A ten-qubit solid-state spin register with remarkable quantum memory
In years to come, quantum computers and quantum networks might be able to tackle tasks that are inaccessible to traditional computer systems. For instance, they could be used to simulate complex...
A theoretical explanation for an enhanced thermal Hall response in high-temperature superconductors
A few months ago, a team of researchers led by Louis Taillefer at the University of Sherbrooke measured the thermal Hall conductivity in several compounds of copper, oxygen and other elements that...
A unifying approach for controlling flying robotic insects
One of the key problems confronting researchers in the field of microrobotics is designing and implementing reliable controllers for insect-scale micro air vehicles (FWMAVs), which are tiny flying...
A user-friendly approach for active reward learning in robots
In recent years, researchers have been trying to develop methods that enable robots to learn new skills. One option is for a robot to learn these new skills from humans, asking questions whenever it...
A window for trap-free charge transport in organic semiconductors
Organic semiconductors, a class of carbon-based materials with optical and electronic properties, are now commonly used to fabricate a variety of devices, including solar cells, light-emitting...
Batteries with fluorinated electrolytes that work at very high and low temperatures
Electrolytes are chemical components that enable the flow of ions between the cathode and anode inside batteries, ultimately providing electrical power to technological devices. Most conventional...
Box of Pain: A new tracer and fault injector for distributed systems
In computer science, distributed systems are systems with components located on different devices, which communicate with one another. While these systems have become increasingly common, they are...
Building 3-D models of unknown objects as they are manipulated by robots
Researchers at Rutgers University have recently developed a probabilistic approach for building 3-D models of unknown objects while they are being manipulated by a robot. Their approach, outlined in...
Circular all-or-nothing: A new approach to protect data from key exposure
A team of researchers at Telecom ParisTech has developed a new method to protect encrypted data against key exposure. Their algorithm, presented in a paper pre-published on arXiv, transforms,...
Coupling qubits to sound in a multimode cavity
In a recent study, researchers at the University of Colorado have resolved phonon Fock states in the spectrum of a superconducting qubit coupled to a multimode acoustic cavity. Fock states (or...
