Improved Absolute Polarization Calibrator for BICEP CMB Polarimeters
A. R. Polish, P. A. R. Ade, Z. Ahmed +89
Cosmic birefringence is a hypothesized parity violation in electromagnetism that predicts a frequency-independent polarization rotation as light propagates. This would rotate the l…

BICEP/Keck XX: Component-separated maps of polarized CMB and thermal dust emission using Planck and BICEP/Keck Observations through the 2018 Observing Season
Keck Collaboration, P. A. R. Ade, Z. Ahmed +94
We present component-separated polarization maps of the cosmic microwave background (CMB) and Galactic thermal dust emission, derived using data from the BICEP/Keck experiments thr…

Cascaded quantum time transfer breaking the no-cloning barrier with entanglement relay architecture
H. Hong, X. Xiang, R. Quan +9
Quantum two-way time transfer (Q-TWTT) leveraging energy-time entangled biphotons has achieved sub-picosecond stability but faces fundamental distance limitations due to the no-clo…
