Developer platform/toolkit to encode & retrieve data in quantum-field excitations (quantum memory)

My girlfriend shared a startup idea with me, and I genuinely felt proud of how creative and ambitious she is. Startup Idea: Store your data in spacetime using quantum fields According to the Bekenstein Bound, 1 cm³ of space can store ~10⁶⁹ bits (more than all hard drives on Earth). Quantum fields fill all of spacetime. Every point has a field value. Particles aren’t solid objects; they’re localized excitations (ripples) in these fields. The electromagnetic field carries photons, the electron field carries electrons, etc. This means the universe already stores information in field configurations. The state of every particle, including its position, momentum, and spin, is encoded in the field at every point. Think: “The universe is a giant quantum hard drive; every particle, force, and event is information encoded in field excitations.” How to Intentionally Store Data in Fields: - Encode information into a field - Excite the field with energy - Stabilize & propagate - Error correction - Retrieve it later Step 1: Encoding Map data to physical properties of field excitations: - Photons: polarization, phase, freq. - Electrons: spin or orbital state - Atoms: ground vs. excited states This is already standard in quantum computing and quantum communications. Step 2: Excitation Energy is required to create the excitation: - Laser pulse: photon in the EM field - Microwave pulse: spin flip in e⁻ - Optical trap: atomic state change The excitation appears as a localized bump in the field and obeys quantum rules (superposition, entanglement possible). Step 3: Stabilization & Propagation Bare excitations decay quickly: - Photons scatter - Electrons relax Solutions: Optical fiber or free space: Photons travel at ~300,000 km/s (used in quantum key distribution). Real-world networks: China (>2,000 km), Europe (Toshiba, ID Quantique). Quantum memory: Trap the state in matter - Rb ensembles: store photons for ms - Rare-earth crystals: up to 6 hours - NV centres in diamond: 1-second coherence Step 4: Error Correction Fields fluctuate due to vacuum noise and thermal noise. Countermeasures: - Quantum error correction codes - Topological protection Step 5: Retrieval Measure the field state: - Photon: avalanche diode / SNSPD - Electron spin: fluorescence readout - Atom: laser-induced fluorescence Measurement collapses the state, but the bit is retrieved. Repeatable using weak measurement or QND (quantum non-demolition). Want to Store 1 Bit in Spacetime Today? Yes, it’s simple: - Polarize a photon. - Send it. - Detect it. You just wrote to the electromagnetic field of spacetime.
