Quantum Port: Gamification of quantum teleportation for public engagement

Pak Shen Choong, Aqilah Rasat, Afiqa Nik Aimi +1

Concepts on quantum physics are generally difficult for the general public to understand and grasp due to its counter-intuitive nature and requirement for higher level of mathemati…

Evaluating Pauli errors on cluster states by weighted distances

Choong Pak Shen, Davide Girolami

We address the problem of evaluating the difference between quantum states before and after being affected by errors encoded in unitary transformations. Standard distance functions…

Special core tensors of multi-qubit states and the concurrency of three lines

Pak Shen Choong, Hishamuddin Zainuddin, Kar Tim Chan +1

Classification of multipartite states aims to obtain a set of operationally useful and finite entanglement classes under the action of either local unitary (LU) or stochastic local…

Higher order singular value decomposition and the reduced density matrices of three qubits

P. S. Choong, H. Zainuddin, K. T. Chan +1

In this paper, we demonstrate that higher order singular value decomposition (HOSVD) can be used to identify special states in three qubits by local unitary (LU) operations. Since…
