Computational self-testing for entangled magic states
Akihiro Mizutani, Yuki Takeuchi, Ryo Hiromasa +2
In the seminal paper [Metger and Vidick, Quantum '21], they proposed a computational self-testing protocol for Bell states in a single quantum device. Their protocol relies on the…
Divide-and-conquer verification method for noisy intermediate-scale quantum computation
Yuki Takeuchi, Yasuhiro Takahashi, Tomoyuki Morimae +1
Several noisy intermediate-scale quantum computations can be regarded as logarithmic-depth quantum circuits on a sparse quantum computing chip, where two-qubit gates can be directl…
Variational secure cloud quantum computing
Yuta Shingu, Yuki Takeuchi, Suguru Endo +5
Variational quantum algorithms (VQAs) have been considered to be useful applications of noisy intermediate-scale quantum (NISQ) devices. Typically, in the VQAs, a parametrized ansa…
Anonymous quantum sensing
Hiroto Kasai, Yuki Takeuchi, Hideaki Hakoshima +2
A lot of attention has been paid to a quantum-sensing network for detecting magnetic fields in different positions. Recently, cryptographic quantum metrology was investigated where…
