100physical qubits · target
Prototype and baseline
Choose a hardware path; validate the 100-physical-qubit target through published calibration, gate fidelity and uptime measurements. Build the control and test stack.
01 / IRELAND'S QUANTUM
From 100 to one million.
Mike English and prospective backers envision a ten-year climb in physical qubits. This is a proposed sequence of targets, not a funded build schedule or a promise of delivery.
READ THE NUMBER CAREFULLY
Scale has to earn its meaning.
These targets refer to physical qubits, not error-corrected logical qubits. Actual useful capacity depends on coherence, gate accuracy, connectivity, error correction, controls and uptime. The hardware architecture is not selected here. Targets must be revised against engineering results and funding.
Each stage has a test: publish a reproducible benchmark, then progress only when reliability and quality keep pace with count. Parallel chips or modules do not automatically behave as one million useful qubits.
TEN-YEAR TARGET LADDER · ILLUSTRATIVE
YEAR 02
200physical qubits · target
Reproducibility
Repeat benchmark runs, improve yield and monitor drift. Create a small developer programme on a simulator before promising hardware time.
YEAR 03
500physical qubits · target
Modules
Test modular controls, packaging and readout. Publish honest quality metrics, not only a qubit count.
YEAR 04
1,000physical qubits · target
Error-correction trials
Compare candidate error-correcting codes and demonstrate repeated syndrome extraction where hardware quality permits.
YEAR 05
3,000physical qubits · target
Scale the operations
Automate calibration, fault detection, thermal or optical infrastructure and secure scheduling for larger experiments.
YEAR 06
10,000physical qubits · target
Network the modules
Demonstrate reliable inter-module links or an equivalent scale-out approach; stress-test compiler, queue and power demands.
YEAR 07
30,000physical qubits · target
Useful logical work
Track logical error per operation and reproducible workloads. Progress requires quality to improve as physical capacity rises.
YEAR 08
100,000physical qubits · target
Research service
Offer controlled research access only if verified capacity, support, security and service reliability meet published criteria.
YEAR 09
300,000physical qubits · target
Industrial validation
Test demanding scientific workloads with independent benchmarks and explicit classical baselines. Do not equate scale with advantage.
YEAR 10
1,000,000physical qubits · target
A million-qubit ambition
Target aggregate physical qubits across a validated architecture. Report usable logical qubits and error rates separately; this milestone is not guaranteed.
DEPENDENCIES
What makes a roadmap credible?
Hardware choice, fabrication or sourcing, controls, cryogenics or optics, talent, clean-room access, classical computing, secure operations, capital and independent benchmarking all matter. No named backers or partners are claimed. Before offering access, the project would need a validated machine, clear ownership, safety and security review, and support commitments.
We would report the gap between planned and achieved milestones. The million-qubit goal is aspirational and may prove infeasible on this timetable.
