Quantum-enhanced accelerometry with a non-linear electromechanical circuit
Kurt Jacobs, Radhakrishnan Balu, John D. Teufel
It is known that placing a mechanical oscillator in a superposition of coherent states allows, in theory, a measurement of a linear force whose sensitivity increases with the ampli…
Continuous-time limit of topological quantum walks
Radhakrishnan Balu, Daniel Castillo, George Siopsis +1
We derive the continuous-time limit of discrete quantum walks with topological phases. We show the existence of a continuous-time limit that preserves their topological phases. We…
Steady states of continuous-time open quantum walks
Chaobin Liu, Radhakrishnan Balu
Continuous-time open quantum walks (CTOQW) are introduced as the formulation of quantum dynamical semigroups of trace-preserving and completely positive linear maps (or quantum Mar…
All-mechanical quantum noise cancellation for accelerometry: broadband with momentum measurements, narrow band without
Kurt Jacobs, Nikolas Tezak, Hideo Mabuchi +1
We show that the ability to make direct measurements of momentum, in addition to the usual direct measurements of position, allows a simple configuration of two identical mechanica…
Exponential capacity of associative memories under quantum annealing recall
Siddhartha Santra, Omar Shehab, Radhakrishnan Balu
Associative memory models, in theoretical neuro- and computer sciences, can generally store a sublinear number of memories. We show that using quantum annealing for recall tasks en…
