High-order tensor flow processing using integrated photonic circuits

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Shaofu Xu, Jing Wang, Sicheng Yi, Weiwen Zou, | Summary: Tensor analytics lays mathematical basis for the prosperous promotion of multiway signal processing. To increase computing throughput, mainstream processors transform tensor convolutions to matrix multiplications to enhance parallelism of computing. However, such order-reducing transformation produces data duplicates […]

Asteroids for microhertz gravitational-wave detection

Posted by klaurent Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Surjeet Rajendran, , | Summary: A major challenge for gravitational-wave (GW) detection in the $mu$Hz band is engineering a test mass (TM) with sufficiently low acceleration noise. We propose a GW detection concept using asteroids located in the inner Solar […]

Gravitationally Mediated Entanglement: Newtonian Field vs. Gravitons

Posted by Chicago

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, , | Summary: We argue that if the Newtonian gravitational field of a body can mediate entanglement with another body, then it should also be possible for the body producing the Newtonian field to entangle directly with on-shell […]
