Variational Joint Magnetometry and Gradiometry on Dipolar Spin Chains
Priyam Srivastava, Xin Jin, Junyu Liu +4
Estimating a uniform magnetic field B0 and its spatial gradient g on a dipolar-coupled spin chain calls for a multiparameter figure of merit. The GHZ state, optimal for single-para…
Four Generations of Quantum Biomedical Sensors
Xin Jin, Priyam Srivastava, Ronghe Wang +7
Quantum sensing technologies offer transformative potential for ultra-sensitive biomedical sensing, yet their clinical translation remains constrained by classical noise limits and…
Achieving Sub-Zeptonewton Force Sensitivity and Spin-Motion Entanglement in Levitated Diamond via Pulsed Backaction Evasion
Gayathrini Premawardhana, Jonathan Beaumariage, M. V. Gurudev Dutt +3
We propose a system to achieve sub-zeptonewton force sensing and robust spin-mechanical entanglement in a levitated diamond system. By coupling a nitrogen-vacancy (NV) center spin…
All-Dielectric Resonant Cavity Electro-Optic Transduction Between Microwave and Telecom
Mihir Khanna, Yang Hu, Thomas P. Purdy
We present a resonant electro-optic transducer for efficient conversion between microwave and telecom wavelength photons. Our platform employs a bulk lithium niobate crystal whose…
Visualizing Detection Efficiency in Optomechanical Scattering
Youssef Tawfik, Shan Hao, Thomas P. Purdy
Many optical measurement techniques, such as light scattering from wavelength-scale particles or detecting motion from a surface with an optical lever, encode information in a comp…
Quartz phononic crystal resonators for hybrid acoustic quantum memories
Yang Hu, Angad Gupta, Jacob Repicky +2
Circuit quantum acoustodynamics systems have emerged as a promising platform for quantum information by coupling superconducting qubits to mechanical resonators, with their long-li…
A Spin-Based Pathway to Testing the Quantum Nature of Gravity
Sougato Bose, Anupam Mazumdar, Roger Penrose +52
A key open problem in physics is the correct way to combine gravity (described by general relativity) with everything else (described by quantum mechanics). This problem suggests t…
Bose-Einstein condensation in a mm-scale Ioffe-Pritchard trap
Kevin L. Moore, Thomas P. Purdy, Kater W. Murch +4
We have constructed a mm-scale Ioffe-Pritchard trap capable of providing axial field curvature of 7800 G/cm with only 10.5 Amperes of driving current. Our novel fabrication met…
