⭐ - Featured Role | Apply direct with Data Freelance Hub


This role is for a Quantum Physicist (PhD/MSc) with expertise in quantum sensing, geophysical modelling, and laboratory experiments. The contract is for 3 months, remote in the UK, with a competitive pay rate. Essential skills include Python and signal processing.


Location: UK (Remote)


Contract: 3 months (with potential for 18‑month extension)


Start: January 2026


Salary: Competitive / negotiable


Organisation: Entergaia Technologies – Quantum Sensing & Subsurface Intelligence


Key Responsibilities

Physics Modelling & Simulation



  • Develop forward models for quantum gravimeter response to voids, sinkholes and water ingress, and quantum magnetometer response to ferrous and geological structures.
  • Implement analytical or numerical models for mass‑density contrasts, gravitational fields and gradients, magnetic susceptibility contrasts.
  • Create realistic, physics‑accurate synthetic datasets for AI training.
  • Model the sensor’s transfer function, including vibration coupling, laser phase noise, interferometer stability and gravity‑gradient / magnetic‑gradient effects.
  • Work closely with the AI Specialist to verify the realism of simulated signatures.

Laboratory Calibration & Controlled Experiments



  • Prepare and configure the quantum sensor testbed (atom interferometer alignment, optical system stability, magnetometer sensitivity optimisation, vibration isolation and environmental control).
  • Run controlled experiments with known reference anomalies (known masses, void analogues, water‑equivalent targets, magnetic inclusions).
  • Quantify sensor sensitivities: sub‑µGal (gravity) and pT‑fT (magnetics).
  • Characterise repeatability, drift, temperature dependence and noise bandwidths.
  • Collaborate with NPL to obtain traceable metrology validation.

Sensor Interpretation & Noise Analysis



  • Decompose recorded signals into true anomaly signatures, platform‑induced noise, environmental artefacts and quantum projection noise.
  • Model motion‑induced biases using IMU data.
  • Support the AI team by delivering corrected time series, noise models and uncertainty estimates.
  • Recommend optimised data‑acquisition protocols for future field deployments.

Integration with AI



  • Translate physics constraints into data features.
  • Define physically plausible anomaly signatures.
  • Validate AI‑detected anomalies for physical consistency.
  • Guide feature engineering (gradients, curvature, bandwidth of anomalies).
  • Assist in fusing gravity & magnetic data into a joint physical interpretation.

Technical Leadership in Hazard Interpretation



  • Determine detection thresholds for each hazard type (minimum void size, maximum detectable depth, water ingress sensitivity).
  • Build capability envelopes (performance charts).
  • Provide scientific assessment of feasibility.

Essential Skills & Experience

  • Quantum Sensing & Atomic Physics – experience with cold‑atom interferometry, quantum gravimetry, or atomic magnetometry; understanding of Rabi/Raman transitions, laser phase noise, atom optics, magnetic resonance in atomic vapour cells.
  • Geophysical Modelling – understanding of gravity and magnetic fields in Earth sciences; forward modelling and inversion experience.
  • Laboratory Experimental Skills – hands‑on experience building or operating optical setups, vacuum systems, laser systems, magnetically shielded environments; design and run controlled physics experiments.
  • Signal Processing – analysing noisy scientific data; FFTs, PSD analysis and filtering.
  • Software Skills – Python, MATLAB, or similar scientific computing tools; modelling libraries such as SciPy, NumPy, Fatiando a Terra, QuTiP, COMSOL (desirable).
  • Communication – explain complex physics to engineers and non‑physicists; strong technical writing for reports and publications.

Desirable Skills

  • Experience with quantum gravimeters from Exail, Muquans, Atomionics, Aquark, or research prototypes.
  • Understanding of geotechnical engineering or subsurface hazards.
  • Familiarity with drones, mobile mapping, or rail/road instrumentation.
  • Knowledge of Bayesian filtering, Kalman filters, or motion‑compensation methods.
  • Prior work in NPL, university quantum labs, or national labs.

Qualifications

  • PhD or MSc in Atomic Physics, Quantum Optics, Quantum Sensing, Experimental Physics or closely related field, OR highly relevant industrial/research experience with proof of technical capability.
  • Post‑doctoral or industry experience in quantum sensing or precision metrology (preferred).

Neurodiversity in Quantum Computing Careers: Turning Different Thinking into a Superpower

Quantum computing is one of the most demanding – & exciting – areas in technology. It sits at the intersection of physics, mathematics, computer science, engineering & even philosophy. The problems are complex, the systems are fragile, & the answers are rarely obvious. That’s exactly why quantum needs people who think differently. If you live with ADHD, autism or dyslexia, you may have been told your brain is “too distracted”, “too literal” or “too chaotic” for high-end research or deep technical roles. In reality, many of the traits that made school or traditional workplaces difficult can be huge strengths in quantum computing – from intense focus on niche topics to pattern recognition in noisy data & creative approaches to algorithms. This guide is for neurodivergent job seekers exploring quantum computing careers in the UK. We’ll look at: What neurodiversity means in a quantum computing context How ADHD, autism & dyslexia strengths map onto common quantum roles Practical workplace adjustments you can ask for under UK law How to talk about your neurodivergence in applications & interviews By the end, you’ll have a clearer sense of where you might thrive in quantum computing – & how to turn “different thinking” into a genuine superpower.

Quantum Computing Hiring Trends 2026: What to Watch Out For (For Job Seekers & Recruiters)

As we move into 2026, the quantum computing jobs market in the UK is shifting from hype to harder-edged reality. The wildest forecasts have softened, some early-stage start-ups have pivoted or been acquired, and investors are more selective. At the same time, governments, big tech, defence, finance and pharma still see quantum as strategically important – especially in algorithms, quantum-safe cryptography, optimisation and materials simulation. The result: fewer “blue-sky” roles with no clear roadmap, and more demand for quantum talent that can plug into real programmes, real products and real timelines. Whether you’re a quantum job seeker planning your next move, or a recruiter building teams across hardware, software, theory or adjacent fields, understanding the key quantum computing hiring trends for 2026 will help you stay ahead.

Quantum Computing Recruitment Trends 2025 (UK): What Job Seekers Need To Know About Today’s Hiring Process

Summary: UK quantum computing hiring has shifted from credential‑first screening to capability‑driven evaluation. Employers now value provable contributions across the stack—algorithms & applications, compilation & optimisation, circuit synthesis, control & calibration, hardware characterisation, error mitigation/correction (QEM/QEC), verification/benchmarking, and hybrid HPC/quantum workflows—plus the ability to communicate trade‑offs, costs and feasibility to non‑quantum teams. This guide explains what’s changed, what to expect in interviews and how to prepare—especially for quantum algorithm engineers, quantum software/compilers, experimentalists, quantum control & firmware, cryo/readout engineers, quantum error correction researchers, verification/benchmarking specialists, and quantum‑adjacent product managers. Who this is for: Quantum algorithm/applications engineers, compiler/optimisation engineers, control/firmware engineers, experimental physicists & hardware engineers (superconducting, trapped ion, photonic, spin/neutral atom), cryogenics & RF/microwave, QEC researchers, verification/benchmarking specialists, quantum‑HPC orchestration engineers, and product/BD roles in the UK quantum ecosystem.
