Testing real quantum theory in an optical quantum network

Zheng-Da Li, Ya-Li Mao, Mirjam Weilenmann +12

Quantum theory is commonly formulated in complex Hilbert spaces. However, the question of whether complex numbers need to be given a fundamental role in the theory has been debated…

Measurement of the Thulium Ion Spin Hamiltonian Within a Yttrium Gallium Garnet Host Crystal

Jacob H. Davidson, Philip J. T. Woodburn, Aaron D. Marsh +7

We characterize the magnetic properties for thulium ion energy levels in the YGaO (Tm:YGG) lattice with the goal to improve decoherence and reduce line-width broaden…

A long-lived solid-state optical quantum memory for high-rate quantum repeaters

Mohsen Falamarzi Askarani, Antariksha Das, Jacob H. Davidson +8

We argue that long optical storage times are required to establish entanglement at high rates over large distances using memory-based quantum repeaters. Triggered by this conclusio…

Non-Local Boxes for Networks

Jean-Daniel Bancal, Nicolas Gisin

Nonlocal boxes are conceptual tools that capture the essence of the phenomenon of quantum non-locality, central to modern quantum theory and quantum technologies. We introduce netw…

The relativity of indeterminacy

Flavio Del Santo, Nicolas Gisin

A long-standing tradition, largely present in both the physical and the philosophical literature, regards the advent of (special) relativity -- with its block-universe picture -- a…
