The PLATO Mission
Heike Rauer, Conny Aerts, Juan Cabrera +842
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…
Near-resonant optical forces beyond the two-level approximation for a continuous source of spin-polarized cold atoms
Thomas Vanderbruggen, Morgan Mitchell
We propose a method to generate a source of spin-polarized cold atoms which are continuously extracted and guided from a magneto-optical trap using an atom-diode effect. We show th…
Simple proof of equivalence between adiabatic quantum computation and the circuit model
Ari Mizel, Daniel A. Lidar, Morgan Mitchell
We prove the equivalence between adiabatic quantum computation and quantum computation in the circuit model. An explicit adiabatic computation procedure is given that generates a g…
Multiparameter quantum sensing and magnetic communications with a hybrid dc and rf optically pumped magnetometer
MichaÅ Lipka, Aleksandra Sierant, Charikleia Troullinou +1
We introduce and demonstrate a hybrid optically pumped magnetometer (HOPM) that simultaneously measures one dc field component and one rf field component quadrature with a single a…
Fast-field-cycling, ultralow-field nuclear magnetic relaxation dispersion
Sven Bodenstedt, Morgan Mitchell, Michael Tayler
Optically pumped magnetometers (OPMs) based on alkali-atom vapors are ultra-sensitive devices for dc and low-frequency ac magnetic measurements. Here, in combination with fast-fiel…
Randomness in Quantum Mechanics: Philosophy, Physics and Technology
Manabendra Nath Bera, Antonio AcÃn, Marek KuÅ +2
This progress report covers recent developments in the area of quantum randomness, which is an extraordinarily interdisciplinary area that belongs not only to physics, but also to…
Quantum non-demolition measurement enables macroscopic Leggett-Garg tests
Costantino Budroni, Giuseppe Vitagliano, Giorgio Colangelo +4
We show how a test of macroscopic realism based on Leggett-Garg inequalities (LGIs) can be performed in a macroscopic system. Using a continuous-variable approach, we consider quan…
Spontaneous PT symmetry breaking of a ferromagnetic superfluid in a gradient field
Thomas Vanderbruggen, Silvana Palacios, Simon Coop +2
We consider the interaction of a ferromagnetic spinor Bose-Einstein condensate with a magnetic field gradient. The magnetic field gradient realizes a spin-position coupling that ex…
