Here we propose a new way to scale up trapped ion quantum computer based on long multispecies ion chains. Mass difference of ions leads to chain segmentation and allows to implement high-fidelity entangling gates.

The goal of this work is to develop Sb-based nBn infrared detectors operating at 2 µm with Quantum Efficiency (QE) exceeding 99%. These detectors have the potential to significantly increase the sensitivity of future generations of the Laser Interferometer Gravitational-Wave Observatory (LIGO) by exploiting quantum entanglement for sub-Poisson limited laser interferometry.

High-precision time synchronization is a fundamental requirement for quantum networks. We simulate a global time distribution network by using quantum clock synchronization – sharing entangled photons between satellite-ground station pairs. This provides sub-nanosecond to picosecond level precision over intercontinental scales (better than GPS).

We propose a scheme for generating polarization-entangled photons using the quantum Zeno effect. The observing medium is a series of 4-level atoms coupled to two waveguides. Bunching is suppressed, yielding bipartite and tripartite polarization entanglement.
