Joint quasiprobability distribution on the measurement outcomes of MUB-driven operators
H S Smitha Rao, Swarnamala Sirsi, Karthik Bharath
We propose a method to define quasiprobability distributions for general spin- systems of dimension , where is a prime or power of prime. The method is based on a co…
Unsharp measurements, joint measurability and classical distributions for some qudits
H S Smitha Rao, Swarnamala Sirsi, Karthik Bharath
Classicality associated with joint measurability of operators manifests through a valid classical joint probability distribution on measurement outcomes. For qudits in dimension $n…
Mutually disjoint, maximally commuting set of physical observables for optimum state determination
H S Smitha Rao, Swarnamala Sirsi, Karthik Bharath
We consider the state determination problem using Mutually Unbiased Bases(MUBs). For spin-1, spin-3/2 and spin-2 systems, analogous to Pauli operators of spin-1/2 system, which are…
Geometric Multiaxial Representation of N-qubit Mixed Symmetric Separable States
Suma SP, Swarnamala Sirsi, Subramanya Hegde +1
Study of an N qubit mixed symmetric separable states is a long standing challenging problem as there exist no unique separability criterion. In this regard, we take up the N-qubit…
POVM construction: a simple recipe with applications to symmetric states
Swarnamala Sirsi, Karthik Bharath, S. P. Shilpashree
We propose a simple method for constructing POVMs using any set of matrices which form an orthonormal basis for the space of complex matrices. Considering the orthonormal set of ir…
Local Unitary Equivalent Classes of Symmetric N-Qubit Mixed States
Sakineh Ashourisheikhi, Swarnamala Sirsi
Majorana Representation (MR) of symmetric -qubit pure states has been used successfully in entanglement classification. Generalization of this has been a long standing open pr…
