Low-Noise Amplification and Frequency Conversion with a Multiport Microwave Optomechanical Device

2016

High-gain amplifiers of electromagnetic signals operating near the quantum limit are crucial for quantum information systems and ultrasensitive quantum measurements. However, the existing techniques have a limited gain-bandwidth product and only operate with weak input signals. Here we demonstrate a two-port optomechanical scheme for amplification and routing of microwave signals, a system that simultaneously performs high-gain amplification and frequency conversion in the quantum regime. Our amplifier, implemented in a two-cavity microwave optomechanical device, shows 41 dB of gain and has a high dynamic range, handling input signals up to $10^{13}$ photons per second, three orders of magn…

Anti-Racism from the Margins: Welcoming Refugees at Schengen’s Northernmost Border

2018

Through events of solidarity with refugees that unfolded at the Arctic border between Norway and Russia in 2015, we critically address two common analyses of racism and humanitarianism. First, we argue that the often-claimed explanation that racism results from disenfranchised social class fails to identify solidarities across marginalized groups. Furthermore, as anti-Muslim racism has become more mainstream in the Nordic region, solidarity with refugees offers critical positions in relation to political centers. Second, the case demonstrates how humanitarian action and politicized refugee activism are not necessarily separate forms of action but more entangled forms of engagement. The case…
