QKD in the NISQ era: enhancing secure key rates via quantum error correction
Shashank Kumar Ranu, Anil Prabhakar, Prabha Mandayam
Error mitigation is one of the key challenges in realising the full potential of quantum cryptographic protocols. Consequently, there is a lot of interest in adapting techniques fr…
Queue-Channel Capacities with Generalized Amplitude Damping
Vikesh Siddhu, Avhishek Chatterjee, Krishna Jagannathan +2
The generalized amplitude damping channel (GADC) is considered an important model for quantum communications, especially over optical networks. We make two salient contributions in…
Characterizing incompatibility of quantum measurements via their Naimark extensions
Arindam Mitra, Sibasish Ghosh, Prabha Mandayam
We obtain a formal characterization of the compatibility or otherwise of a set of positive-operator-valued measures (POVMs) via their Naimark extensions. We show that a set of POVM…
Finding good quantum codes using the Cartan form
Akshaya Jayashankar, Anjala M Babu, Hui Khoon Ng +1
We present a simple and fast numerical procedure to search for good quantum codes for storing logical qubits in the presence of independent per-qubit noise. In a key departure from…
Entanglement measures of bipartite quantum gates and their thermalization under arbitrary interaction strength
Bhargavi Jonnadula, Prabha Mandayam, Karol Życzkowski +1
Entanglement properties of bipartite unitary operators are studied via their local invariants, namely the entangling power and a complementary quantity, the gate typicality $…
The Classical Capacity of Additive Quantum Queue-Channels
Prabha Mandayam, Krishna Jagannathan, Avhishek Chatterjee
We consider a setting where a stream of qubits is processed sequentially. We derive fundamental limits on the rate at which classical information can be transmitted using qubits th…
