Entanglement-assisted continuous-variable concatenated codes for encoding qubits or oscillators
Nihar Ranjan Dash, Sanjoy Dutta, R. Srikanth +1
Entanglement-assisted (EA) stabilizer codes enhance the rate of error correction in relation to codes with no pre-shared entanglement. Meanwhile, bosonic error-correcting codes, su…
Decoherence Mitigation with Local NOT Gates in Multipartite Systems
Venkat Abhignan, Raghav Sundararaman, Shriram Pragash M +2
We study the entanglement dynamics of -qubit Bell- and GHZ-type states under an amplitude-damping channel (ADC). We quantify multipartite entanglement using the genuine mu…
Twin-field-based multi-party quantum key agreement
Venkat Abhignan, R. Srikanth
Quantum key distribution (QKD) can secure cryptographic communication between two distant users, as guaranteed by the laws of quantum mechanics rather than computational assumption…
Protocols for counterfactual and twin-field quantum digital signature
Vinod N. Rao, Shrikant Utagi, Anirban Pathak +1
Quantum digital signature (QDS) is the quantum version of its classical counterpart, and can offer security against attacks of repudiation, signature forging and external eavesdrop…
