Project Title: ​Advanced CV-Quantum States Propagation & HW Validation - 10km Fiber Setup

Job ID: 40275249

Budget: €250 – €750 EUR

​Project Description:
​I am looking for a PhD-level Photonics/Quantum Engineer to develop a 100% accurate simulation and a certified hardware list (BOM) for a specific optical experiment.
​The goal is to analyze the fidelity of Gaussian States (Squeezed/Coherent) after a 10km fiber-optic delay line using a time-domain multiplexing approach.
​The simulation MUST include and validate the following chain:
​Optical Source: Phase-stable Laser (CW or Pulsed) at 1550nm + Squeezing Source.
​Encoding Stage: High-speed modulation (AM/PM) with specific Vpi and insertion loss constraints.
​Delay Line: 10km SMF-28 Fiber (including Rayleigh scattering and phase-drift modeling).
​Interference Stage: Local Oscillator (LO) synchronization and balanced beam splitting.
​Detection: Balanced Homodyne Detector (BHD) with Shot-Noise Limited performance.
​Signal Processing: Simulation of the ADC/FPGA sampling rate required to resolve the pulses.
​Deliverables (Non-Negotiable):
​A Functional Simulation: Providing the Wigner Function and State Fidelity (F) results.
​A Certified BOM (Hardware List): You must provide a list of 100% compatible components (Laser, Modulator, Fiber, Detector). You must guarantee that if these parts are purchased, the physical experiment will match the simulation results.
​Tolerance Analysis: You must specify the maximum allowed Laser Linewidth (kHz) and the minimum CMRR (dB) for the detector to maintain stability.
​Confidentiality:
The specific algorithm and the final application of this setup will only be disclosed after a formal NDA (Non-Disclosure Agreement) is signed. I am looking for a partner for a long-term collaboration.
​Budget: Competitive. Quality and 100% technical convergence are the priorities.
