Simplification of tensor updates toward performance-complexity balanced quantum computer simulation
Koichi Yanagisawa, Tsuyoshi Okubo, Shota Koshikawa +3
Matrix Product States (MPS) provide a powerful framework for simulating quantum circuits. In practical simulations, tensor updates are typically performed in the canonical form (CF…

Perfect impedance matching unlocks sensitive radio-frequency reflectometry in 2D material quantum dots
Motoya Shinozaki, Akitomi Shirachi, Yuta Kera +7
Two-dimensional (2D) materials are attractive platforms for realizing high-performance quantum bits (qubits). However, radio-frequency (RF) charge detection, which is a key techniq…

Hyperbolic Floquet code with graph-edge syndromes
Hideyuki Ozawa, Isamu Kudo, Yuki Takeuchi +1
Quantum error correction would be a primitive for demonstrating quantum advantage in a realistic noisy environment. Floquet codes are a class of dynamically generated, stabilizer-b…
