Boosting the Performance of Quantum Repeaters 

Multiplexing techniques could boost the chances of achieving end-to-end entanglement of a signal in a trapped-ion-based quantum-computer network - Erika K. Carlson - APS Physics - February 2022

 

No, putting a spoon in an open bottle of champagne doesn't keep it bubbly, but there is a better way 

... The fact is, it's a myth to say a spoon in an open bottle of sparkling wine keeps it bubbly. You're better off buying a proper stopper - Geoff Scollary, The Conversation - Phys-Org - January 2022

 

Dune auroras shine light on atmospheric dynamics 

Their alternating pattern likely indicates a connection with waves in the upper mesosphere - Christine Middleton - Physics Today - May 24th 2021.

 

Quantum-entangled drones share secure messages 

Researchers transmitted photonic qubits through free space using a cost-effective, mobile network of nodes - Zhenda Xie, Yan-Xiao Gong, and Shi-Ning Zhu of Nanjing University in China have accelerated an alternative approach - Alex Lopatka - Physics Today - February 19th 2021.

 

Finding New Forces with Old Techniques 

Interactions predicted by beyond-standard-model theories could be detected using a variation on Mössbauer spectroscopy, according to a new proposal. - Marric Stephens - APS Physics - December 24th 2020.

 

Nobel Prize: Facing the Reality of Black Holes Three scientists were recognized for proving that gravitational collapse can lead to a black hole and for observing the supermassive black hole at the center of our Galaxy - Michael Schirber - APS News - October 2020

 

A Few Qubits Go a Long Way  The right combination of quantum and classical computations allows for accurate quantum chemistry simulations using surprisingly few qubits - Marric Stephens - APS News - January 2020

 

Directly Measuring an Entangled State Researchers have directly measured the components of a nonlocal, entangled wave function, rather than relying on indirect tomographic or reconstructive techniques - David Starling - APS News - October 2019
