Quantum realization of arbitrary joint measurability structures
Ravi Kunjwal, Chris Heunen, Tobias Fritz
In many a traditional physics textbook, a quantum measurement is defined as a projective measurement represented by a Hermitian operator. In quantum information theory, however, th…

Relative volume of separable bipartite states
Rajeev Singh, Ravi Kunjwal, R. Simon
Every choice of an orthonormal frame in the d-dimensional Hilbert space of a system corresponds to one set of all mutually commuting density matrices or, equivalently, a classical…

Minimal state-dependent proof of measurement contextuality for a qubit
Ravi Kunjwal, Sibasish Ghosh
We show that three unsharp binary qubit measurements are enough to violate a generalized noncontextuality inequality, the LSW inequality, in a state-dependent manner. For the case…
