Constraints on Primordial Magnetic Fields from the Lyman-α forest

Kavli Affiliate: Martin Haehnelt | Summary:We present the first constraints on primordial magnetic fields from the Lyman-$α$ forest using full cosmological hydrodynamic simulations. At the scales and redshifts probed by the data, the flux power spectrum is extremely sensitive to the extra power induced by primordial magnetic fields in the linear matter power spectrum, at […]

Quantum networks using rare-earth ions

Kavli Affiliate: Wolfgang Tittel | Summary:We review concepts and recent work related to creating light-matter interfaces for future quantum networks based on rare-earth ion-doped crystals. More precisely, we explore their unique suitability for creating photon sources, optical quantum memories for light, and qubits that allow quantum information processing. In addition, we review the state-of-the-art of […]

All-optical computing with beyond 100-GHz clock rates

Kavli Affiliate: Alireza Marandi | Summary:A computer’s clock rate ultimately determines the minimum time between sequential operations or instructions. Despite exponential advances in electronic computer performance owing to Moore’s Law and increasingly parallel system architectures, computer clock rates have remained stagnant at $sim5~mathrmGHz$ for almost two decades. This poses an intractable problem for applications requiring […]
