On estimating operator norm distance, with optimal trace distance estimation when one state is pure
Yupan Liu, Qisheng Wang, Zhan Yu
We investigate the computational complexity of estimating the operator norm distance , defined via the operator norm , give…
High fidelity preservation of photonic hyperentanglement in a free-space optical delay line
Yu Guo, Arya Chowdhury, Pranay Tiwari +3
Photonic hyperentanglement enables increased information capacity and enhanced functionality for quantum communication and networking. However, synchronization of hyperentangled ph…
Reply to 'Comment on "Ideal clocks -- a convenient fiction"'
Krzysztof Lorek, Jorma Louko, Andrzej Dragan
For a quantum scalar field that is confined in a uniformly linearly accelerated cavity in Minkowski spacetime and interacts linearly with a scalar field that is not confined in the…
Mesoscopic scattering dynamics under generic uniform SU(2) gauge fields: Spin-momentum relaxation and coherent backscattering
Masataka Kakoi, Christian Miniatura, Keith Slevin
We investigate the time- and momentum-resolved dynamics of matter waves undergoing elastic scattering from a disordered potential in the presence of spatially uniform SU(2) gauge f…
Numerically Optimizing Shortcuts to Adiabaticity: A Hybrid Control Strategy
Bo Xing, Jesús G. Parejo, Sofía Martínez-Garaot +2
Achieving fast, excitation-free quantum control is a vital challenge in modern quantum technologies. In many cases, shortcuts to adiabaticity enable fast adiabatic-like protocols,…
Elucidating magnetic structure with optical dopants: erbium-doped GdSiO
Luke S. Trainor, Masaya Hiraishi, J. -R. Soh +1
The narrowness of the optical transitions of rare-earth-ion dopants makes them highly sensitive probes of their environment. We measured the optical transitions Er dopants t…
