Phase transitions, like water freezing into ice, are a familiar part of our world. But in quantum systems, they can behave even more dramatically, with quantum properties such as Heisenberg uncertainty playing a central role. Furthermore, various…

Quantum Milestones, 1993: Teleportation Is Not Science Fiction
• Physics 18, 52
Theorists proposed an idea they called quantum teleportation—a means of transferring the identity of one particle to another over some distance.

Experts Weigh in on Microsoft’s Topological Qubit Claim
As MZMs are “topological” states, their settings cannot easily be flipped by random fluctuations to introduce errors into the calculation. Rather, the states are like a twist in a buckled belt that cannot be smoothed out unless the buckle is…

Record Smashing Electron Beam Delivers a Petawatt of Power in an Instant : ScienceAlert
Physicists at SLAC National Accelerator Laboratory in the US have shattered the record for most powerful beam of electrons, cramming an ultra-high current of around 100,000 amps into an instant.
At around five times the field strength of what…

Lab-Created Aurora Highlights New Polymer Physics
• Physics 18, 51
The discovery of a mini aurora above a light-emitting polymer material reveals an electron-ejection process that might be useful in field-emission displays and material fabrication.
Polymer Lights.… Continue Reading

Quantum Milestones, 1964: John Stewart Bell Quietly Rings in New Era of Quantum Theory
• Physics 18, 53
In 1964, Bell showed that quantum physics predicts correlations that violate certain inequalities. The work implied that quantum mechanics is not compatible with locality, even if there were “hidden…

Encapsulation with Noble Metal Improves Superconducting Qubit Performance
• Physics 18, s23
The quantum properties of superconducting qubits might be improved by coating them with a noble metal such as gold.
Superconducting qubits are a leading qubit option for quantum computers. But, as with…

Sneaky clocks: Uncovering Einstein’s relativity in an interacting atomic playground
For over a century, physicists have grappled with one of the most profound questions in science: How do the rules of quantum mechanics, which govern the smallest particles, fit with the laws of general relativity, which describe the universe on…
