Exploring Energy-Time Entanglement Using Geometric Phase
Anand Kumar Jha, Mehul Malik, Robert W. Boyd
Using the signal and idler photons produced by parametric downconversion, we report an experimental observation of a violation of the Bell inequality for energy and time based pure…
Measurements in two bases are sufficient for certifying high-dimensional entanglement
Jessica Bavaresco, Natalia Herrera Valencia, Claude Klöckl +5
High-dimensional encoding of quantum information provides a promising method of transcending current limitations in quantum communication. One of the central challenges in the purs…
Layered Quantum Key Distribution
Matej Pivoluska, Marcus Huber, Mehul Malik
We introduce a family of QKD protocols for distributing shared random keys within a network of users. The advantage of these protocols is that any possible key structure needed…
Experimental GHZ Entanglement beyond Qubits
Manuel Erhard, Mehul Malik, Mario Krenn +1
The Greenberger-Horne-Zeilinger (GHZ) argument provides an all-or-nothing contradiction between quantum mechanics and local-realistic theories. In its original formulation, GHZ inv…
Generation of the Complete Four-dimensional Bell Basis
Feiran Wang, Manuel Erhard, Amin Babazadeh +3
The Bell basis is a distinctive set of maximally entangled two-particle quantum states that forms the foundation for many quantum protocols such as teleportation, dense coding and…
High-Dimensional Single-Photon Quantum Gates: Concepts and Experiments
Amin Babazadeh, Manuel Erhard, Feiran Wang +4
Transformations on quantum states form a basic building block of every quantum information system. From photonic polarization to two-level atoms, complete sets of quantum gates for…
