Abstract: Photonic integrated random unitary matrix generators based on multiport directional couplers are analyzed. Up to $512 \times 512$ matrix with complete Haar randomness is obtained by only ...

Define Z13 = A½Y(A½)H (A and Y are independent) and Z15 = B½Y(B½)H (B and Y are independent), where Y, A and B follow inverted complex Wishart, complex beta type I and complex beta type II ...

The New York Times recently warned its readers about a dangerous specter haunting the American republic: unitary executive theory. Alan Rappeport ominously wrote that the theory “rejects the idea that ...

WASHINGTON, Feb 14 (Reuters) - Donald Trump's broad assertions of power appear to be advancing an aggressive version of a legal doctrine called the "unitary executive" theory that envisions vast ...

Biclustering is a problem in machine learning and data mining that seeks to group together rows and columns of a dataset according to certain criteria. In this work, we highlight the natural relation ...

I encountered an issue when attempting to decompose the unitary matrix of QFT(4) using the built-in quantum_shannon_decomposition function in Cirq. According to the documentation, the ...

Quantum secret sharing (QSS) protocols without entanglement have showed high security by virtue of the characteristics of quantum mechanics. However, it is still a challenge to compare the security of ...
