Authentication in Quantum Networks
Christopher Battarbee, Suchetana Goswami, Elham Kashefi +1
In this review, we survey the cryptographic task of authentication from the perspective of quantum communication. We review three main flavours of authentication that are often con…
Entanglement of minimal dimension and a class of local state discrimination problems
Saronath Halder, Suchetana Goswami
In this work, we construct small sets of bipartite orthogonal pure states that cannot be perfectly distinguished by local operations and classical communication (LOCC). We mention…
Hybrid Authentication Protocols for Advanced Quantum Networks
Suchetana Goswami, Mina Doosti, Elham Kashefi
Authentication is a fundamental building block of secure quantum networks, essential for quantum cryptographic protocols and often debated as a key limitation of quantum key distri…
Non-Markovian noise limits for sustaining entanglement in multiparty quantum states
Suchetana Goswami, Ujjwal Sen
The principal resource in several quantum information processing tasks is entanglement. Building practically useful versions of such tasks, one often needs to consider multipartite…
