Quantum emulation of the transient dynamics in the multistate Landau-Zener model
Alexander Stehli, Jan David Brehm, Tim Wolz +4
Quantum simulation is one of the most promising near term applications of quantum computing. Especially, systems with a large Hilbert space are hard to solve for classical computer…
Gravitational decoherence by the apparatus in the quantum-gravity induced entanglement of masses
Fabian Gunnink, Anupam Mazumdar, Martine Schut +1
One of the outstanding questions in modern physics is how to test whether gravity is classical or quantum in a laboratory. Recently there has been a proposal to test the quantum na…
Controlling Photon Entanglement with Mechanical Rotation
Marion Cromb, Sara Restuccia, Graham M. Gibson +3
Understanding quantum mechanics within curved spacetime is a key stepping stone towards understanding the nature of spacetime itself. Whilst various theoretical models have been de…
Shape optimizations for body-assisted light-matter interactions
Jonas Matuszak, Stefan Yoshi Buhmann, Robert Bennett
We implement a shape optimization algorithm for body-assisted light-matter interactions described by the formalism of macroscopic quantum electrodynamics. The approach uses the lev…
Mitigating Source and Detection Noises in Auto-correlative Weak-Value Amplification
Xiang-Yun Hu, Jing-Hui Huang, Fei-Fan He +2
Weak-value amplification (WVA) is a post-selection-based technique that amplifies weak physical signals by preparing nearly orthogonal pre- and post-selected quantum states. It is…
Electro-Optical Sampling of Single-Cycle THz Fields with Single-Photon Detectors
Taylor Shields, Adetunmise C. Dada, Lennart Hirsch +6
Electro-optical sampling of Terahertz fields with ultrashort pulsed probes is a well-established approach for directly measuring the electric field of THz radiation. This technique…
On single-photon and classical interference
Stephen M. Barnett
It has often been remarked that single-photon interference experiments, however complicated, seem to behave very much in the same way as those performed in the classical regime, us…
Multi-partite subspaces containing no locally inaccessible information
Sarah Croke
One notion of non-locality in quantum theory is the fact that information may be encoded in a composite system in such a way that it is not accessible through local measurements, e…
Generation of entanglement from mechanical rotation
Marko Toroš, Marion Cromb, Mauro Paternostro +1
Many phenomena and fundamental predictions, ranging from Hawking radiation to the early evolution of the Universe rely on the interplay between quantum mechanics and gravity or mor…
Numerical studies of back-reaction effects in an analog model of cosmological pre-heating
Salvatore Butera, Iacopo Carusotto
We theoretically propose an atomic Bose-Einstein condensate as an analog model of back-reaction effects during the pre-heating stage of early Universe. In particular, we address th…
Simultaneous cooling of all six degrees of freedom of an optically levitated nanoparticle by elliptic coherent scattering
Antonio Pontin, Hayden Fu, Marko Toroš +2
We report on strong cooling and orientational control of all translational and angular degrees of freedom of a nanoparticle levitated in an optical trap in high vacuum. The motiona…
Requirements on Quantum Superpositions of Macro-Objects for Sensing Neutrinos
Eva Kilian, Marko Toroš, Frank F. Deppisch +2
We examine a macroscopic system in a quantum superposition of two spatially separated localized states as a detector for a stream of weakly interacting relativistic particles. We d…
Auto-correlative weak-value amplification under strong noise background
Jing-Hui Huang, Xiang-Yun Hu, Adetunmise C. Dada +4
By choosing more orthogonality between pre-selection and post-selection states, one can significantly improve the sensitivity in the general optical quantum metrology based on the…
Measurement disturbance tradeoffs in three-qubit unsupervised quantum classification
Hector Spencer-Wood, Sarah Croke, John Jeffers
We consider measurement disturbance tradeoffs in quantum machine learning protocols which seek to learn about quantum data. We study the simplest example of a binary classification…
