Quantum types: going beyond qubits and quantum gates
Tamás Varga, Yaiza Aragonés-Soria, Manuel Oriol
Quantum computing is a growing field with significant potential applications. Learning how to code quantum programs means understanding how qubits work and learning to use quantum…
Hierarchical certification of nonclassical network correlations
Ming-Xing Luo, Xue Yang, Alejandro Pozas-Kerstjens
With the increased availability of quantum technological devices, it becomes more important to have tools to guarantee their correct nonclassical behavior. This is especially impor…
Quadratic Zeeman Spectral Diffusion of Thulium Ion Population in a Yttrium Gallium Garnet Crystal
Jacob H. Davidson, Antariksha Das, Nir Alfasi +3
The creation of well understood structures using spectral hole burning is an important task in the use of technologies based on rare earth ion doped crystals. We apply a series of…
Long-Range QKD without Trusted Nodes is Not Possible with Current Technology
Bruno Huttner, Romain Alléaume, Eleni Diamanti +11
A recently published patent (https://www.ipo.gov.uk/p-ipsum/Case/PublicationNumber/GB2590064) has claimed the development of a novel quantum key distribution protocol purporting to…
Entanglement swapping and quantum correlations via Elegant Joint Measurements
Cen-Xiao Huang, Xiao-Min Hu, Yu Guo +8
We use hyper-entanglement to experimentally realize deterministic entanglement swapping based on quantum Elegant Joint Measurements. These are joint projections of two qubits onto…
Learning entanglement breakdown as a phase transition by confusion
M. A. Gavreev, A. S. Mastiukova, E. O. Kiktenko +1
Quantum technologies require methods for preparing and manipulating entangled multiparticle states. However, the problem of determining whether a given quantum state is entangled o…
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…
Bilocal Bell inequalities violated by the quantum Elegant Joint Measurement
Armin Tavakoli, Nicolas Gisin, Cyril Branciard
Network Bell experiments give rise to a form of quantum nonlocality that conceptually goes beyond Bell's theorem. We investigate here the simplest network, known as the bilocality…
