Information complementarity in multipartite quantum states and security in cryptography
Anindita Bera, Asutosh Kumar, Debraj Rakshit +3
We derive complementarity relations for arbitrary quantum states of multiparty systems, of arbitrary number of parties and dimensions, between the purity of a part of the system an…

Order-from-disorder and critical scalings of spontaneous magnetization in random-field quantum spin systems
Anindita Bera, Debraj Rakshit, Maciej Lewenstein +3
We investigate the effect of a unidirectional quenched random field on the anisotropic quantum spin-1/2 model, which magnetizes spontaneously in the absence of the random fiel…
