by integrating a simple bottom‐up collapsing procedure within an existing binary bottom‐up BVH builder. Our approach directly constructs a wide BVH without traversing a temporary binary BVH as done by previous approaches and achieves 1.4 – 1.6 × lower ...
