Registered Attribute-Based Encryption with Publicly Verifiable Certified Deletion, Everlasting Security, and More
Shayeef Murshid, Ramprasad Sarkar, Mriganka Mandal
Certified deletion ensures that encrypted data can be irreversibly deleted, preventing future recovery even if decryption keys are later exposed. Although existing works have achie…
Local strategies are pretty good at computing Boolean properties of quantum sequences
Tathagata Gupta, Ankith Mohan, Shayeef Murshid +3
Quantum memory is a scarce and costly resource, yet little is known about which learning tasks remain feasible under severe memory constraints. We study the problem of computing gl…
Quantum nonlocality without entanglement and state discrimination measures
Shayeef Murshid, Tathagata Gupta, Vincent Russo +1
An ensemble of product states is said to exhibit "quantum nonlocality without entanglement" if it cannot be optimally discriminated using local operations and classical communicati…
Optimal discrimination of quantum sequences
Tathagata Gupta, Shayeef Murshid, Vincent Russo +1
A key concept of quantum information theory is that accessing information encoded in a quantum system requires us to discriminate between several possible states the system could b…
