Two atoms, three spacetimes: when cosmic expansion, acceleration and heat tell the same story
A new theoretical study shows that a single atom cannot distinguish de Sitter expansion, uniform acceleration, and a thermal bath ...

Quantum Entanglement Can Stabilize a Game Strategy, but Only If You Count Strategies Carefully
A new analysis shows entanglement makes a quantum coordination strategy evolutionarily stable only under a restricted strategy space and an ...
Asymmetric Coupling Splits Localized Modes in Photonic Crystal Emitters
Asymmetric optical coupling in a photonic crystal displaces two localized modes, suppressing entanglement revivals while revealing that reservoir memory and ...
Tenerife study benchmarks sea turtle rehabilitation outcomes
A 43-year retrospective study of 2,270 sea turtles in Tenerife found an 86% release rate and cause-specific benchmarks for evaluating ...
Discord, not entanglement, emerges as the key resource behind quantum illumination’s advantage
Quantum illumination is one of the most counterintuitive success stories in quantum information science. In its canonical form, a pair ...
How Migrating Birds May See Earth’s Magnetic Field: A Quantum Guide to the Avian Compass
A new Frontiers in Photonics review uses the quantum radical pair mechanism behind birds' magnetic compass to teach the quantum ...
Quantum radar survives a plasma sheath, until re-entry blackout kills the advantage
An exact quantum Chernoff-bound analysis shows quantum illumination retains a roughly 3-decibel advantage over classical radar through a hypersonic plasma ...
Quantum Teleportation Goes Both Ways: Asymmetric Spin Channels Meet DRAG Pulse Control
Physicists show that a Dzyaloshinskii–Moriya interaction makes two-way quantum teleportation directionally asymmetric, but optimized DRAG pulses can protect the fragile ...
Intrinsic Decoherence Reshapes Quantum Correlations in Hybrid Qubit-Qutrit Spin Chains
A new theoretical study shows how intrinsic decoherence and inhomogeneous magnetic fields jointly control entanglement, quantum discord and metrological precision ...
Quantum Circuit Boosts Small Object Detection to Record Precision
A hybrid quantum-classical detector called Q-SODA uses an eight-qubit entangling circuit to achieve record precision on small object detection while ...
