Gun ownership and homicide in the US: A stronger correlation

In 2017, there were nearly 40,000 gun-related deaths in the United States, including homicides and suicides. To delve into this alarming statistic, U.S.-trained Université de Montréal economist Karim Chalak and his coauthors ...

Going gentle on mechanical quantum systems

When thinking about quantum mechanical systems, single photons and well-isolated ions and atoms may spring to mind, or electrons spreading through a crystal. More exotic in the context of quantum mechanics are genuinely mechanical ...

Fault-tolerant quantum computer memory in diamond

Quantum computing holds the potential to be a game-changing future technology in fields ranging from chemistry to cryptography to finance to pharmaceuticals. Compared to conventional computers, scientists suggest that quantum ...

Team simulates collider physics on quantum computer

Lawrence Berkeley National Laboratory physicists Christian Bauer, Marat Freytsis and Benjamin Nachman have leveraged an IBM Q quantum computer through the Oak Ridge Leadership Computing Facility's Quantum Computing User Program ...

Rats can estimate their timing accuracy

Thanks to their capacity for introspection, human beings are able to estimate the duration of their actions. When they perform a task—especially a time-based task—they can evaluate their performance and correct themselves ...

Quantum errors made more tolerable

ETH physicists have modified one of the major schemes for quantum error correction and put it into practice, demonstrating that they can substantially prolong the lifetime of quantum states—a crucial ingredient for future ...
