Nondestructive interaction-free atom-photon controlled-NOT gate

, 2007
We present a probabilistic (ideally 50%) nondestructive interaction-free atom-photon controlled-NOT gate, where nondestructive means that all four outgoing target photon modes of the gate are available and feed-forwardable.

Space-Efficient Straggler Identification in Round-Trip Data Streams Via Newton’s Identities and Invertible Bloom Filters [PDF]

, 2007
We study the straggler identification problem, in which an algorithm must determine the identities of the remaining members of a set after it has had a large number of insertion and deletion operations performed on it, and now has relatively few remaining members.

Analysis of Round-Trip Efficiency of an HVAC-Based Virtual Battery

, 2018
The flexibility in power consumption of heating, ventilation, and air-conditioning (HVAC) systems in buildings can be utilized to provide a battery-like service to the power grid. Recent work has reported that using HVAC systems in such a manner may lead to a net increase in energy consumption compared to normal operation, similar to a low round-trip ...
