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…
Newton, entanglement, and the graviton
Daniel Carney
Many experiments have recently been proposed to test whether non-relativistic gravitational interactions can generate entanglement. In this note, I consider the extent to which the…
Trapped electrons and ions as particle detectors
Daniel Carney, Hartmut Häffner, David C. Moore +1
Electrons and ions trapped with electromagnetic fields have long served as important high-precision metrological instruments, and more recently have also been proposed as a platfor…
Search for composite dark matter with optically levitated sensors
Fernando Monteiro, Gadi Afek, Daniel Carney +3
Results are reported from a search for a class of composite dark matter models with feeble, long-range interactions with normal matter. We search for impulses arising from passing…
Faster Digital Quantum Simulation by Symmetry Protection
Minh C. Tran, Yuan Su, Daniel Carney +1
Simulating the dynamics of quantum systems is an important application of quantum computers and has seen a variety of implementations on current hardware. We show that by introduci…
Back-action evading impulse measurement with mechanical quantum sensors
Sohitri Ghosh, Daniel Carney, Peter Shawhan +1
The quantum measurement of any observable naturally leads to noise added by the act of measurement. Approaches to evade or reduce this noise can lead to substantial improvements in…
