Spin-bounded correlations: rotation boxes within and beyond quantum theory
Albert Aloy, Thomas D. Galley, Caroline L. Jones +2
How can detector click probabilities respond to spatial rotations around a fixed axis, in any possible physical theory? Here, we give a thorough mathematical analysis of this quest…
A general approach to backaction-evading receivers with magnetomechanical and electromechanical sensors
Brittany Richman, Sohitri Ghosh, Daniel Carney +4
Today's mechanical sensors are capable of detecting extremely weak perturbations while operating near the standard quantum limit. However, further improvements can be made in both…
Quantum control of continuous systems via nonharmonic potential modulation
Piotr T. Grochowski, Hannes Pichler, Cindy A. Regal +1
We present a theoretical proposal for preparing and manipulating a state of a single continuous-variable degree of freedom confined to a nonharmonic potential. By utilizing optimal…
Quantum Coding with Finite Thermodynamic Resources
Jake Xuereb, Tiago Debarba, Marcus Huber +1
Quantum direct coding or Schumacher compression generalised the ideas of Shannon theory, gave an operational meaning to the von Neumann entropy and established the term qubit. But…
Variational manifolds for ground states and scarred dynamics of blockade-constrained spin models on two and three dimensional lattices
Joey Li, Giuliano Giudici, Hannes Pichler
We introduce a variational manifold of simple tensor network states for the study of a family of constrained models that describe spin-1/2 systems as realized by Rydberg atom array…
Many-body entropies and entanglement from polynomially-many local measurements
Benoît Vermersch, Marko Ljubotina, J. Ignacio Cirac +3
Estimating global properties of many-body quantum systems such as entropy or bipartite entanglement is a notoriously difficult task, typically requiring a number of measurements or…
Coherent spin-phonon scattering in facilitated Rydberg lattices
Matteo Magoni, Chris Nill, Igor Lesanovsky
We investigate the dynamics of a spin system with facilitation constraint that can be studied using Rydberg atoms in arrays of optical tweezer traps. The elementary degrees of free…
Experimental Observation of Earth's Rotation with Quantum Entanglement
Raffaele Silvestri, Haocun Yu, Teodor Stromberg +3
Precision interferometry with quantum states has emerged as an essential tool for experimentally answering fundamental questions in physics. Optical quantum interferometers are of…
State independent QKD
Robert Kindler, Johannes Handsteiner, Jaroslav Kysela +3
We present an adaptive procedure for aligning quantum non-locality experiments without any knowledge of the two-qudit state shared by the participating parties. The quantum state p…
Simulating 2D lattice gauge theories on a qudit quantum computer
Michael Meth, Jan F. Haase, Jinglei Zhang +11
Particle physics underpins our understanding of the world at a fundamental level by describing the interplay of matter and forces through gauge theories. Yet, despite their unmatch…
Genuine multipartite entanglement detection with imperfect measurements: concept and experiment
Huan Cao, Simon Morelli, Lee A. Rozema +3
Standard procedures for entanglement detection assume that experimenters can exactly implement specific quantum measurements. Here, we depart from such idealizations and investigat…
Gravity Mediated Entanglement between Oscillators as Quantum Superposition of Geometries
Ofek Bengyat, Andrea Di Biagio, Markus Aspelmeyer +1
Protocols for observing gravity induced entanglement typically comprise the interaction of two particles prepared either in a superposition of two discrete paths, or in a continuou…
On The Stabilizer Formalism And Its Generalization
Éloi Descamps, Borivoje Dakić
The standard stabilizer formalism provides a setting to show that quantum computation restricted to operations within the Clifford group are classically efficiently simulable: this…
Quantum Superpositions of Conscious States in a Minimal Integrated Information Model
Kelvin J. McQueen, Ian T. Durham, Markus P. Mueller
Could there be quantum superpositions of conscious states, as suggested by the Wigner's friend thought experiment? Mathematical theories of consciousness, notably Integrated Inform…
Relating Wigner's Friend Scenarios to Nonclassical Causal Compatibility, Monogamy Relations, and Fine Tuning
Yìlè Yīng, Marina Maciel Ansanelli, Andrea Di Biagio +3
Nonclassical causal modeling was developed in order to explain violations of Bell inequalities while adhering to relativistic causal structure and faithfulness -- that is, avoiding…
Macroscopic quantum entanglement between an optomechanical cavity and a continuous field in presence of non-Markovian noise
Su Direkci, Klemens Winkler, Corentin Gut +3
Probing quantum entanglement with macroscopic objects allows us to test quantum mechanics in new regimes. One way to realize such behavior is to couple a macroscopic mechanical osc…
Compatibility of Generalized Noisy Qubit Measurements
Martin J. Renner
It is a crucial feature of quantum mechanics that not all measurements are compatible with each other. However, if measurements suffer from noise they may lose their incompatibilit…
Response to "The measurement postulates of quantum mechanics are not redundant"
Lluís Masanes, Thomas D. Galley, Markus P. Müller
Adrian Kent has recently presented a critique [arXiv:2307.06191] of our paper [Nat. Comms. 10, 1361 (2019)] in which he claims to refute our main result: the measurement postulates…
Measurement events relative to temporal quantum reference frames
Ladina Hausmann, Alexander Schmidhuber, Esteban Castro-Ruiz
The Page-Wootters formalism is a proposal for reconciling the background-dependent, quantum-mechanical notion of time with the background independence of general relativity. Howeve…
