Abstract: Fluoride crystals doped with rare-earth ions (REI) and pair centers in diamond for fast ($10^{-9}\rm{s}$) quantum computers (FQC) are proposed. As specific systems for REI doping, we propose $Ca_{1-x}Sr_{x}F_{2}$ crystals and their analogues. The $^{4}f$-states with different total orbital angular moments of these ions serve as two-level systems (qubits). Suitable REIs are proposed as well. It is established that the pair $SiV$ and $GeV$ centers in diamond are promising systems for fast optical quantum computers operating at elevated temperatures.

Time-correlated photon pairs are generated by triply-resonant Four-Wave-Mixing in a In$_0.5$Ga$_0.5$P Photonic Crystal cavitiy. The generation rate reaches 5 MHz in cavities with Q-factor $approx 4times 104$, more than one order of magnitude larger than what is measured using ring resonators with similar Q factors fabricated on the same chip.

Deterministic preparation of W states via spin-photon interactions [1.0499611180329804]
We study deterministic preparation of arbitrary size $W$ states with spin systems. We present an efficient operation on three qubits, two being the logical qubits and one being the ancillary qubit. We show how to create a large scale $W$ state out of separable qubits, or double the size of a $W$ state.

Algorithmic Ground-state Cooling of Weakly-Coupled Oscillators using Quantum Logic [52.77024349608834]
We introduce a novel algorithmic cooling protocol for transferring phonons from poorly- to efficiently-cooled modes. We demonstrate it experimentally by simultaneously bringing two motional modes of a Be$+$-Ar$13+$ mixed Coulomb crystal close to their zero-point energies. We reach the lowest temperature reported for a highly charged ion, with a residual temperature of only $Tlesssim200mathrmmu K$ in each of the two modes.

A Quantum Photonic Interface for Tin-Vacancy Centers in Diamond [0.0]
Tin-vacancy centers in diamond exhibit narrow-linewidth emission in nanostructures and possess long spin coherence times at temperatures above 1 K. We integrate SnV$,textrm-$ centers into one-dimensional photonic crystal resonators and observe a 40-fold increase in emission intensity. Our results pave the way for the creation of efficient, scalable spin-photon interfaces based on SnV$,textrm-$ centers in diamond.

We extend the architecture to ions residing in two remote cavities, and we show how continuous monitoring of fluorescence signals from the two ancilla ions leads to entanglement of the qubit ions.
