In situ calibration of unitary operations during quantum error correction
Jonathan Kunjummen, Jacob M. Taylor
Quantum error correction uses the measurement of syndromes and classical decoding algorithms to estimate the location and type of errors while protecting the encoded quantum bits.…
Derandomized shallow shadows: Efficient Pauli learning with bounded-depth circuits
Katherine Van Kirk, Christian Kokail, Jonathan Kunjummen +7
Efficiently estimating large numbers of non-commuting observables is an important subroutine of many quantum science tasks. We present the derandomized shallow shadows (DSS) algori…
Feasibility of a trapped atom interferometer with accelerating optical traps
Gayathrini Premawardhana, Jonathan Kunjummen, Sarthak Subhankar +1
In order to increase the measured phase of an atom interferometer and improve its sensitivity, researchers attempt to increase the enclosed space-time area using two methods: creat…
Randomized measurement protocols for lattice gauge theories
Jacob Bringewatt, Jonathan Kunjummen, Niklas Mueller
Randomized measurement protocols, including classical shadows, entanglement tomography, and randomized benchmarking are powerful techniques to estimate observables, perform state t…
Decoherence from Long-Range Forces in Atom Interferometry
Jonathan Kunjummen, Daniel Carney, Jacob M. Taylor
Atom interferometers provide a powerful means of realizing quantum coherent systems with increasingly macroscopic extent in space and time. These systems provide an opportunity for…
Shadow process tomography of quantum channels
Jonathan Kunjummen, Minh C. Tran, Daniel Carney +1
Quantum process tomography is a critical capability for building quantum computers, enabling quantum networks, and understanding quantum sensors. Like quantum state tomography, the…
Mechanical Quantum Sensing in the Search for Dark Matter
Daniel Carney, Gordan Krnjaic, David C. Moore +32
Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matt…
High precision Optical AC Magnetometry using Dynamical Decoupling
Manish K. Gupta, Jonathan Kunjummen, Xiaoting Wang +1
We propose a magnetometer for the precise measurement of AC magnetic fields that uses a Terbium-doped optical fiber with half-waveplates built into it at specified distances. Our s…
