Fully guided and phase locked Ti:PPLN waveguide squeezing for applications in quantum sensing
Renato Domeneguetti, Michael Stefszky, Harald Herrmann +4
This work reports a fully guided setup for single-mode squeezing generation on integrated titanium-indiffused periodically poled nonlinear resonators. A continuous wave laser beam…
Long Distance Nonlocality Test with Entanglement Swapping and Displacement-Based Measurements
Anders J. E. Bjerrum, Jonatan B. Brask, Jonas S. Neergaard-Nielsen +1
We analyze an all-optical setup which enables Bell-inequality violation over long distances by exploiting probabilistic entanglement swapping. The setup involves only two-mode sque…
Quantum Repeater using Two-Mode Squeezed States and Atomic Noiseless Amplifiers
Anders J. E. Bjerrum, Jonatan B. Brask, Jonas S. Neergaard-Nielsen +1
We perform a theoretical investigation into how a two-mode squeezed vacuum state, that has undergone photon loss, can be stored and purified using noiseless amplification with a co…
40 km Fiber Transmission of Squeezed Light Measured with a Real Local Oscillator
Iyad Suleiman, Jens Arnbak Holbøll Nielsen, Xueshi Guo +4
We demonstrate the generation, 40 km fiber transmission, and homodyne detection of single-mode squeezed states of light at 1550 nm using real-time phase control of a locally genera…
Deterministic quantum phase estimation beyond the ideal NOON state limit
Jens Arnbak Holbøll Nielsen, Jonas Schou Neergaard-Nielsen, Tobias Gehring +1
The measurement of physical parameters is one of the main pillars of science. A classic example is the measurement of the optical phase enabled by optical interferometry where the…
Steering-based randomness certification with squeezed states and homodyne measurements
Marie Ioannou, Bradley Longstaff, Mikkel V. Larsen +5
We present a scheme for quantum randomness certification based on quantum steering. The protocol is one-sided device independent, providing high security, but requires only states…
