Correlating the nanostructure of Al-oxide with deposition conditions and dielectric contributions of two-level systems in perspective of superconducting quantum circuits
S. Fritz, A. Seiler, L. Radtke +4
This work is concerned with Al/Al-oxide(AlO)/Al-layer systems which are important for Josephson-junction-based superconducting devices such as quantum bits. The device perfor…
Silicon photonic processor of two-qubit entangling quantum logic
R. Santagati, J. W. Silverstone, M. J. Strain +11
Entanglement is a fundamental property of quantum mechanics, and is a primary resource in quantum information systems. Its manipulation remains a central challenge in the developme…
Vacuum Friction
Stephen M. Barnett, Matthias Sonnleitner
We know that in empty space there is no preferred state of rest. This is true both in special relativity but also in Newtonian mechanics with its associated Galilean relativity. It…
Coherent metamaterial absorption of two-photon states with 40% efficiency
Ashley Lyons, Dikla Oren, Thomas Roger +6
Multi-photon absorption processes have a nonlinear dependence on the amplitude of the incident optical field i.e. the number of photons. However, multi-photon absorption is general…
Attosecond-Resolution Hong-Ou-Mandel Interferometry
Ashley Lyons, George C. Knee, Eliot Bolduc +4
When two indistinguishable photons are each incident on separate input ports of a beamsplitter they `bunch' deterministically, exiting via the same port as a direct consequence of…
Experimental study of quantum thermodynamics using optical vortices
R. Medeiros de Araújo, T. Häffner, R. Bernardi +6
Non-equilibrium thermodynamics and quantum information theory are interrelated research fields witnessing an increasing interest, both theoretical and experimental. This is manly d…
Sequential measurements: Busch-Gleason theorem and its applications
Kieran Flatt, Stephen M. Barnett, Sarah Croke
Probabilities enter quantum mechanics via Born's rule, the uniqueness of which was proven by Gleason. Busch subsequently relaxed the assumptions of this proof, expanding its domain…
Optimal sequential measurements for bi-partite state discrimination
Sarah Croke, Stephen M. Barnett, Graeme Weir
State discrimination is a useful test problem with which to clarify the power and limitations of different classes of measurement. We consider the problem of discriminating between…
Optimal discrimination of single-qubit mixed states
Graeme Weir, Stephen M. Barnett, Sarah Croke
We consider the problem of minimum-error quantum state discrimination for single-qubit mixed states. We present a method which uses the Helstrom conditions constructively and analy…
Polarization-entangled photon pair sources based on spontaneous four wave mixing assisted by polarization mode dispersion
Pisek Kultavewuti, Eric Y. Zhu, Xingxing Xing +4
Photonic-based qubits and integrated photonic circuits have enabled demonstrations of quantum information processing (QIP) that promises to transform the way in which we compute an…
Proposed optical realisation of a two photon, four-qubit entangled state
Atirach Ritboon, Sarah Croke, Stephen M. Barnett
The four-qubit states , exhibiting genuinely multi-partite entanglement have been shown to have many interesting properties and have been suggested for novel a…
Space QUEST mission proposal: Experimentally testing decoherence due to gravity
Siddarth Koduru Joshi, Jacques Pienaar, Timothy C. Ralph +42
Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum properties, such as entanglement, may exhi…
Nonuniform currents and spins of relativistic electron vortices in a magnetic field
Koen van Kruining, Armen G. Hayrapetyan, Jörg B. Götte
We present a relativistic description of electron vortex beams in a homogeneous magnetic field. Including spin from the beginning reveals that spin-polarized electron vortex beams…
Nondestructive Measurement of Orbital Angular Momentum for an Electron Beam
Hugo Larocque, Frédéric Bouchard, Vincenzo Grillo +6
Free electrons with a helical phase front, referred to as "twisted" electrons, possess an orbital angular momentum (OAM) and, hence, a quantized magnetic dipole moment along their…
Difficulty of distinguishing product states locally
Sarah Croke, Stephen M Barnett
Non-locality without entanglement is a rather counter-intuitive phenomenon in which information may be encoded entirely in product (unentangled) states of composite quantum systems…
