Quantum network tomography of Rydberg arrays by machine learning
Kaustav Mukherjee, Johannes Schachenmayer, Shannon Whitlock +1
Configurable arrays of optically trapped Rydberg atoms are a versatile platform for quantum computation and quantum simulation, also allowing controllable decoherence. We demonstra…
Spontaneous Torque on an Inhomogeneous Chiral Body out of Thermal Equilibrium
Kimball A. Milton, Nima Pourtolami, Gerard Kennedy
In a previous paper we showed that an inhomogeneous body in vacuum will experience a spontaneous force if it is not in thermal equilibrium with its environment. This is due to the…
Efficient quantum algorithm for weighted partial sums and numerical integration
Alok Shukla, Prakash Vedula
This paper presents a quantum algorithm for efficiently computing partial sums and specific weighted partial sums of quantum state amplitudes. Computation of partial sums has impor…
Characterizing the transition from topology to chaos in a kicked quantum system
J. Mumford, H. -Y. Xie, R. J. Lewis-Swan
This work theoretically investigates the transition from topology to chaos in a periodically driven system consisting of a quantum top coupled to a spin-1/2 particle. The system is…
Topologically protected Bell-cat states in a simple spin model
B. Lajci, D. H. J. O'Dell, J. Mumford
We consider the topological properties of the so-called central spin model that consists of identical spins coupled to a single distinguishable central spin which arises in phy…
Dynamical Structure Factor from Weak Measurements
E. Altuntas, R. G. Lena, S. Flannigan +2
Much of our knowledge of quantum systems is encapsulated in the expectation value of Hermitian operators, experimentally obtained by averaging projective measurements. However, dyn…
Variational quantum state preparation for quantum-enhanced metrology in noisy systems
Juan C. Zuñiga Castro, Jeffrey Larson, Sri Hari Krishna Narayanan +3
We investigate optimized quantum state preparation for quantum metrology applications in noisy environments. Using the QFI-Opt package, we simulate a low-depth variational quantum…
A quantum approach for optimal control
Hirmay Sandesara, Alok Shukla, Prakash Vedula
In this work, we propose a novel variational quantum approach for solving a class of nonlinear optimal control problems. Our approach integrates Dirac's canonical quantization of d…
Challenges with Differentiable Quantum Dynamics
Sri Hari Krishna Narayanan, Michael Perlin, Robert Lewis-Swan +4
Differentiable quantum dynamics require automatic differentiation of a complex-valued initial value problem, which numerically integrates a system of ordinary differential equation…
Quantum Self-Propulsion of an Inhomogeneous Object out of Thermal Equilibrium
Kimball A. Milton, Nima Pourtolami, Gerard Kennedy
In an earlier paper, we explored how quantum vacuum torque can arise: a body or nanoparticle that is out of thermal equilibrium with its environment experiences a spontaneous torqu…
Hybrid classical-quantum image processing via polar Walsh basis functions
Mohit Rohida, Alok Shukla, Prakash Vedula
We propose a novel hybrid classical-quantum approach for image processing based on polar Walsh basis functions. Using this approach, we present an algorithm for the removal of the…
