Cross-verification of independent quantum devices

C. Greganti, T. F. Demarie, M. Ringbauer +13

Quantum computers are on the brink of surpassing the capabilities of even the most powerful classical computers. This naturally raises the question of how one can trust the results…

Constructing the spin-1 Haldane phase on a qudit quantum processor

C. L. Edmunds, E. Rico, I. Arrazola +4

Symmetry-protected topological phases have fundamentally changed our understanding of quantum matter. An archetypal example of such a quantum phase of matter is the Haldane phase,…

Generation of mechanical interference fringes by multi-photon counting

M. Ringbauer, T. J. Weinhold, L. A. Howard +2

Exploring the quantum behaviour of macroscopic objects provides an intriguing avenue to study the foundations of physics and to develop a suite of quantum-enhanced technologies. On…

Experimental Test of Nonlocal Causality

M. Ringbauer, C. Giarmatzi, R. Chaves +3

Explaining observations in terms of causes and effects is central to all of empirical science. Correlations between entangled quantum particles, however, seem to defy such an expla…

Quantum Hypercube States

L. A. Howard, T. J. Weinhold, F. Shahandeh +4

We introduce quantum hypercube states, a class of continuous-variable quantum states that are generated as orthographic projections of hypercubes onto the quadrature phase-space of…

Challenging local realism with human choices

The BIG Bell Test Collaboration, C. Abellán, A. Acín +105

A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism. A Bell test requires spatially distributed entanglem…
