This paper shows a concept for parallelization of double Divide and Conquer and its preliminary result. For singular value decomposition, double Divide and Conquer was recently proposed. It first computes singular values by a compact version of Divide and Conquer. The corresponding singular vectors are then computed by twisted factorization. The speed and accuracy of double Divide and Conquer a...

We present a divide-and-conquer approach to deterministically prepare Dicke states |Dkn> (i.e. equal-weight superpositions of all n-qubit with Hamming Weight k) on quantum computers. In an experimental evaluation for up n=6 qubits IBM Quantum Sydney and Montreal devices, we achieve significantly higher state fidelity compared previous results [Mukherjee et.al. TQE'2020, Cr...

Parliamentary elections often result in the formation of a coalition government. While legislative process allows actors within government to monitor each other, little attention has focused on how opposition parties respond We argue that have incentives uncover and highlight differences tensions governing coalition. A strategy by use tools policy conflicts ministerial drift increases intra-coa...
