The shape of higher-dimensional state space: Bloch-ball analog for a qutrit
Christopher Eltschka, Marcus Huber, Simon Morelli +1
Geometric intuition is a crucial tool to obtain deeper insight into many concepts of physics. A paradigmatic example of its power is the Bloch ball, the geometrical representation…
Pathways for entanglement based quantum communication in the face of high noise
Xiao-Min Hu, Chao Zhang, Yu Guo +10
Entanglement based quantum communication offers an increased level of security in practical secret shared key distribution. One of the fundamental principles enabling this security…
Autonomous Temporal Probability Concentration: Clockworks and the Second Law of Thermodynamics
Emanuel Schwarzhans, Maximilian P. E. Lock, Paul Erker +2
According to thermodynamics, the inevitable increase of entropy allows the past to be distinguished from the future. From this perspective, any clock must incorporate an irreversib…
Efficient generation of high-dimensional entanglement through multi-path downconversion
Xiao-Min Hu, Wen-Bo Xing, Bi-Heng Liu +5
High-dimensional entanglement promises to greatly enhance the performance of quantum communication and enable quantum advantages unreachable by qubit entanglement. One of the great…
Quantum key distribution overcoming extreme noise: simultaneous subspace coding using high-dimensional entanglement
Mirdit Doda, Marcus Huber, Gláucia Murta +3
High-dimensional entanglement promises to increase the information capacity of photons and is now routinely generated exploiting spatio-temporal degrees of freedom of single photon…
High-Dimensional Pixel Entanglement: Efficient Generation and Certification
Natalia Herrera Valencia, Vatshal Srivastav, Matej Pivoluska +4
Photons offer the potential to carry large amounts of information in their spectral, spatial, and polarisation degrees of freedom. While state-of-the-art classical communication sy…
