Very light particles with CP-violating couplings to ordinary matter, such as axions or axion-like particles, can mediate long-range forces between polarized and unpolarized fermions. We describe a new experimental search for nucleons in two 250 kg Pb weights neutrons electrons $^3$He-K co-magnetometer located about 15 cm away. place improved constrains on the products of scalar pseudoscalar coupling constants, $g^n_p g^N_s < 4.2\times10^{-30}$ $g^e_p 1.7\times10^{-30}$ (95% CL) particle...
Ultralight axion-like particles can contribute to the dark matter near Sun, leading a distinct, stochastic signature in terrestrial experiments. We search for such through their neutron-spin coupling by re-analyzing approximately 40 days of data from K-$^3$He co-magnetometer with new frequency-domain likelihood-based formalism that properly accounts effects over all axion coherence times relative experimental time span. Assuming axions make up Sun's vicinity, we find median 95% upper limit...
We report the results of a new search for long range spin-dependent interactions using Rb -$^{21}$Ne atomic comagnetometer and rotatable electron spin source based on SmCo$_{5}$ magnet with an iron flux return. By looking signal correlations orientation we set constrains product pseudoscalar neutron couplings $g^e_p g^n_p/\hbar c<1.7\times10^{-14}$ their axial $g^e_A g^n_A/\hbar c<5\times10^{-42}$ to particle mass less than about $1~\mu$eV. Our measurements improve by 2 orders magnitude...
The realization of scalable systems for quantum information processing and networking is utmost importance to the community. However, building such difficult because challenges in achieving all necessary functionalities on a unified platform while maintaining stringent performance requirements individual elements. A promising approach which addresses this challenge based consolidation experimental theoretical capabilities physics integrated photonics. Integrated photonics devices allow...
Quantum computing promises to provide exponential speed-ups certain classes of problems. In many such algorithms, a classical vector $\mathbf{b}$ is encoded in the amplitudes quantum state $\left |b \right >$. However, efficiently preparing >$ known be difficult problem because an arbitrary $Q$ qubits generally requires approximately $2^Q$ entangling gates, which results significant decoherence on today's Noisy Intermediate Scale (NISQ) computers. We present deterministic (nonvariational)...
