Quantum sensing

GPS jamming makes quantum navigation necessary, but the buyers are defence programmes at R&D scale and the sensors are still hand-built lab racks.

  • Bear
  • Early
  • $1.7B by 2035

The callThe bear case wins for now: demand is DARPA, DIU, Navy and NGA programmes buying prototypes, the cycles are long, and the first production contract is not dated before 2031. If navigation moves to low-rate production the market goes from $450M to $1.7B.

Fig. 1The balance. Drivers and catalysts against restraints, each block sized by its weight; catalysts hang dashed because they have not happened yet, sized by their odds. It tips toward the restraints.
  1. D1GPS is routinely jammed and spoofed, and inertial units drift within hours, so every aircraft, ship and drone needs a way to find its position without satellites.
  2. D2Putting the physics on photonic chips, integrated lasers and readout, takes the cost of a non-drifting sensor down by an order of magnitude.
  3. R1Demand is defence procurement at R&D scale, with long cycles, few buyers and heavy qualification capital; the serviceable market drifts from $0.52B to $0.83B by 2031.
  4. R2A merchant photonic foundry such as OpenLight could put the readout parts in its standard kit before a startup builds margin.
  5. R3The exits are small and in stock: Vector Atomic to IonQ for about $181.5M; Infleqtion's 55x revenue SPAC print is the fragile input.
  6. C1A NATO-tier production contract for 1,000 or more quantum navigation units moves the field from prototype to production; NGA's MagQuest targets acquisition in 2030.2031

What changedthe record, newest first
  • 17 Jul 2026The quantum money that's actually earning revenue right now isn't in computers, it's in sensing and metrology. €200m into a company that measures chips, the same week the industry was still arguing about when fault tolerance arrives.
  • 24 Jun 2026A maker of cryogenic cooling hardware confirms where the near-term money in quantum sensing actually sits: government defence programmes, not commercial sockets. Its anchor is a late-stage Arctic-sensing contract whose tender was written around the company. That firms up the read that quantum sensing's demand pull is still mostly long-cycle procurement, and it is a reminder that every cold sensor has a cooling layer beneath it, also held by a small set of incumbents.
