Overview and status of BICEP Array's BA4-90/150 CMB polarimeter
M. A. Petroff, P. A. R. Ade, Z. Ahmed +83
The inflation paradigm postulates a period of rapid expansion in the early Universe, which would generate gravitational waves. These tensor perturbations would produce a faint B-mo…
Design and Performance of 220 and 270 GHz Bandpass Filters for BICEP Array
A. Steiger, The BICEP/Keck Collaboration, P. A. R. Ade +90
The BICEP Array (BA) is the latest in the BICEP/ Keck series of experiments that aim to measure the polarization of the cosmic microwave background (CMB) with small aperture polari…
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…
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…
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…
