Dataflow all-reduce for reconfigurable processor systems
Roughly described, a system for data parallel training of a neural network on multiple reconfigurable units configured by a host with dataflow pipelines to perform different steps in the training CGRA units are configured to evaluate first and second sequential sections of neural network layers based on a respective subset of training data, and to back-propagate the error through the sections to calculate parameter gradients for the respective subset. Gradient synchronization and reduction are performed by one or more units having finer grain reconfigurability, such as an FPGA. The FPGA performs synchronization and reduction of the gradients for the second section while the CGRA units perform back-propagation through the first sequential section. Intermediate results are transmitted using a P2P message passing protocol layer. Execution of dataflow segments in the different units is triggered by receipt of data, rather than by a command from any host system. |

Scalable feedback control of single-photon sources for photonic quantum technologies
Typically, quantum systems are very sensitive to environmental fluctuations, and diagnosing errors via measurements causes unavoidable perturbations. Here, an in situ frequency-locking technique monitors and corrects frequency variations in single-photon sources based on resonators. By using the classical laser fields used for photon generation as probes to diagnose variations in the resonator frequency, the system applies feedback control to correct photon frequency errors in parallel to the optical quantum computation without disturbing the physical qubit. Our technique can be implemented on a silicon photonic device and with sub 1 pm frequency stabilization in the presence of applied environmental noise, corresponding to a fractional frequency drift of <1% of a photon linewidth. These methods can be used for feedback-controlled quantum state engineering. By distributing a single local oscillator across a one or more chips, our approach enables frequency locking of many single photon sources for large-scale photonic quantum technologies. |

Multi-focal display based on polarization switches and geometric phase lenses
Some implementations disclosed herein include devices, systems, and methods that display images at multiple focus distances on HMDs. The systems can avoid or mitigate vergence-accommodation conflict (VAC) and depth-blur conflict (DBC) experienced by users on traditional HMDs. Some implementations use a geometric phase lens and a circular polarization switch. The geometric phase lens passively changes its power depending on the light's circular polarization. The circular polarization switch changes the polarization of the light at appropriate times. With the circular polarization switch and geometric phase lens positioned over an HMD screen, the system can quickly change the apparent distance to the screen, which in turn changes the accommodative state of the eye needed to focus on the rendered image. |

Method and system for analyst of crystals and crystallization
The disclosure relates to methods and systems for the analysis of compounds in a crystalline state and/or undergoing crystallization.

One can define which functional group types (e.g., region) are most perturbed (positive, intense auto peak) and observe how the different auto peaks begin to have greatest intensity change. These changes in auto peaks in the synchronous plots for the different stages of crystallization can provide information as to the dynamics of the process from amorphous to crystalline state. |
