Experimental Solutions to the High-Dimensional Mean King's Problem
Tareq Jaouni, Xiaoqin Gao, Sören Arlt +2
In 1987, Vaidman, Aharanov, and Albert put forward a puzzle called the Mean King's Problem (MKP) that can be solved only by harnessing quantum entanglement. Prime-powered solutions…
Full spatial characterization of entangled structured photons
Xiaoqin Gao, Yingwen Zhang, Alessio D'Errico +3

High-dimensional Encoding in the Round-Robin Differential-Phase-Shift Protocol
Mikka Stasiuk, Felix Hufnagel, Xiaoqin Gao +4
In quantum key distribution (QKD), protocols are tailored to adopt desirable experimental attributes, including high key rates, operation in high noise levels, and practical securi…
On the role of entanglement in qudit-based circuit compression
Xiaoqin Gao, Paul Appel, Nicolai Friis +2
Gate-based universal quantum computation is formulated in terms of two types of operations: local single-qubit gates, which are typically easily implementable, and two-qubit entang…
Manipulating the symmetry of transverse momentum entangled biphoton states
