John Wheeler summarized in a popular science book his path to an informational “world-view”: “I think of my lifetime in physics as divided into three periods. In the first period… I was in the grip of the idea that Everything is Particles… I call my…

A number of no-go theorems suggest that theories upholding both unitarity and relativity must deny that events are absolute.

We are excited to announce a special Birthday Symposium dedicated to celebrating Prof. Daniel Greenberger's remarkable career and contributions to the world of modern quantum physics.

A review of the historical context of Born-Wiener’s contribution to the introduction of operational calculus in quantum mechanics.

A review of Wiener’s paper on operational calculus and the Born-Wiener paper on linear motion.

A distinct protocol for performing a gravitational quantum switch was recently introduced in [N. S. M., B. Sahdo, N. Yokomizo, arXiv:2306.10984], which is the subject of this talk. The quantum switch is the simplest example of a task with indefinite…

In 1998 astronomers discovered that the expansion of the universe is accelerating. Somehow, something must have made gravity repulsive on cosmological scales.

To the best of our knowledge, the Schrodinger equation in quantum mechanics is linear.

We provide a systematic method for nonlinear entanglement detection based on trace polynomial inequalities.

Thanks to its large accessible Hilbert space, using motional states of trapped ions for quantum simulations and quantum computing shows promise. However, such applications require implementing various forms of strong and well controlled nonlinear…
