Hearing the light: stray-field noise from the emergent photon in quantum spin ice
Gautam K. Naik, Jonathan N. Hallén, Nishan C. Jayarama +2
Decisive experimental confirmation of the quantum spin liquid phase in quantum spin ice remains an outstanding challenge. In this work, we propose stray-field magnetometry a…
Multi-Qubit Stabilizer Readout on a Dual-Species Rydberg Array
Yu Wang, Ryan Cimmino, Kenneth Wang +7
The ability to locally control and measure subsets of ancilla qubits in an efficient and crosstalk-free manner is a key ingredient in quantum error correction (QEC). Dual-species n…
Theory of Scalable Spin Squeezing with Disordered Quantum Dipoles
Avi Kaplan-Lipkin, Philip J. D. Crowley, Jonathan N. Hallén +6
Spin squeezed entanglement enables metrological precision beyond the classical limit. Understood through the lens of continuous symmetry breaking, dipolar spin systems exhibit the…
Theta electromagnetism in quantum spin ice: Microscopic analysis of improper symmetries
Gautam K. Naik, Jonathan N. Hallén, Chris R. Laumann
gauge theories, including conventional Maxwell electromagnetism, allow -terms when parity and time-reversal symmetry are broken. In condensed matter systems, the physics…
