Nanophotonics, Volume 14, Issue 20, Page 3243-3254, 01 October 2025.Abstract The generation and application of squeezed light have long been central goals of quantum optics. Intensity noise squeezing of bright (coherent) states (“bright squeezing”), in contrast to squeezed vacuum, is relatively underdeveloped. The current state of the art has generally been restricted to narrow operating wavelength ranges and does not ...

Improved Placement Precision of Donor Spin Qubits in Silicon using Molecule Ion Implantation
Advanced Quantum Technologies, Volume 7, Issue 3, March 2024.Donor spins in silicon‐28 are among the best performing qubits in the solid state. P donor placement precision is improved upon, advantageous for qubit readout and coupling, by implanting PF2$\rm{PF}_2$ molecule ions that carry bystander atoms to boost detection confidence.

A Quantum Perspective on Oscillation Frequencies in Axion Dark Matter Experiments
Annalen der Physik, Volume 536, Issue 1, January 2024.The time evolution of signals in axion dark matter experiments, such as CASPEr, is looked at from a quantum perspective. Classically, one expects signals oscillating with a frequency equal to the axion mass. The explanation of where this oscillation frequency appears from a quantum perspective and how it relates to the axion quantum state. The suitable

Quantum Nondemolition Squeezing of a Nanomechanical Resonator [PDF]
, 2005 We show that the nanoresonator position can be squeezed significantly below the ground state level by measuring the nanoresonator with a quantum point contact or a single-electron transistor and applying a periodic voltage across the detector.

Quantum relays and noise suppression using linear optics
, 2020 Probabilistic quantum nondemolition (QND) measurements can be performed using linear optics and postselection. Here we show how QND devices of this kind can be used in a straightforward way to implement a quantum relay, which is capable of extending the ...
