Three-Axis Spin Squeezing and Quantum Phase Transitions
Analysis
This paper introduces a novel framework for generating spin-squeezed states, crucial for quantum-enhanced metrology. It extends existing methods by incorporating three-axis squeezing, offering improved tunability and entanglement generation, especially in low-spin systems. The connection to quantum phase transitions and rotor analogies provides a deeper understanding and potential for new applications in quantum technologies.
Key Takeaways

- •Connects spin squeezing with quantum phase transitions.
- •Suggests applications in Rydberg arrays and cavity-QED platforms.
Reference
“The three-axis framework reproduces the known N^(-2/3) scaling of one-axis twisting and the Heisenberg-limited N^(-1) scaling of two-axis twisting, while allowing additional tunability and enhanced entanglement generation in low-spin systems.”
