What's New in Quantum
The day's most important quantum-physics stories from six science newsrooms, introduced by Dr. Q and linked to the chapter of the course that explains the physics behind each one.
Dr. Q's Daily Dispatch, Wed, Oct 21
Don't panic — superpose. Then read today's dispatch. Leading today's bulletin, Phys.org reports “A hidden rivalry between two quantum states at the heart of superconductors”. On the next bench, also from Phys.org: “Steering electrons with extreme ultraviolet light—team achieves quantum coherent control”. And a third from the same desk: “Scientists redetermine a key strontium frequency with 50 times better precision for quantum technologies”. Read past the headlines before you believe them: the error bars live in the papers. Science is the only madness with receipts.
Assembled from today's top headlines.

A hidden rivalry between two quantum states at the heart of superconductors
Transmitting electricity without losing any energy may sound impossible, yet this is precisely the promise of superconductivity. For nearly 40 years, scientists have been working to understand materials that exhibit this remarkable property at relatively high temperatures.

Steering electrons with extreme ultraviolet light—team achieves quantum coherent control
Light is one of the most powerful tools scientists have for probing matter. By interacting with electrons, light reveals how atoms, molecules and materials are structured and how they evolve in time.

Scientists redetermine a key strontium frequency with 50 times better precision for quantum technologies
The Korea Research Institute of Standards and Science (KRISS) has remeasured a key transition frequency of the strontium (Sr) atom for the first time in 88 years, since 1938, using a photonic grating chip.

Physicists create a bizarre new quantum state called a fractional fermi sea
Physicists have discovered a strange new state of quantum matter in which ultracold atoms defy familiar organizational rules, forming a highly excited yet surprisingly orderly configuration called a "fractional Fermi sea." The discovery challenges established quantum theories…
