Conditions for 3-partite and 4-partite genuine entanglement
Mark Hillery
A system of three or four particle can be entangled in a number of different ways. It may be the case that only subsets of the particles are entangled, and these subsets are not en…
Quantum Advantage in Identifying the Parity of Permutations with Certainty
Arnau Diebra, Santiago Llorens, David González-Lociga +4
We establish a sharp quantum advantage in determining the parity (even/odd) of an unknown permutation applied to any number of particles. Classically, this is impossible…
Interference and Measurement: Changing amplitude phase information to amplitude magnitude information
Pranjal Agarwal, Nada Ali, Mark Hillery
There are quantum procedures that encode the solutions to a problem in the phases of quantum amplitudes. This happens in some quantum optimization algorithms in which the value of…
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…
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…
Optimizing Initial State of Detector Sensors in Quantum Sensor Networks
Caitao Zhan, Himanshu Gupta, Mark Hillery
In this paper, we consider a network of quantum sensors, where each sensor is a qubit detector that "fires," i.e., its state changes when an event occurs close by. The change in st…
