Exact Asymptotic Rates and an Exponential Strong Converse for quantum SMP and One-Way Communication
Daiki Suruga
Computing many instances jointly can reduce communication per instance. We ask whether such savings occur in the simultaneous-message-passing (SMP) model and how they depend on qua…

Another generalization of Hadamard test: Optimal sample complexities for learning functions on the unitary group
Daiki Suruga
Estimating properties of unknown unitary operations is a fundamental task in quantum information science. While full unitary tomography requires a number of samples to the unknown…
