Hardware-efficient quantum error correction via concatenated bosonic qubits
Harald Putterman, Kyungjoo Noh, Connor T. Hann +118
In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many…
Nonlinearity in nanomechanical cantilevers
L. G. Villanueva, R. B. Karabalin, M. H. Matheny +3
Euler-Bernoulli beam theory is widely used to successfully predict the linear dynamics of micro- and nano-cantilever beams. However, its capacity to characterize the nonlinear dyna…
Optimal operating points of oscillators using nonlinear resonators
Eyal Kenig, M. C. Cross, L. G. Villanueva +4
We demonstrate an analytical method for calculating the phase sensitivity of a class of oscillators whose phase does not affect the time evolution of the other dynamic variables. W…
Stress-Induced Variations in the Stiffness of Micro- and Nanocantilever Beams
Rassul B. Karabalin, L. G. Villanueva, M. H. Matheny +2
The effect of surface stress on the stiffness of cantilever beams remains an outstanding problem in the physical sciences. While numerous experimental studies report significant st…
A Nanoscale Parametric Feedback Oscillator
L. Guillermo Villanueva, Rassul B. Karabalin, Matthew H. Matheny +3
We describe and demonstrate a new oscillator topology, the parametric feedback oscillator (PFO). The PFO paradigm is applicable to a wide variety of nanoscale devices, and opens th…
Surpassing fundamental limits of oscillators using nonlinear resonators
L. G. Villanueva, E. Kenig, R. B. Karabalin +4
Self-sustained oscillators are ubiquitous and essential for metrology, communications, time reference, and geolocation. In its most basic form an oscillator consists of a resonator…
