Quantum-Relaxation Based Optimization Algorithms: Theoretical Extensions
Kosei Teramoto, Rudy Raymond, Eyuri Wakakuwa +1
Quantum Random Access Optimizer (QRAO) is a quantum-relaxation based optimization algorithm proposed by Fuller et al. that utilizes Quantum Random Access Code (QRAC) to encode mult…
Testing Scalable Bell Inequalities for Quantum Graph States on IBM Quantum Devices
Bo Yang, Rudy Raymond, Hiroshi Imai +2
Testing and verifying imperfect multi-qubit quantum devices are important as such noisy quantum devices are widely available today. Bell inequalities are known useful for testing a…
Experimental Demonstration of Adaptive Quantum State Estimation
Ryo Okamoto, Minako Iefuji, Satoshi Oyama +4
The first experimental demonstration of an adaptive quantum state estimation (AQSE) is reported. The strong consistency and asymptotic efficiency of AQSE have been mathematically p…
Quantum network coding for quantum repeaters
Takahiko Satoh, Francois Le Gall, Hiroshi Imai
This paper considers quantum network coding, which is a recent technique that enables quantum information to be sent on complex networks at higher rates than by using straightforwa…
Experimental Realization of Optimal Noise Estimation for a General Pauli Channel
A. Chiuri, V. Rosati, G. Vallone +5
We present the experimental realization of the optimal estimation protocol for a Pauli noisy channel. The method is based on the generation of 2-qubit Bell states and the introduct…
Fourier Analytic Approach to Phase Estimation
Hiroshi Imai, Masahito Hayashi
For a unified analysis on the phase estimation, we focus on the limiting distribution. It is shown that the limiting distribution can be given by the absolute square of the Fourier…
