The operator sum-difference representation for quantum maps: application to the two-qubit amplitude damping channel

S. Omkar, R. Srikanth, Subhashish Banerjee

On account of the Abel-Galois no-go theorem for the algebraic solution to quintic and higher order polynomials, the eigenvalue problem and the associated characteristic equation fo…

Beyond the Goldenberg-Vaidman protocol: Secure and efficient quantum communication using arbitrary, orthogonal, multi-particle quantum states

Chitra Shukla, Anirban Pathak, R. Srikanth

It is shown that maximally efficient protocols for secure direct quantum communications can be constructed using any arbitrary orthogonal basis. This establishes that no set of qua…

Two-step orthogonal-state-based protocol of quantum secure direct communication with the help of order-rearrangement technique

Preeti Yadav, R. Srikanth, Anirban Pathak

The Goldenberg-Vaidman (GV) protocol for quantum key distribution (QKD) uses orthogonal encoding states of a particle. Its security arises because operations accessible to Eve are…

Dissipative and Non-dissipative Single-Qubit Channels: Dynamics and Geometry

S. Omkar, R. Srikanth, Subhashish Banerjee

Single-qubit channels are studied under two broad classes: amplitude damping channels and generalized depolarizing channels. A canonical derivation of the Kraus representation of t…
