We show that quantum entanglement can provide an exponential advantage in learning properties of a bosonic continuous-variable (CV) system. The task we consider is estimating a pro…
Variational quantum algorithm for enhanced continuous variable optical phase sensing
Jens A. H. Nielsen, Mateusz Kicinski, Tummas N. Arge +7
Variational quantum algorithms (VQAs) are hybrid quantum-classical approaches used for tackling a wide range of problems on noisy intermediate-scale quantum (NISQ) devices. Testing…
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…
