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 $…
On optimal cloning and incompatibility
Arindam Mitra, Prabha Mandayam
We investigate the role of symmetric quantum cloning machines (QCMs) in quantifying the mutual incompatibility of quantum observables. Specifically, we identify a cloning-based inc…
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…
Differential phase encoded measurement-device-independent quantum key distribution
Shashank Kumar Ranu, Anil Prabhakar, Prabha Mandayam
We present a measurement-device-independent quantum key distribution (MDI-QKD) using single photons in a linear superposition of three orthogonal time-bin states, for generating th…
