Quantum Photonic Interconnect

Jianwei Wang, Damien Bonneau, Matteo Villa +12

Integrated photonics has enabled much progress towards quantum technologies. Many applications, including quantum communication, sensing, and distributed and cloud quantum computin…

Theory of the strongly-damped quantum harmonic oscillator

Stephen M. Barnett, James D. Cresser, Sarah Croke

We analyse the properties of a strongly-damped quantum harmonic oscillator by means of an exact diagonalisation of the full Hamiltonian, including both the oscillator and the reser…

Parallel axis theorem for free-space electron wavefunctions

Colin R. Greenshields, Sonja Franke-Arnold, Robert L. Stamps

We consider the orbital angular momentum of a free electron vortex moving in a uniform magnetic field. We identify three contributions to this angular momentum: the canonical orbit…

The information of high-dimensional time-bin encoded photons

Thomas Brougham, Christoph F. Wildfeuer, Stephen M. Barnett +1

We determine the shared information that can be extracted from time-bin entangled photons using frame encoding. We consider photons generated by a general down-conversion source an…

Testing for entanglement with periodic coarse-graining

Daniel S. Tasca, Łukasz Rudnicki, Reuben S. Aspden +3

Continuous variables systems find valuable applications in quantum information processing. To deal with an infinite-dimensional Hilbert space, one in general has to handle large nu…

The Quantum Hilbert Hotel

Václav Potocek, Filippo M. Miatto, Mohammad Mirhosseini +5

In 1924 David Hilbert conceived a paradoxical tale involving a hotel with an infinite number of rooms to illustrate some aspects of the mathematical notion of "infinity". In contin…

Recovering full coherence in a qubit by measuring half of its environment

Filippo M. Miatto, Kevin Piché, Thomas Brougham +1

When quantum systems interact with the environment they lose their quantum properties, such as coherence. Quantum erasure makes it possible to restore coherence in a system by meas…

Nonlinear interferometer for tailoring the frequency spectrum of bright squeezed vacuum

T. Sh. Iskhakov, S. Lemieux, A. Perez +3

We propose a method for tailoring the frequency spectrum of bright squeezed vacuum by generating it in a nonlinear interferometer, consisting of two down-converting nonlinear cryst…
