Majority-Agreed Key Distribution using Absolutely Maximally Entangled Stabilizer States
Sowrabh Sudevan, Ramij Rahaman, Sourin Das
In [Phys. Rev. A 77, 060304(R),(2008)], Facchi et al. introduced absolutely maximally entangled (AME) states and also suggested ``majority-agreed key distribution"(MAKD) as a possi…

Codeword Stabilized Codes from m-Uniform Graph States
Sowrabh Sudevan, Sourin Das, Thamadathil Aswanth +2
An m-uniform quantum state on n qubits is an entangled state in which every m-qubit subsystem is maximally mixed. Starting with an m-uniform state realized as the graph state assoc…

Multipartite entanglement and quantum error identification in -dimensional cluster states
Sowrabh Sudevan, Daniel Azses, Emanuele G. Dalla Torre +2
An entangled state is said to be -uniform if the reduced density matrix of any qubits is maximally mixed. This is intimately linked to pure quantum error correction codes (Q…
