State learning from pairs of states
Pranjal Agarwal, Nada Ali, Camilla Polvara +3
Suppose you receive a sequence of qubits where each qubit is guaranteed to be in one of two pure states, but you do not know what those states are. Your task is to determine the st…

Discrete-outcome sensor networks: Multiple detection events and grouping detectors
Nada Ali, Mark Hillery
Quantum sensor networks have often been studied in order to determine how accurately they can determine a parameter, such as the strength of a magnetic field, at one of the detecto…

Can a qudit carry more information than a dit?
Teiko Heinosaari, Mark Hillery
Conventional wisdom suggests that within a fixed preparation-measurement setup, a qubit system offers no advantage over a bit. This indeed holds true when considering the standard…
