Quantum State Characterization of Gravitational Waves via Graviton Counting Statistics

Kristian Toccacelo, Thomas Beitel, Ulrik Lund Andersen +1

Although gravitational waves are now routinely observed, the detection of individual gravitons has long been regarded as impossible. Recent work, however, has demonstrated that sin…

A One-sided Witness for the Quantumness of Gravitational Dynamics

Konstantin Beyer, M. S. Kim, Igor Pikovski

Quantum information concepts and quantum technologies have opened the prospect to probe quantum gravity in table-top experiments. Many proposals rely on witnessing entanglement gen…

Testing quantum theory on curved space-time with quantum networks

Johannes Borregaard, Igor Pikovski

Quantum technologies present new opportunities for fundamental tests of nature. One potential application is to probe the interplay between quantum physics and general relativity -…

Probing classical and quantum violations of the equivalence of active and passive gravitational mass

Vasileios Fragkos, Igor Pikovski

The equivalence of active and passive (EAP) gravitational mass is one of the most fundamental principles of gravity. But in contrast to the usual equivalence of inertial and (passi…

A coupling prescription for post-Newtonian corrections in Quantum Mechanics

Jelle Hartong, Emil Have, Niels A. Obers +1

The interplay between quantum theory and general relativity remains one of the main challenges of modern physics. A renewed interest in the low-energy limit is driven by the prospe…

Detecting single gravitons with quantum sensing

Germain Tobar, Sreenath K. Manikandan, Thomas Beitel +1

The quantization of gravity is widely believed to result in gravitons -- particles of discrete energy that form gravitational waves. But their detection has so far been considered…
