Three-angle precession protocols and the classical inequality
Tsirelson’s precession protocol and its generalisations involve uniformly precessing observables. A pair of observables Ax(θ) and Ay(θ) with a parametric dependence on θ are…

Scientist Connected Light And Matter Century Before Quantum Physics : ScienceAlert
The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin’s Broome Bridge in 1843.
But in his lifetime, Hamilton’s reputation rested on…

The phantom heat of empty space might soon be detectable
Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect — a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their novel approach opens new possibilities for…

Detecting the purely imaginary Fisher zeros of an Ising spin system on a quantum computer
In this section, we apply our protocol to calculate the purely imaginary Fisher zeros of certain Ising models on the ibm-lagos quantum computer. The ibm-lagos quantum device is composed of seven superconducting qubits that interact with each…
