Optimal quantum tomography with constrained elementary measurements arising from unitary bases

S. Chaturvedi, Sibasish Ghosh, K. R. Parthasarathy +1

The purpose of this paper is to introduce techniques of obtaining optimal ways to determine a d-level quantum state or distinguish such states. It entails designing constrained ele…

Entanglement properties of positive operators with ranges in completely entangled subspaces

R Sengupta, Arvind, Ajit Iqbal Singh

We prove that the projection on a completely entangled subspace S of maximum dimension in a multipartite quantum system obtained by Parthasarathy is not positive under partial tran…

Persistent entanglement in a class of eigenstates of quantum Heisenberg spin glasses

Arun Kannawadi, Auditya Sharma, Arul Lakshminarayan

The eigenstates of a quantum spin glass Hamiltonian with long-range interaction are examined from the point of view of localisation and entanglement. In particular, low particle se…
