Superconducting antiqubits achieve optimal phase estimation via unitary inversion
Xingrui Song, Surihan Sean Borjigin, Flavio Salvati +4
A positron is equivalent to an electron traveling backward through time. Casting transmon superconducting qubits as akin to electrons, we simulate a positron with a transmon subjec…

Sub-micron Circuit Fabrication on Diamond Anvils for Mesoscopic High-Pressure Experiments
Z. R. Rehfuss, K. Zheng, S. L. Gould +2
We present a novel fabrication procedure to produce high-quality lift-off structures on diamond anvils extending from the culet down to the slanted facets. Feature sizes down to 50…
