We describe a scalable angular spectrum (SAS) algorithm with zoom capability for numerical propagation of scalar wave fields in homogeneous media. It allows for propagation models where the destination pixel pitch is larger than the source pixel pitch, requires a computational complexity proportional to...
A modified angular spectrum propagation that uses the averaged output of optical propagations with randomized input phases was used to estimate the effects of diffraction on the optical propagation for both the experimental parameters in the experiment (Supplementary Fig. 19) and also for the scaled-...
Figure 6b shows the calculation of the output THz spectral power with an increasing propagation distance within LN. The simulation was performed by setting the input laser pulse to have an energy of 2.3 J, a fluence of 0.08 J cm−2, a Gaussian spectrum with a FWHM of 78 nm...
Gate fidelity:The main sources of errors in quantifying the C-NOT4gate’s operation are spontaneous emission and population rotation errors. The errors are averaged over the 25qubit configurations. The average spontaneous emission error from the Rydberg level is given by\({E}_{sp,r}=\frac{1}...
whereωis the angular frequency of the RF signal,Nis the number of taps,h(n) is the tap coefficient (amplitude) of each tap, and ΔTis the time delay interval. As we can see from Eq. (1), the shape of the MPF can be adapted to different requirements and applications through multidi...
emission model for optical microcavities were then carried out to fit thep-pol angular PL profile, usingRIPas the only fitting parameter (see “Methods” section). The well-established method for analyzing TDM orientation is adapted from the field of multilayer thin film organic light-emitting ...
Reconfigurable waveform and frequency spectrum generation Tunable microwave photonic filters (MPFs) are crucial for enhancing the performance, flexibility, and reliability of modern communication and sensing systems13,20. To demonstrate this function, the processor is configured as a transversal tapped delay...
and multi-qubit or even global entangling gates can be performed by carefully controlling the intensity and spectrum of the lasers on all ions.85,86 Such multi-qubit operations are useful for the generation of certain entangled states9,22, and for the simulation of long-range global Ising inter...
The extension of the above integrated photonics technology, including detectors and waveguides to optical cross-connect switches, to the visible and blue portions of the spectrum where atomic ions respond will be highly valuable to the trapped ion quantum optical network. Alternatively, noiseless photoni...
These sites break down omni 360° cells into smaller angular range sectors, such as 120° sectors. These directional systems help to reduce interference due to channel overlap and to increase the transmit and receive distance ranges of the base station. Accordingly, the cells can cover a larger...
