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…
QBism: Quantum Theory as a Hero's Handbook
Christopher A. Fuchs, Blake C. Stacey
This paper represents an elaboration of the lectures delivered by one of us (CAF) during "Course 197 -- Foundations of Quantum Physics" at the International School of Physics "Enri…
Nonlinear quantum metrology of many-body open systems
Mathieu Beau, Adolfo del Campo
We introduce general bounds for the parameter estimation error in nonlinear quantum metrology of many-body open systems in the Markovian limit. Given a -body Hamiltonian and …
Universal Work Fluctuations during Shortcuts To Adiabaticity by Counterdiabatic Driving
Ken Funo, Jing-Ning Zhang, Cyril Chatou +3
Counterdiabatic driving (CD) exploits auxiliary control fields to tailor the nonequilibrium dynamics of a quantum system, making possible the suppression of dissipated work in fini…
Observing quantum chaos with noisy measurements and highly mixed states
Jason F. Ralph, Kurt Jacobs, Mark J. Everitt
A fundamental requirement for the emergence of classical behavior from an underlying quantum description is that certain observed quantum systems make a transition to chaotic dynam…
High-Threshold Low-Overhead Fault-Tolerant Classical Computation and the Replacement of Measurements with Unitary Quantum Gates
Benjamin Cruikshank, Kurt Jacobs
Von Neumann's classic "multiplexing" method is unique in achieving high-threshold fault-tolerant classical computation (FTCC), but has several significant barriers to implementatio…
Quantum Simulation of Generic Many-Body Open System Dynamics Using Classical Noise
Aurélia Chenu, Mathieu Beau, Jianshu Cao +1
We introduce a scheme for the quantum simulation of many-body decoherence based on the unitary evolution of a stochastic Hamiltonian. Modulating the strength of the interactions wi…
Digital Quantum Simulation of Minimal AdS/CFT
L. García-Álvarez, I. L. Egusquiza, L. Lamata +3
We propose the digital quantum simulation of a minimal AdS/CFT model in controllable quantum platforms. We consider the Sachdev-Ye-Kitaev model describing interacting Majorana ferm…
Coupling rotational and translational motion via a continuous measurement in an optomechanical sphere
Jason F. Ralph, Kurt Jacobs, Jonathon Coleman
We consider a measurement of the position of a spot painted on the surface of a trapped nano-optomechanical sphere. The measurement extracts information about the position of the s…
Coherent vs. measurement-based feedback for controlling a single qubit
Ashkan Balouchi, Kurt Jacobs
We compare the performance of continuous coherent feedback, implemented using an ideal single-qubit controller, to that of continuous measurement-based feedback for the task of con…
Inhomogeneous quasi-adiabatic driving of quantum critical dynamics in weakly disordered spin chains
Marek M. Rams, Masoud Mohseni, Adolfo del Campo
We introduce an inhomogeneous protocol to drive a weakly disordered quantum spin chain quasi-adiabatically across a quantum phase transition and minimize the residual energy of the…
Truncated Calogero-Sutherland models
S. M. Pittman, M. Beau, M. Olshanii +1
A one-dimensional quantum many-body system consisting of particles confined in a harmonic potential and subject to finite-range two-body and three-body inverse-square interactions…
Fast Quantum Communication in Linear Networks
Kurt Jacobs, Rebing Wu, Xiaoting Wang +3
Here we consider the speed at which quantum information can be transferred between the nodes of a linear network. Because such nodes are linear oscillators, this speed is also impo…
Sporadic SICs and the Normed Division Algebras
Blake C. Stacey
Recently, Zhu classified all the SIC-POVMs whose symmetry groups act doubly transitively. Lattices of integers in the complex numbers, the quaternions and the octonions yield the k…
Anti-Kibble-Zurek Behavior in Crossing the Quantum Critical Point of a Thermally Isolated System Driven by a Noisy Control Field
Anirban Dutta, Armin Rahmani, Adolfo del Campo
We show that a thermally isolated system driven across a quantum phase transition by a noisy control field exhibits anti-Kibble-Zurek behavior, whereby slower driving results in hi…
Scaling-up quantum heat engines efficiently via shortcuts to adiabaticity
M. Beau, J. Jaramillo, A. del Campo
The finite-time operation of a quantum heat engine that uses a single particle as a working medium generally increases the output power at the expense of inducing friction that low…
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…
Shortcuts to adiabaticity by counterdiabatic driving for trapped-ion displacement in phase space
Shuoming An, Dingshun Lv, Adolfo del Campo +1
The application of adiabatic protocols in quantum technologies is severely limited by environmental sources of noise and decoherence. Shortcuts to adiabaticity by counterdiabatic d…
