We have performed a reference-free measurement of the transition energies of the 1s2p1P1 → 1s2 1S0 line in He-like argon, and of the 1s2s22p 1P1 → 1s22s2 1S0
We recently developed a surface integral equation method where the electric field and its normal derivative are chosen as the boundary unknowns. After reviewing
We present techniques to obtain small circuits which also have low depth. The techniques apply to typical cryptographic functions, as these are often specified
